One of the questions that Cindy and I get asked all the time since installing a brand new EVO 2.5" Stage 4 Boost Lift and 37" Cooper STT Pros on our Jeep JL Wrangler Rubicon Unlimited is, do you have any rubbing? Being that we got our Coopers in a 13.50 width and have them mounted on KMC XD231 beadlock wheels that have 4.75" of back spacing, people have been wanting to know if they rub at a full turn, at a full stuff or at a full turn and stuff. In this episode of the JL JOURNAL, you'll get to see JET Li being taken out to do some flex testing, to find out where all his problem spots will be and what we did to help address them. We hope you find this video to be helpful in your JL build. - Авто та транспорт
Got to meet Eddie and his wife at the Jeep display at EJS2018 in Moab a few days ago! Very nice and got to talk about the new JL a bit and got a pic with Eddie. Hope the rest of your time in Moab was fun!
Hey Matt, it was a real pleasure to meet and talk with you in Moab. I hope you had a great time out there.
Great video! Your offroad knowledge and simple explanations are second to none. You're the reason I own a Jeep Jl Rubicon unlimited. Thanks
LOL!! I'm truly humbled. Congratulations on your new Jeep and for being a part of the family :)
Again no BS, just great information. Life long Toyota guy I will be venturing into Jeep territory this weekend with a new purchase due to Wayalife. Great content.
Thank you. We're so happy to hear you enjoy our videos and that we've been of help to you.
Really cool to see the progress from the day you guys picked it up at the dealer.
So glad that you've been enjoying the journey :)
I have the same JLU with the same size lift as well as tires. I just got it out and had the same issue. Lucky me I found this video and will do this same process. I am a member so I look forward to our next adjustments lol! Love the channel and hope to bump into you someday. Eddie get us some ideas for rear bumpers please!!!!
Thanks for the info and demonstration.....my mother-in-law is about to buy a new JLU Rubicon and wants me to put on a 2.5” lift and 37’s and now I know that I need to do some slight mods to the fender liners
Awesome, glad that we could be of help to you :)
Great info dude. I feel like this addresses concerns about a pretty common upgrade package. Sweet
Glad to hear it!
I'm running Mopar's 2" lift on my JLUR with 35's and other than the minor spring bow and the axles being off-centered, it drives and wheels flawlessly. They did such an incredible job with the JL. I'm impressed how little your 37s make contact. Looks like your gate is holding up well, too.
The Mopar kit is a really nice kit. In fact, we almost went with it but knew we wanted to run 37's. Regarding the tailgate, here's a link to show you what we did to make it work. jlwrangler.com/showthread.php?886-CARRY-a-37-quot-SPARE-TIRE-on-a-JL-WRANGLER-TAILGATE-with-LoD-RISER-BRACKETS
Excellent. I'll look into those when they're available. Right now, my spare is essentially stuffed into the bumper. It just barely fits, but since it's on the stock rim, the tail gate bump stops are still long enough to do their job. However, the tailgate is being lifted just a smidge when its closed and that I am not a fan of.
Do you have ParkSense on your Jeep? I'm curious if sticking the camera out a couple extra inches affects how that detection works. Of course, even with all the technology these things come with, I still look back when I'm in reverse!
Sorry, didn't get that with our JL. Just the back up cam and like you, I still look over my shoulder anyway :)
I could live with that small amount of damage. Thanks for the demonstration it helps me out a lot.
Glad to hear that we could be of help to you :)
Hey Eddie thanks for another informative video. I wasn’t too keen on the JL before I started watching your journal but now I’ve come around a bit...You do a better job at selling the JL than Jeep does. Looking forward to what the future holds for ur project. Based on this vid bumpers & and fenders not too far off?
LOL!! Sure wish Jeep thought as much :D Regarding future mods, we have a new LoD front bumper installed and a video will be coming for that soon. We really like the factory fenders and hope to keep them for as long as possible.
I'm planning on 2.5 lift (icon stage 4) and 37s (atturo MT). This video was exactly what I was looking for. Thanks for the great video and it was easy to understand!
2021 rubicon ecodiesel
Glad it was helpful!
@@wayalife hopefully I get to see you on the trails! I'm in socal.
Thx man a lot of help for me before I upgrade
Awesome, glad to be of help :)
Great video and informative. Thanks Im debating buying a JL Unlimited rubicon
Glad to hear it. I think you'd love it.
