I've tried to put together a list of many of the parts and tools that I use on my Amazon storefront:
www.amazon.com/shop/casey_250
Thank you for this video. I have 35s and I want my 37s back . I hear from so many people on what I need but this made sense what you said. No one never mentioned brakes.
6. On the list, for those who are running 3.5inch and up of lift. Driveshaft upgrade is also recommended for better clearance and drive train alignment, aftermarket driveshaft options are available out there.
Casey thanks for mentioning larger brakes with 37's I did mine recently and honestly I wish it would have been the first thing I did. People don't realize the weight we add the height changes stopping angles and the tire rotations differences. I did the G2 it was cost effective and at 1hr garage install (I have access to a lift) but very easy. I asked a guy in the business 30 years why don't people do life saving Mods his answer is because you can not see them. Bravo for talking bout it!!!!!
No doubt! When I first put 37s on I was shocked how much my braking changed!
Very helpful. Thanks for all the information!
Hey you dont need to waste any time responding to this but just wanted to say keep the videos coming man!!!
Never a waste of time to stop in and thank those to who took time to watch my videos! Thanks for taking a moment to leave a comment, it means a lot to hear from viewers!
Great channel man. Subbed!
Thank you! I am a fan of your channel too!!
Very detailed good job
Just found your channel! I have a stock, 2014, 2-door, Freedom Edition JK that I'm itching to have lifted. CHEERS!
Do it! Then bigger tires.. then.. then. Hahah.
Ran 37s on factory suspension with no fenders and trimmed the rear pinch weld for awhile until i just got my rock krawler lift put on last week...which now i have found a bolt in my front passenger side tire so ordering a new tire this week
Love the no fender look. Wouldn't last long on the road though before being pulled over in this area lol.
Very informative! Thanks
Your very welcome.
Great video. Nice jeep
New subscriber here. I recently just got interested in off roading and definitely want to purchase a jeep wrangler.
My biggest concern was buying and upgrading a sport/Sahara vs buying a rubicon.
I don't plan on rock crawling much but I do plan on hitting muddy terrain.
I live in Georgia here in the USA.
Welcome to the channel!!
Great info !
Thanks for watching and I am glad it helped!
When is the comparison video coming out? Just wondering, because I’m trying to figure out what gears I’m going to run for 35/37inch and still get a little bit of mpgs and power out of it. Right now I’m on 33s with stock 3.21 and 5th is more like an overdrive and hardly ever get in to 6th without having to drop back down just at the sight of a hill.
Some good advice here. Even with a Dana 44 up front you want to be careful running 37's and as stated in the video you would want to add some strength to the axle with C gussets and possibly a truss. another thing to consider is the actual tire itself, The BFG tires run small so you may be able to get away with less running BFG's vs something like Maxxis or Nitto that are a true to size tire. Keep wheeling!
Thanks! - There is also a big difference in weight between tires. Toyos run a lot heavier then Procomps. The KM2's are in the middle that I run. When on the Jeep and under weight they are 35.5inchs at 28psi (37x12 tires). I am looking at going to a 38inch tire for my next set but am worried I won't be allowed into Jeep Jamboree even though they measure 36.5inch with a 38iinch tire label.
@@Casey250 Hmm that could be a problem. I've thought about going to 38's myself. What axle shafts are you running up front? I think with all the other upgrades that might be the ultimate breaking point.
@@Casey250 Jeep Jamboree max is 40", as in 40" is OK. Need Dana60/80 for that tho. I'm thing of Dana60/80 on 43's with beadlocks and getting 5 @ 40's for Jamboree runs.
Great tips
That was a good video on that .the regear video would be a good one to do for a lot of jeep people that are looking to do there jeep like me mine a 2018 JKU stock Sahara and mine I'm thinking of going with 33 on it and 2.5 lift for some off road as it my daily driver and I live in Ontario Canada so keep up with the great video 🖒
Thanks and I will do a gearing one. Its kind of boring but lots to talk about walking through all the things to consider and different variables.
@@Casey250 so when you don't use your skyjack that good to know as a new jeep owner we think that we need this and that because it looks good on the jeep but in reality we don't so the tips that you give us helps so thx
You can add a AEV platform to your factory jack for extra height. I also carry a small bottle jack as well for tighter situation and it extends quite high... However ive never use that either lol
Was watching you vlig on 40s, then clicked to this one. I'm on 35s. I'm planning on going to 37s
37s are a great size. Mods to support them aren't crazy expensive and you get a little more clearance then a 35.
