The explanation we all wished was included with every lift kit ever! Thank you so much for putting this together in such a perfect form. I now know exactly where I should focus my efforts in fixing the constant wandering on my AEV 3.5 SC lift.
Thanks for the kind words! Solid axles aren't too complicated, and death wobble isn't *that* much of a mystery, but a lot of people just don't know where to look for the problems in the first place! Hope this helps in the future and you can get your Jeep feeling planted again! 😁 -Zach
Excellent tutorial on suspension and what lifting does to it. What is also interesting is how different companies address the issues related to the geometry challenges a lift kit presents.
finally a video about steering geometry without a lot of useless jibber jabber and you sounded like you actually knew what you were talking about.......thanks very much for AN INFORMATIVE VIDEO............WILL SUBSCRIBE..........
I’m on hear doing research for buddies. I drive a 4 runner but buds prefer jeeps. I need to know about their vehicle as much as mine. Just had a buddy with link issues. Thanks for this great informational video.
Great video. Your explanation was concise and informative. Extremely helpful. Is there a possibility that you can discuss the minimum needs necessary to run 35s or 37s to wheel off and on road. Lots of info out there and it's difficult to know what the essentials are to run safely.
Minimum on road - 2.5" lift for 35's. 3.5" lift for 37's. If you are going to be wheeling heavy you will want higher fenders or a taller lift with those tires sizes. Just be careful because anything over 4" and something your going to wheel your going to need new driveshafts sooner rather than later.
To piggy back on Jason's question: in your vast ET videos, which would demonstrate the type of terrain that needs the sway bars disconnected, as opposed to trails with with foot-deep puddles, bowling ball sized rocks, etc. (I have a 2.5" MOPAR lift, 35" tires.)
In addition to the driveshafts mentioned above, new axles and re-gearing are good ideas. 35" wheels will make quick work of the stock axles if you off-road with any regularity. Re-gearing depends on tire size and how you use your jeep. There are handy re-gearing charts you can look up that will show this. The real thing that needs to be understood is that going above a 2.5" lift or 33" tires involves doing a lot more upgrades in addition to the extra cost of the bigger tires and lift kit. Between upgrading the drive train and re-gearing, expect to spend around $3,200 on parts alone, and if you get everything done at a shop, labor will run you around $2,000 (this is why most wrangler owners who don't plan on much off-roading go with 2.5" lifts with 33" tires.....it's enough to look better than stock and doesn't require additional expensive upgrades).
Thank you so much for all the information in this video, extremely helpful as i’m dealing with really bad death wobble on my JLU ever since i installed the Mopar 2” lift kit! Def much more informed now with what i need to look into and possibly upgrade. Thanks again!!
Noob question here... Will my stock suspension be affected if I just put bigger tires (33-35)? Will I need to do ajustements to my suspension to avoid any damage/problem? Please keep making this video's they are really good and informative!!

It is very informative video, I am new to jeep and my question is if I install longer control arm is that means pushing the axle forward which i afraid the tire may rub against the bumper? I have 33” tire thanks
Adjustable lower control arms would simply bring your front axle back to where it was before the Jeep was lifted! It won't go any closer to your front bumper if adjusted properly. -Zach
So informative! I'm planning a 2.5" lift on a 2016 JKU. Do I need to replace the front and rear track bars? How much lateral shift will a 2.5" lift create?
You'll see your front axle be shifted to the side about an inch, honestly. I would highly recommend adding an adjustable front track bar to your Jeep along with adjustable front lower control arms to get your suspension back aligned! Your Jeep will handle much better also, they're great additions if you have room in your budget. -Zach
Excellent video! Very informative. I would rename the title to include "Front" suspension as very little (none?) of the rear geometry was discussed/explained, which is what I was searching for.
I just got the Rubicon express 2.5 in with monotube shocks lift kit. The kit mentioned no need to change drive shaft. Unlike other kits that say you need to change it. When i put the rubicon express lift if there more that i am gonna need to do or are the geometry components more of an issue when it comes to 3in and up kits?
Very good video! I have a 2021 4 door Jeep wrangler Rubicon can you please list a couple 3.5" complete lift kits that will cover everything that was mentioned in your video? So one doesn't have to worry about geometry issues at all?
Thanks for watching, and I absolutely can! The JKS kit below would be amazing when paired up with a set of adjustable lower control arms. Or if you want everything in one kit, you should check out the following ReadyLIFT and OldManEmu options! -Zach www.extremeterrain.com/jks-jeep-wrangler-j-rated-35-in-suspension-lift-kit-jspec-gas-shocks-jspec119k.html www.extremeterrain.com/old-man-emu-jeep-wrangler-25-35-inch-heavy-load-suspension-lift-kit-omejl4dhks.html www.extremeterrain.com/readylift-jeep-wrangler-350-inch-3-inch-terrain-flex-4-arm-lift-kit-falcon-21-shocks-69-6837.html
Great video, first time I’ve heard about keeping the trackbar and draglink parallel, totally makes sense. Have you driven that Jeep? There isn’t a spec of dirt anywhere.