One more inch of lift should take care of it. One thing I would like to have seen you try is a set of 35s on the stock suspension. Jeep said they would fit without rubbing. At least on the Rubicon.
LOL!! It was just minor rubbing of a piece of plastic. I personally like a low center of gravity and would hate to think I'd need to run 1" more of lift just to prevent something so simple especially when the fix for it cost NOTHING :)
I did the same thing with my 2018 JL, but it makes me nervous having wires unprotected on the rear fender from mud and debree flying up from the tires.
Eddie and Cindy, thanks for all your latest videos. Love them.
Mind to to measure your coopers please from top to bottom? Just wondering how they really are as my BFG KM2's in 37" seem to be more on the 35.5" and the 35" more close to 33.5". Thank you
ALL tires have a true measurement that is shorter than what is written on the sidewalls, this is TOTALLY NORMAL. The only time true size should ever be taken into consideration is when calibrating your speedometer. Otherwise, ALL manufacturers refer to what's on the sidewalls when talking about lifts or other modifications. In other words, if a manufacturer says their lift kit is designed to run 37's, they are talking an advertised 37x12.50 and NOT a tire with a true 37" measurement. To get that, you would have to run a 40" tires. With all that said, this link should help give you perspective on things: wayalife.com/showthread.php/35075-The-Ultimate-TRUE-TIRE-SIZE-Database
Love all your videos and info Eddie! I just picked up my white JL Rubicon Unlimited and got a 2.5” lift and 37” BFG MT KM3s....after you did the work in this video have you recalibrated the Jeep for gearing, speedo etc...? I have seen others who post that you have too but noticed that was not something you covered in this vid.
I did a separate video for it ua-cam.com/video/81_evB9At3I/v-deo.html
Great video!! Love it! Subscribed
Awesome! Thanks. :)
I could be wrong, but I think that removing those brackets caused the bumper to shift up and damage the body while you were in moab. You may have been able to move it with your own strength, but if you look closely, those brackets that held the plastic trim pieces also acted as another connection between the rear bumper and the frame. The bumper damaged the corners of the body in moab where those brackets should have been holding the bumper in place. I would just remove that inner plastic piece that was connected to each bracket and reshape the fender liner. Just my 2 cents. Otherwise a very awesome and informative video! Best Jeep videos of youtube!
Nice change Awesome thanks
I am thinking about putting a 3.5” lift and 37’s on my JLUR. How can I keep them from sticking out so far?
Amazing...keep videos coming!
Thank you :)
Looking to do a lift soon but couldn’t help and put the 37x12.50/17 that were laying in the garage I on the the stock Rubicon wheels while I gather some parts and research on what lift I want to go with
The only rubbing I’m getting with on road use is on the front Oem steel front bumper skid plate when turning full lock and on passenger side rear very little on plastic liner
My question is are there steering stop bolts that can be adjusted on the JL like there was on JK?? or is that not recommended to do?
will be short term waiting on spidertrax hubcentric spacers to arrive but looks like they’re weeks out on arrival
thanks for sharing this.
You bet :)
How is the clearance after you replaced the control arms ?
In general I think your have a ton of Jeep knowledge and your videos are fantastic. This one I think I need to provide a little critique in hopes that some comment-readers will understand what I'm about to point about before they go order 37's for their JL with a 2.5" boost.
Tire sizes are designed in families. A 37" class tire from one manufacturer is will not be the same size as a 37" tire from another manufacturer. There is actually quite a wide tolerance band on acceptable sizes that can be sold within a family of tire. In the industry, a tire size family is designed for by designing to the "max grown" or largest size of that tire size family.
I bring this up because laymen watching your video will think "if it works for Wayalife (an authority on all things Jeep), it must be work for me." Only to find out they may get rubbing that could yield fender damage. This would be because the tire they purchased could represent max grown tire size within that family, or close to it, while the tire you chose for this video might be further towards the smallest size of the tire size family.
So the best way to avoid this after watching this video would be to:
1. Look up what tires Wayalife is running in this video, and look up what the design tire OD for that model is
2. Make sure the tires that you purchase are equal to, or smaller than, the design OD for the model that Wayalife is using
Otherwise, the rubbing you get might be significantly worse!