I have a Jku Sport with a 4 inch lift and planning on running 37’s, but I have a Dana 30, can’t I reinforce it or should I go with a Dana 44 axle and what have you done to the rear axle?
On point! Enjoyed the advice. I'd love to run 37's the CORRECT way... But I'll keep the 35's for a while. 😅 When you talked about the tuner... What mount/display are you running there?
The tuner is on the suction cup mount it comes with. The phone and tablet mounts I use are on my Amazon storefront - www.amazon.com/shop/casey_250
Good job on vid
Thanks!!
Great vid
Thank you for watching!
Solid video subscribed!
Good video, and if I recall you may be getting a new Jeep at some point? If so I hope you are going to post the whole build in full detail as it progresses.
I wish I started making videos when I started this build, as it was bone stock! I am really considering a Gladiator but there are a few influencing factors still up in the air. It sure would be a lot of fun to build!
Casey_250 watching your process of building a Gladiator would be awesome! Hopefully some of those circumstances resolve themselves! Keep up the good work! I get excited about building my 97 XJ Cherokee Sport after every one of your videos! It won’t be a beast like yours but it won’t be a pavement princess either lol. We off road races for quite a few years with the Nissan emblem up front with great success but very excited about now being in team OllllO 😁
All builds are fun, I eventually want to branch out beyond just Jeeps. I think the greatest barrier to the Gladiator is not knowing the price, especially what it will land at here in Canada. I have a good idea where it will be. I think if I build a Gladiator it won't be as extreme, and i'd like to have it for road trips to various Jeep events I am planning. 2020 i'd like to attend as many as I can, and long trips in my JK are very tiring at highwayspeeds because it... just doesn't like the highway a ton lol.
Casey_250 I have built a few trucks, lots of diesel performance stuff. Back in the day I built an 86 Datsun 4x4 that was a wonderful off road truck I took to Crows Nest Pass a lot and did serious wheeling with...Then an 89 that I did a mild build on and still wheeled it a fair amount...after that it was all about big street hp and I was also bitten hard by the diesel bug! I still focus on diesel but I’m really looking forward to making a nice off road adventure truck with this Jeep.
Whether it’s a Jeep or not, I’ll still follow your channel and see what you do next...I’m a gear head so I know I’ll enjoy it lol
Im running

Rim 26
On a jeep jk 2017 unlimited sport what’s the best option for it on axle
Great advice Casey. I have 35s and still planning to go with the big brakes. What was the cost? Do you think using your own calipers was a good decision vs changing the whole set up?
Price is always tough for me to approx, US pricing is always lower then Canadian. I think it was around $900 or $1000cdn. As for calipers, I reused my oem ones with the Dynatrac kit. My Jeep as a lot of miles on it, so I replaced all the calipers at the same time as I had 2 seized ones. If your calipers are fresh then there is no need. The Dynatrac kit supplies pads as well, but they are oem sized (different material) so if you ever need pads in the future you don't HAVE to go back to Dynatrac.
Thanks for your reply.
I just subscribed 🙏🙏
WELCOME TO THE FAMILY!
Also to be noted that if you do not use a programmer for a re gear it can cause your Jeep to go into limp mode.
RickN'Jeep only on automatic transmission
Trendy nitto lol km3 r the best but they don’t look as cool - but we wheel form or function --I pick FUNCTION
What if you put 37s on your jeep but are NOT going off roading with it, would this advice stay the same or should I be looking at a different Axel set up to just be safer and put less strain on my trans? Newbie here.. lol thanks!
I would still want to upgrade brakes as that is mostly an onroad mod and a safety one.
are those the poison spyder fenders? Jeep looks good really like the trail scales
They are EVO fenders. I could always see about doing a set of Bearded Jeeper Trail Scales up ;)
Casey_250 you make those trail scales? That would be awesome
have you thought about installing twin wire on passenger and driver to deflect the branches? what are those things called?
I have, but I don't find them overly effective.
@@Casey250would a protective film on the window help with that? like for a phone shield... I don't know.. just throwing out ideas
There are lexan windows on the market that are highly crack and scratch resistant.