Now that was some good information. Thank you. I want to put about a 2 1/2 inch lift on my TJ. Where can I go to find all the correct components I will need?
so i bought my jeep about 2 years ago and it came with a lift kit on it, only problem is is that I'm not sure what size it is, and whether it's a suspension or spacer lift. The time has come to buy new shocks, but I need to know what size shocks to buy. And to know that I need to know my lift size, or I can measure the shocks extended and collapsed, BUT it would make it 10x easier to shop buy lift size as oppose to shop buy shock length, how should I go about finding out what size lift I have?
I ordered my first Jeep, a '22 JLUR. It's due to arrive by the end of next week. I wanted a 2" lift and 35s until I watched this video. Now I wonder how much this is going to cost me to do it right?! Thanks for scaring me out of my large purchase!
Hey, Mike! This video wasn't made to scare you, only to make you aware how Jeep suspension geometry works and how lifts affect angles! You're getting a Rubicon, right? You'll be able to fit 35s on there right from the factory! 😁 -Zach
Hi.. I have a '99 XJ that wonders at highway soeed.. Everything has been replaced on the frontend and it still wonders.. Any advice on fixing the problem..? Thanks Joe..
Hey, Joey! Is your Jeep lifted at all? If so, it may be worth looking into an adjustable front track bar and adjustable front lower control arms to get your alignment where it needs to be. I'd also recommend checking your tires out, if they're overinflated or have irregular wear it can contribute to negative handling characteristics. Best of luck! -Zach
Hi. I jus buy a jk with a lift, the jeep have a very bad wandering feeling while driving. I replaced ball joints, new track bar. Shocks, steering box, but still having the same problem. You think a tide tie rod can cause wandering or fix the caster can be better..
If you haven't replaced the tie rod ends yet, I'd highly recommend it. That will really help tighten things up in your steering. If your lift doesn't have adjustable front lower control arms either, I'd recommend looking into them as well. They will allow you to adjust your caster, which will help your Jeep track straighter down the road and not wonder as much. - Zach
Thank you for the information I do have a question I have a 2018 jeep I put on a Rubicon steel bumper and a whiches the front in is no longer level you told me I need a 3/4 space to keep the front of the jeep level. When doing that do I need to change anything else or my suspension? Also I went on your site and I seen a rough country 0.75 Front leveling kit is that what I need to level it off
Nope! The only piece you'll need to install is the spacer itself. No other parts will be needed. The leveling kit you found sounds like it will work perfectly, just make sure its for your respected Jeep (JK or JL). -Zach
Ryan, I am thinking of installing a 1"or a 1 1/2 inch front coil spring spacer on a 2022 Wrangler JL., Just to level it. Do I need any other parts for my application? Thanks
Not really just for a 1" spacer! You could always look at adding an adjustable track bar to help keep your axle centered up front, but that can wait until you lift your Jeep higher if you don't have room in your budget. -Zach
Question, I recently put a 2.5 inch Rough Country lift kit on my 09' Jeep Jk with 33-inch tires. I also replaced the trackbar, drag link assembly and tie rod. I live in Brooklyn and mainly use this as my daily commuter. no off-roading. Is it necessary for me to replace my control arms and if so which ones do you recommend?
Not totally necessary, but definitely recommended! Adjustable front lower control arms are really all you need at 2.5" of lift, you'll notice an improved ride and handling with them for sure. You should check out this option from Freedom Off-Road! -Zach www.extremeterrain.com/freedom-off-road-jeep-wrangler-adjustable-front-lower-control-arms-for-0-65-in-lift-fo-j703fl-adj.html
Hello boss, I recently bought Jeep JL 2018, 78000 kms on it. It has 33’ tires, 2.5 inch skyjack lift kit. It makes clunk sound on slow big bumps mostly on the turns.My Drag link was having little play I have change it but still it makes the same sound. Technicians had taken a look on it but he was unable to find any thing.there’s nothing loose even. What can u suggest. Thnks
You'll want to check your tie rod end links, ball joints, control arm bushings and wheel bearings. Any one of those places can cause a "clunk" when worn out. -Zach
So if I have a stock JKU is there any reason I would not want a kit that includes all the discussed parts? It sounds like every part mentioned should be replaced to accommodate the lift.