You assume there are 37's out there that are bigger in diameter than a Cooper STT Pro. Of all the 37's that I've personally run over the years, I can assure you that these are about as big as they come. If anything, I have run others that are SMALLER than them. The steps I've taken to address the rubbing I was getting has also worked for a myriad of people running different 37's as well.
Love your vids guys!!!
Thank you :)
Im running a 3.5 inch rustys on my jk an they clear 37s np.So maybe another inch will do,that is what she said also.
The JL is a totally different animal than a JK.
Another great video which further makes things complicated, I bought a rubicon recon last year with the idea of trading for the jl if there were significant improvements.
So far to make my Rubicon recon 2.5” lift and 37s
1. Change fender flares, jl Rubicon has it
2.get Oscar big bore steering box, jl pretty much has it
3.4.88 regear, seems like the jl is fine with 4.1
4. Driveshafts upgrade maybe not super necessary on the recon but the jl with the funky fad and reworked exhaust negates that, plus no driveshafts or gears for jl yet but that could be a negative. Sorry I’m rambling but I’m about to drop big $$ on mods and I’m trying to do it once and only once but choosing which rubicon the recon or the jl I just don’t know so I’m just asking since you’ve been modding the old and new what do you think put a lot into the known rubicon recon or much less in the unknown jl ?
If your end goal is to run 37's, I personally would start off with a JL and for all the reasons you've stated. So far, I have found it to be a BETTER Jeep.
Get the JL Rubi man. YOLO
Another great info video.. .what's the back space of ur rims...if u push the rim out more would that give u more room?
What you're looking at is 4.5" of back spacing.
Hey Wayalife, do you think the 2.5ift from Mopar would have similar results? Or even better because I assume it has the proper track bars(?).
The Mopar kit is only a 2" lift and it does NOT come with new track bars.
Pardon my ignorance, if you wanted to, would getting new fenders like the metal cloak tube fenders remove this issue. I'm assuming you would want the smallest lift to keep center of gravity low. Basically I want to add a 2.5 lift but do what I can to avoid having to reform plastic as time goes on. Could getting aftermarket fenders fix this?
Only if the aftermarket fenders in question get rid of the factory fender liners because that's where the problem resides. But then, you could always just do that without having to buy a thing.
Hi there, new to this channel- where about is this shot? The scenery looks awesome.
Carson City, NV.
just out of curiosity,wouldn't lowering the air pressure in the tires,help out in the clearance issues?? my thought,is with less air,the tires would be overall alittle lower,and with more flex also...i would think,it would make a difference in those areas...it appeared the tires were not aired down...i may be wrong...just saying.....
The only place less air would effect is the bottom of your tire - the point where it meets the ground. Think about it.
Just checking out the video out again and was wondering if you had aired down for it and if that would had kept you from rubbing? Sorry, I didn't check all the comments so I'm not sure if this question was asked before.
Airing down will only affect the bottom of the tire as it forms to the terrain it makes contact with.
Eddie now that your running a 3.5” lift do you think that’s a better option for 37’s out of the gate or should I go with a 2.5” if I am not wheeling as hard as you guys? Mainly fire/forest roads that are rutted and smaller rocky areas but nothing quite as extreme as what you guys see. Thx!
From what I'm hearing from you, 2.5" will be all the lift you need and it'll do a better job of keeping your ride nice.
Are you still running the stock axels in this video or have you upgraded to the Prorocks. Stock axels on JL dana 44's? Ive seen the tubing video you posted just wanted to ask what your running in this video. Thanks
This video was made over a year ago. We were still running factory axles back then.
Hi dear. Love ur video. I have 22 rims. I m going to upgrade to 37s. So how much lift i need
I dont need much gap between fendors and tires. So 3 inch would be ok i think.
Yes, 3" would get the job done.
Excellent video brother, how does the JL drive on the road past 60mph with the lift and on 37's?
Like there's no difference at all from stock - even up to 85 MPH.
As someone who has so much experience with lifts, and the same Jeep as I have, I've heard mixed reviews on the Mopar lift. Any thoughts?
What you heard is right. It's a good lift but one that will give you more lift than is advertised and that can be an issue. Also, the front springs are soft and have had bowing issues but nothing that can't be corrected with new spring isolators.
If you shave all those bumps off the tires they might not rub
:D
what about reshaping the piece you removed? it looked like there was space to push it in.
You can do that if you really want to keep it.