Hello Casey, I am KC! Dude, can you help me? 4 questions for you....I have a 2015 JK, I acquired an AEV Dual Sport RS , 3.5" lift with Bilstien 5600s. It rides hard as hell. I also need this to get to work. It is on 35's right now. (with 21" rims) only leaving me 6" of rubber. 1. Will new rim/tires alone solve my problems? Do I need to get new coils? Not sure if I love the Bielstiens or not. How long do shocks last? 2. Thinking about FManx bead lock rims with 38" Patagonia tires. Will 3-1/2" lift clear those tires? 3. I have 4.1 ratio and want to buy the dyna axel with 5.1 assembled. Do I need to do anything to my rear axel? 4. I dont see anyone talking about mufflers. where do they go to avoid the crunch? Last... I want the hydraulic assist steering. thanks to you...Love that. thanks
Not Casey of course but have built many jeeps...
1. May not solve all the problems but will definitely make a huge difference!
2. Yes with flat fenders a little bit of trimming and correct bump stops
3. Any time you regear one axle you need to regear the other with matching ratios. 5:13 is a good ratio 👌
4. If you have aftermarket drive shafts you will not (should not hit the exhaust)
Also they have alot of high clearance muffler options.
I’ve got a question for you... I’ve got a JKU ( non-rubicon) being built as I write this. It is on big Spyderlocks and 37” X-MTs. We decided to truss and c-gusset, new Adams shafts, lockers, sleeves and regear with 4:88. The shop owner says that there isn’t a need for new axle shafts as the built D-30s hold up well. I hear you on the brakes and will need to address it. What do you think my weak spots in the driveline are? Some have said axle shafts. I’d agree because that’s the only thing not replaced.
Ring and pinion on a d30 is absolutely the weakest point when running larger tires. There is no upgrade to do other then upgrade the entire axle.
Casey 250 can I borrow like $13k USD for the Prorock D-60 I’ve been itching for?
Haha.
Are you running a 3.5inch long arm lift? And if so did you see and increased performance off road over a short/mid arm? And lastly if you are running a short/mid arm does the Jeep wonder on the highway a lot more over stock?
Short arm from Rock Krawler. Its very sturdy at 3.5inch. The higher pinion angle prorock 44 helped but it was good before the axle.
@@Casey250 Awesome, Thank you.
Nice video! So what do you think about the teraflex Tera 30 axle? I have a stock dana30 and don't want to change everything to go with a 44. European prices are crazy for the jeep stuff...
Honestly the ring and pinion is the weak point. I see no point in upgrading to a housing with the small ring and pinion. Either go up to a 44, or install some C gussets on your existing housing to protect it and take it easy to try to not brake your 30 and just accept that that may be something that you have to upgrade when it fails.
@@Casey250 I'm aware of this problem, if it breaks its going to be upgraded to aftermarket stuff anyway, it would be a cheap upgrade before something is broken. It's said that the ring and pinion are breaking because of the torsion of the diff housing and with stronger housing it will hold a lot more. But I don't know...
Ive never heard anything about the housing being the problem. The dana 30 and 44 housings are very very similar, its the ring and pinion size that is the issue. Good luck with your build, always happy yo help if you have any questions!
@@Casey250 I was told this. Thanks for the answers!
If I have a dana 30 do I need to get a new housing and regear it or do you think I can just get away with regearing it
On 37inch tire my advice is upgrade the axle to a larger ring and pinion. Such as a prorock 44.
Hey casey if i want to upgrade my front axle should i also upgrade the rear one?
Not necessarily but if your going with tons (like a prorock 60 up front you will upgrade the rear as well)
You video was in my feed, and Your video is very informative for people that will transition to 37
s. I wanted to know did you do your transition all at once, or in phases, if so what would be the top 5 that must be done in the beginning. I have a 2014 Jk Sport, and I trek to the Smokey's once a year as a retreat, but my JK is a my daily driver. Thank You.
I originally built my Rubicon and stuffed 37's on it... then broke the axle, and then it all started to escalate. My Jeep was build over about 3yrs as I either broke stuff or wanted better performing parts such as bigger brakes. Top 5 things for first mods or 37's? If 37s, this video covers it, if first mods? I should make a video about that!! It would be lift, tires & beadlocks, winch, gps, tire carrier, tuner, swap bar disconnects. I need to think a little more but that sounds about right.
What beadlock rims are you running on your jeep?
Trail ready
Which Fenders do you have here on your JK?
Evo mfg
casey im looking at this chart what does the numbers mean example say 1969
Which chart?
What Castor Angle are you running with that lift?
Thanks for the question, I honestly can't remember where it is at as it has been a few years since doing anything with. I have the Dynatrac ProRock 44 with the high lift option and adjustable control arms, and my Jeep handles very nice and feels quite stable at all speeds.
What would you recommend? Automatic or standard?