New jeep guy here! I'm going with a 2.5" lift with 37's and I'm just an over lander with no intentions on rock crawling unless I have to in order to get out of the woods. With that said, I have a roof top tent and other gear coming to be mounted. So my question is what gears do u recommend for me right now? Thank you as always and keep the videos coming.
I suppose it depends on what transmission you have and whether or not you have a Rubicon with 4.10 gears. If you have an automatic and 4.10's, I would run them as is before spending any money on a re-gear. I think you might find that it'll get the job done and that will save you a TON of money. IF you decide that you want more power, 5.13 is what I would recommend.
Yes I have a 2019 Rubicon automatic. So I guess if my Jeep gets to a point where it’s searching for gears a lot than its time to go up to 5.13’s?
It won't hunt for gears so much as you won't see 8th gear as much. I ran my 37's on the 4.10 gears for quite a while and found it to be more than enough for my needs and I carry a ton of gear. I've done videos where I talk about this and show me going up hills too. All I'm saying is rather than planning on spending a ton of money before you have any experience running 37's, get a feel for things first and then decide. Just trying to save you some cash.
Looking good!
Thank you :)
Hey, curious to know what offset the rims were for that particular build?
4.5" of back spacing.
would they have fit and not hit the 3 piece metal front bumper.. What would have been useful..
With 37's, I don't think so.
Great video! I am new to off-roading and just got a JL Sport. I was reading that the JL Sport has a gear ratio of 3.45. Do you think I would have to regear if I do a 2.5 inch lift with 35 inch tires? Also, do you think 35's would fit on a 2.5 in lift on a JL Sport without rubbing? Any advice would be greatly appreciated. Thank you!
Assuming you have an automatic, you should be fine with 35's and without the need to regear. You'll still have plenty of power. Also, so long as you install the correct bump stop extensions, you shouldn't have any rubbing issues with 2.5" of lift or at least, in terms of your fenders but depending on what wheels you run, you may have a slight rub at a full turn. Not really a big deal though and something you can correct by adjusting your steer stops.
@@wayalife Thank you so much for taking the time to answer my questions!! Can't wait to get lift and hit the trails!
Is there a way to contact you to discuss lift options? Just ordered a 2020 Rubicon and want to put 37’s on it. Thank you!
Yeah, you can find me on WAYALIFE.com
Hmph, I guess 3.5 is the the way to go or 4? 🙂 on a JL Rubicon do you need to do any reprogramming or Mods when lifting thanks love this channel!
Actually, I would say 3.5" at most especially being that most lift kits yield way more lift than is advertised. This is just a spacer lift and so we got exactly 2.5" of lift. 3" or 3.5" of actual lift at most would be good to prevent rubbing with 37s. You will need to calibrate your speedometer with bigger tires.
You may have already been asked this Eddie, but what is your average MPG's after putting the 37's on? Thanks.
Depends on how I drive. On the highway doing 75-80 MPH, about 14-15 MPG. Doing 55-65, about 18 MPH. Around town, maybe 13-14
Maybe a 3 inch lift or a half inch more on the bump stops or both might be a better idea what do you think?
A 3" lift is definitely a better fit for 37's if you don't want to deal with any rubbing and or trimming to mitigate them. If you want a lower stance which can be desirable for a lower center of gravity, this is an option as well.
What type of wheels are those? Look a lot like the canyon wheels that the grand Cherokee come with from factory.
KMC XD231 RG Beadlock Wheels.
Maybe I missed it but is this the mopar lift that gives the clearance for 37s?
No, this is the EVO 2.5" Boost Lift
Must be nice to have your own proving grounds not too far away from home to test out any new changes. LOL Many off road companies have to drive miles to test out new stuff. I'm thinking that property purchase wasn't by chance!!
LOL!! No, it was no accident that we chose to live where we live :)
Hey Eddie,
Whats the backspacing on your wheels? I am going to your old set up on my JL that you had on Moby (20X10 ATX slabs), and was wondering how different the backspacing is between those and your wheels. Love these videos, helping me decide on the set up for my jeep
The KMC XD231's have 4.75" of back spacing. The ATX Slabs have 3.5" of back spacing.
Shit, I may need to rethink my wheel choice. I'm going to be running the 38x15.5x20 Coopers and I think with a 3.5" backspace, that may stick out too far. Do you have any other recommendations for another beadlock?
Have you ever given the Chamber Pro II a look? They come in a 4" back spacing.
No, but I will now. Thank you.
We're running them on Moby now.
@Wayalife Would those tires have rubbed no lift on Jl 37s and inner-fenders removed with high line mod done to them what wheel setup is on it looks sweet
Without a lift, 37's would rub like crazy in multiple places even with the fender liners removed.
Wayalife that’s what I was afraid of I like the look of high line fenders without the inner fenders from (AAL) but afraid to look like monster truck with big lift l like as little lift and as big a tire as possible daily with ocasional off-road trips and Beach maybe what you recommend
I just purchased the same exact jeep yesterday. What is the exact width of those tires? Should I get a 3 inch lift. I want the same size tires but I do not want them rubbing.
If you don't want rubbing, you'll need to run a 3" lift and/or run taller bump stop extensions.
Do those 37" Cooper STT Pros produce any road noise or is it bearable?
Well sure, any mud terrain is gonna be louder than street tires but I don't think it's too bad. Toyo MT's might be quieter and Mud Grapplers are a LOT louder.
I wonder if there's a case for a higher set of rear fenders for this. IIRC, one of the Jeep concepts from the Easter Jeep Safari had them.
Rubicon model JL Wranglers come with higher fenders. You couldn't do this with a Sport or Sahara.
Are Rubicon rear fenders also higher than on Sport / Sahara? The front fenders are visibly higher, but the rear fenders appear to be similarly placed to the Sport / Sahara, or not as high.
The concept I was talking about is the Sandstorm one.
To the best of my knowledge, the Rubicon rear fenders are higher as well. You might want to ask this question over on www.JLWRANGLER.com as we do have certain members who are a lot more in the know than me.
Thanks for the reply!
And Yet another reason I am loving the JL. That is very minor trimming to fit 37's and low lift. My JK with 2.5 inches ended up with alot of trimming and no fender liners. Thank you for the info! Are you getting rock chips on the rear fenders yet?
Oh yeah, the rear fenders are getting all beat up but we knew that was coming especially with the bigger tires.
Eddie, I’m about to buy a RK 2.5 lift for my JLU Rubicon. I will also be buying aftermarket wheels. I plan to go with 37” Cooper SST Pro but can’t decide between 12.50s and 13.50s. Do you have an opinion on the the tire width? My Jeep is not a daily drive and I just run mild trails. Thanks
I suppose it depends on what wheels you'll be running. If you decide to go with 13.50, you'll want a wheel with less back spacing. With that said, most people run 12.50.
Thanks
Can I put 37s on a JL 2 Dr with a Ruff country 2.5 in lift and have the same minimal rubbing ?
I suppose it depends on what 37's you'll be running being that not all measure out the same as well as what wheels you'll be running as the amount of back spacing on them will make a difference as well.
What made you decide to go with 37s as opposed to 40s like your JK?
LOL - we don't have 1-ton axles under our JL like we do on our JK
I have a dumb question..I thought the Rubicon option came with a 2 lift from factory? So if that is the case, is this lift a gross 4 1/2” total? Or net 1/2” increase?
I suppose it depends if you're trying to compare it with a Sport or Sahara.
Yes. Compared to either
Do you run discover on all your jeeps
What happens when you get in the mud and gravel and you have these clearance issues again? It seems like any damage that happens is worth just doing 35’s.
It seems like that's exactly what YOU should do :)
Wayalife I love your stuff and videos. I’m old school and drive an FJ40.
Lol at the spare tire 😂
LOL donut..
What about the computer and speedometer configuration when adding larger tires for the JL? Those of us with RAMs and JKs can use the AEV procal. I assume this is a task that requires dealership assistance with the JL.
Unlike the JK before, you can now take your JL to the dealership and they can recalibrate your speedo. You purchase what is called an MVP and it is good for up to 2 calibrations. This includes new gear ratio and tire size changes.
where did you get the windshield banner? link please?
Right here: www.wayalife.com/store/proddetail.php?prod=DECAL-JL-WINDSHIELD
I’m about to get a 2.5” lift on my JLU sport and then get 37s. Anyone know what mpg I’m looking at?
Depending how you drive, you should still see pretty decent MPG for a Jeep. On the highway doing 75-80 MPH, we're still seeing about 15-17 MPG. This as opposed to 8-10 MPG on our JK before.