While I am in the #savethemanual club and my Vette is manual, I prefer an auto for offroading. Many times I have been able to climb steep inclines that require a run, such as sand dunes, where my auto would allow me to drop down in gears with out loosing momentum, and the manual Jeeps could not. As well, it is much much easier for me to vlog and run a camera with an auto. There isn't anything wrong with picking a manual either but that just has been my experience and my preference is an auto.
Would running 35s require this much extra? Is the difference from 35 to 37s that significant?
It can be. You can get away with less miss for 35s I think.
I have been running 35s for a year with only a 3.5 inch lift. So for so good!
How did you bend your front d44?
While I wasn't vlogging back then, I made a video telling my story - ua-cam.com/video/C66LDQ2-OMg/v-deo.html
Hi amigo limited straps not nesesary
U should think ab limb risers going through that heavy brush
I find they don't make much difference. At slow speeds the branches don't hit the window hard enough to break it (or haven't in 3 years of wheeling). I did put some special film (Trail Scales material in clear) on my A pillars to protect them from getting dinged up. I also really don't like the look of limb risers lol.
@@Casey250 gotcha. Thanks for the info. Didnt know all that about the film
Hi ,how much pis air you 37"tires
Usually 8psi or so
Casey 250 even when driving on the freeway?
I can put 37
In i lift my jeep 2.5?
With some trimming
Thank you 🙏
👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
Lol 44 is not much stronger than a d30 same tubes and c's . I hate to tell you this but your Ruby front axle is a half-assed 44 congratulations
Just found your channel. New subscriber. I'm running 37s on my jk as well. Not as built as yours but I have a tour video on my page if you want to check it out
Welcome to the channel - I will check yours out!
Just FYI, your brake upgrade did nothing for you. Changing out the rotors only, means the only thing you've done is provide better heat dissipation. So if "heat" is your issue (unlikely), then the upgrade is fine. However stopping power is provided by friction and the only way to create more friction is to either: Replace your pads with pads that have more bite OR increase the "surface area" and user bigger calipers & pads.
The larger rotors are great for better heat mgt, but should have been coupled with upgraded calipers. Also, moving to calipers with more pistons could apply better pressure more evenly across the pad (assuming the upgrade didn't upset your brake bias).
So just FYI, probably not a good idea to champion larger rotors only as providing better stopping power, they don't.
Thanks for the comment but that is not correct. The stopping distance is absolutely improved and Wayalife did a video measuring it. Larger rotors and moving the calipers out is the same physics as using a longer beaker bar to crack a nut. The Dynatrac ProGrips brakes are substantially better then stock. I can't speak for other kits but anyone that moves the caliper out with a larger roter would improve braking. If the caliper wasn't moved out then I agree there would not be a change, but you also wouldn't be able to add a larger diameter rotor.
@@Casey250 You are correct, that is my fault, i forgot about the moved caliper. With the larger caliper, rotational speed is decreased on the outer diameter and so the pad "should" be able to be more effective.
Actually I’m gonna have to disagree with you about the truss, local off-road shops around me have quoted about $500 out the door for an evo truss and c gussets. That’s a lot cheaper than new housing
Sounds like a great deal. Make sure the shop is spending the time to complete the welding process properly with out bending the housing. The only absolute way ive researched is to disassemble the housing and run a thick rod from end to end. Ive spoken to several shops and the only ones thst guarentee no bending, want it disassembled. There are always cheaper and easier ways to do things but they carry certain risks. Likewise, completing my list of things I feel are important is regearing as well. I just don't see the point of dismantling the axle, to pay a bunch of money in welding and labor versus putting that towards a better housing and reassembly. These are my opinions though, there is always different ways and opinions. A truss can also create clearance issues with your engines oil pan so make sure your bump stops are set to accommodate for that so you don't end up with an oil leak. At the end of the day, your still running a stock housing that you've spent a bunch of money on, has new disadvantages, and has less strength of an after market housing.
Also, your stock dana 44 housing will have a resale value, further reducing the cost of your after market solution.
Collin Campbell welding mild steel to casting may crack if not done right. I welded front and rear truss kits with c gussets and had no problems. 4.5 lift 37” tires 5.38 gears manual transmission Dana 44 front and rear RCV axle shafts in front.
Hay Casey! Please would you stop putting a red border on your thumb nails, it makes it hard to see if I have watched a video or not! Cheers mate! 🇦🇺🇦🇺
Ha, I never thought of that. Thanks for pointing that out!!