Impressive how little it took to throw 37's on there and make it work. Looks like that drivers side front tire is barely clearing.
Being that what you're seeing is at a full stuff, that's all it needs to do.
Did you change the axle in the Rubicon to put 37 tire
No. We will continue using the factory axles until or unless they need to be replaced. So far, they're holding up just fine.
Nice that it only took simple fixes. Looks great on the rocks!
Thanks and yes, the fixes were simple and FREE :)
Hey Eddie, love the videos. I also know you care a lot about the video quality. I wanted to see if you were aware of the high pitched tone that I think one of your mics is created. I’ve heard it in a number of recent videos, it’s constant throughout the video and sounds like it oscillates with the gain. Anyways, just wanted to bring it to your attention. Keep up the good work
Well that sucks that you're hearing a tone as neither Cindy or I can hear it. Of all the thousands upon thousands of people who've watched our videos, you are only the 2nd person who's ever mentioned it to us and we will try to look into it.
Wayalife well that sure is strange. I checked both on my tv and in the UA-cam app and I can hear it. Can actually hear it more predominantly on iPhone. I’m a video editor and photographer as well, so this space isn’t foreign to me. Let me look at the audio waves and see if I can find the frequency...or video a video that you’ve done where I don’t hear the tone. Maybe then you can compare the gear used in both videos.
Wayalife so, I can hear it in the last lift instal video, but it’s not present in the wheel mounting video. It really sounds like wireless interference. Are you using a wireless lav in any of these videos?
We really appreciate you bring this to our attention. Looking at the audio visually, we can see what you're probably hearing. Apparently, it's a problem with one of the cameras we're using. It's a real bummer being that we used it in Moab and so all the footage from it will still have it.
Wayalife ah that’s a bummer. Well, good luck. I sent you an Instagram video to show where the freq was occurring. You may be able to isolate and remove the frequency since it seems to ramp from 8000 to 10000hz. But I’ll let you guys decide if it’s worth the work. Keep the great videos coming. Love the JL stuff. Cheers!
Do you think that if the 2 piece fender get high lined and the bottom removed as well as aftermarket sheet metal liner 38s will be a problem
I suppose it depends on how much lift you're running and what kind of back spacing you're running.
Say similar to this but with 2.5 mopar lift, similar backspace wheel, Milestar 38s
If not I guess I’d have to go Metalcloak 3.5 and avoid the rubbing just wanted something to stuff 38s into a minimal lift low center of gravity setup
The Mopar 2.5" lift will give you more like 3" of lift. Not really a fan of china tires but of course, to each their own. Still, you're real issue would be back spacing of your wheels and not necessarily tire size.
Hey Eddie I love your videos man it made me go get a JL rubicon! Haha...I want to put 37’s on it did you have to do anything to your breaks or gears to run them ?
LOL!! The JL brakes are a HUGE improvement over the JK and no upgrade was needed. Also, unlike the JK before, the new 8-speed automatic transmission is awesome and no regearing was necessary to run 37's.
Are you going to be regearing for those 37's?
While we had assumed we would need to, we have so far found that the all new 8-speed auto does a great job of pushing our 37's along and honestly, we feel no need to re-gear or at least, not at this time. IF we ever decide to re-gear, we won't be going with 5.13 like we would have on our JK's. At most, we might go with 4.88 but really, even that might be too much.
Thank u
You bet :)
Would you say with a 3.5” lift, you wouldn’t have any rubbing at all?
Assuming you have a complete kit and are running wheels with the right amount of back spacing, yes.
Hows the ride quality compared to the jk with the dtd?
LOL!! There's no comparing this to a DTD.
what if you remove stock fencers?
What if. Seems like a lot of trouble just to address something so minor.
When are xd60's coming or v8 swap?
LOL!! They'll come when they're needed. So far, everything is still holding up :)
Should you have done a 3 inch lift instead to have avoided the rubbing?
More lift doesn't necessarily mean you won't still rub. Taller bump stop extensions alone would have addressed the negligible rubbing we we seeing.
Wayalife thanks for the reply and information
What did you end up doing with rear tire rub???
Umm, maybe watch the video? LOL
Are these 37/12.50 or 13.50 and what size rim 17 or 18.
Thank you
These are 13.50 on 17" wheels
@@wayalife Thank-you for your quick response.
If you were to run 35's instead of 37's none of these points of contact would be an issue or even exist .. Great info and video thanks ..
This is correct. In fact, you can run 35's just fine with the 2" Mopar lift. But then, we were wanting to run 37's.
So would you say the mopar 2inch lift isn't enough for 37s?
I think it's pretty evident in this video. I think it's also the reason why Mopar states their kit is made for 35" tires.
wowzer they just came out and you already put a lift and 37 inch tires
Even better, we were able to do this with just a 2.5" coil spacer lift.
Wayalife wow lol.
so does the stock rubicon jl and its articulation provide more than a stock rubicon jk ?
From what we have seen, yes.
I wonder if 3” will clear it all
You still need to do something about the rear fender liner.
37s with a 2.5" lift should still be good for mudding right? I dont rock climb
Oh yeah, even if you did play on the rocks, it'd do well.
@@wayalife alright just didnt really look that way in the video 😂 about to get after market fenders and a bumper anyway so should be good. Thanks for the quick reply
@@wayalife am i gonna need dana 44 axles?
Hard to say. Guess it depends on how hard you play.
Why did you not put a 3.5 inch lift on?
We filmed this quite some time ago and back then, there were no 3.5" kits available.
Did you regear with 37s?
Not at the time of this video. And really, there isn't a need for it if you have 4.10 gears and an 8-speed auto.
What was the gearing/lift on the JL at the time of filming?
At the time of this video, we were running an EVO 2.5" lift and with factory 4.10 gears.
Wayalife ... and did you re-gear? I’ve got an AEV 2.5 on the way for my JLUR and was thinking 37s would be in “regear” territory.
If you have a Rubicon with 4.10 gears and the all new 8-speed automatic transmission, there is NO need to re-gear with just 37's.
@@wayalife - Thank you so much.
My plan is now to stay on 35s w/ the AEV lift, then get 37s on the next tire set.
Thank you again for the great content and advice.
w/4.10 what about regearing if running the new trail grappler 38's your running@@wayalife
What wheel offset are you running?
In this video, you're looking at KMC XD231's with 4.5" of back spacing.
@@wayalife the video description says 4.75. Which is it? And would a slightly different backspace alleviate the slight rubs? What is the ideal bs for 37 on a JLUR with 2.5 lift?
How many inches of bumpstop do you have here?
You always need to run about as much bump stop extension as you have lift.
I didn’t think you would answer being such an old video but thanks! So I have the metal cloak game changer 2.5. With the American adventure labs High line fender and inners on 37. Would you recommend 2 or 3 bumpstops
@@ClevelandWHAT Honestly, you should work off of the actual amount of lift your kit gave you and if it came with new springs (as opposed to spacers), you more than likely got at least 3" of lift out of it. The real purpose of bump stop extensions is to help prevent the over compression of your coils - as in, they squash down to the point where they no longer return to their original height. That being said, IF your kit really did give you just 2.5" of lift or even a bit less, going 2" should be okay.
So I guess a 4 inch lift is necessary for no rubbing on 37s?
LOL!! The only thing that was rubbing was some plastic and I was able to fix it in minutes and for FREE. I personally couldn't see why anyone would install a significantly taller lift and one that would not only cost more but would also throw your center of gravity even more off just to address something so minor. If anything, installing slightly taller bump stop extensions would be the better way to go but even that seems silly to me.
Sir,
I’m going to put on 17 x 9 wheels, with 37x12.50.17 tires....
Will I need wheel spacers or will it clear?
If you're asking if they'll rub anything for daily driving, it'll depend on how much back spacing your wheels have. If you're asking in regards to rubbing your fenders at a full flex, it'll depend on how much lift you're running and how tall the bump stop extensions you have.
Wayalife 4.75” Backspace, -6 mil offset, 2.5” lift with shock extensions
You should be good to go.
Wayalife excellent. Thanks for the quick reply.
It looks like 2.5 is not enough.
Since you are making a budget mod you should consider a body lift?
Cheers
I fail to see why 2.5" is not enough. If you've watched the video, you would see that there was only MINOR rubbing of the plastic fender liners and not only did it take minutes to address, the fix was FREE.
But you left coloured body metal exposed to road debris. It will get chipped and start rusting in no time.
That hasn't been the case with my 2 JK's but hey, that's just been my experience.
That’s some experience if that was me I cut that shit lol