As long as you have the budget and you're doing more than a simple 1.5 inch leveling kit, there is no reason whatsoever that you would not want a kit that includes new track bars, lower control arms, swaybar links, brake line extension, etc. The more components you replace to correct your geometry the better you Jeep will perform, ride on the road, and last overall through regular usage. There are plenty of great budget level systems out there, but you really get what you pay for. -Zach
My mopar 2" lift came with new control arms, springs, sway bar end links, bump stops and shocks. Everything else stayed the same. Must get an alignment afterwards. 2018 JLU Sahara
I have all these issues. Front axle is off center, major vibrations on the highway, Axles/tires arent centered when looking at the side of the Jeep. I put in 5.13 gear on stock axles along with 3.5 MetalCloak GameChanger (2012 JKU - Sahara), I'm sure that the new Yukon driveshaft isnt in the right angle as well. I need some work done to repair all of that. smdh.....
so my comment would be does someone make a fixed lower and upper control arm for strength? or if the new adjustables come with factory length specs to adjust correctly?
You can absolutely find fixed upper and lower control arms that are made stronger than factory! The vast majority will be for lifted applications though. The only options you'd be able to find for a stock Wrangler would be adjustable ones. -Zach
Rear control arms are going to effect your pinion angle and axle placement mainly, but will help your ride quality as well! If you're still using the stock control arms on a 4" lift, the angles of them are most likely pretty steep. -Zach
I put 33s BF a/t on my tj 02 4.0 with a RC 3.5 lift and I get a lot of vibration on the highway, pretty much over 50mph. All this right after the lift, all I hear is is a jeep and that's how they ride, BS!! before was absolutely fine and now feel lose and noisy. I was told with this kit didn't need any other parts or modifications, any ideas, suggestions or help please.
Vibration while driving after a lift kit is installed is most likely coming from your drive line. I'm not entirely sure what all was installed with that lift kit, but here's a little list of extra parts I highly recommend you look into. Adding them will really help your suspension geometry and the ride of your Jeep, along with solving the vibrations: A front adjustable track bar, front-lower and rear-upper control arms, a slip-yoke eliminator kit and a new rear double cardan driveshaft (this will go with the slip-yoke eliminator kit). If you need more assistance, please get in touch with our customer service team and we will be happy to help! -Zach
does anyone know the consequences of using the factory sway bar links with a lift? I've installed a 3.5" lift, but it did not come with front sway bar links (it included rear sway bar links oddly enough)
A lot of budget-oriented lift kits will give you a new set of rear sway bar links, then have you use your factory rear links in the front of your Jeep since they're naturally longer anyway and they'll accommodate the new lift height. If you have the room in your budget though, getting a set of new front swaybar links with disconnects is a good idea! Especially if your factory links are worn. -Zach
Looking for some help. I have 2015 JK with a AEV 2.5 in lift, correction brackets, Fox steering stabilizer, alignment done. Then added 35’s. I now have play in steering and slobby on highway speeds. Constantly keeping the Jeep in line. How can I fixed this issue? Any help would be greatly appreciative
I would check out your track bar, ball joints, front lower control arms, and tie-rod ends. Since all of those are wearable parts they may be worn just enough to cause loose steering now that you added the extra weight of 35s. If you don't already have one, an adjustable track bar may be a nice option to add to keep that front axle centered as well. Also, make sure those 35s aren't over-inflated because that can cause wondering in steering as well. Hope this helps! -Zach
ExtremeTerrain.com thank you for the quick response. I lowered the tire pressure down from 40 psi ( tire shop set it to 40) to 34 last night. Do you think that is a good psi? Gotta drive the Jeep today and test it. Thank you for the other information I appreciate it. Gonna look into a track bar.
34 psi should definitely have things running smoother! A lot of tire shops see "max psi" on the side of mud tires and think that they need to be filled that high for daily driving. I'd still recommend checking everything mentioned just to make sure you don't develop any shimmy in the future, and that adjustable track bar will really help things feel planted on the road. -Zach
Good information and well done video and explanations but for many the background music interferes with clearly hearing what you are saying. Please drop the extra unneeded music noise.
Yeahhhh at 4" of lift I would highly recommend looking into make sure you snag some aftermarket adjustable control arms, an adjustable track bar, and something to address your factory driveline angles (like a slip-yoke eliminator kit with a new rear driveshaft). Feel free to give us a call or email and we'll be able to get you taken care of when the time comes! -Zach
This would have been a little more helpful if you guys had highlighted the parts you were talking about when you were showing them onscreen. Love the rest tho!

What Mods are done to your Jeep's suspension?
As a Jeep newbie, this suspension video provided and excellent overview and was very informative!
Very grateful for this one-of-a-kind presentation with fantastic illustrations! This is exactly what I wanted to know about a jeep's suspension!
Thanks for watching! -Zach
The explanation we all wished was included with every lift kit ever! Thank you so much for putting this together in such a perfect form. I now know exactly where I should focus my efforts in fixing the constant wandering on my AEV 3.5 SC lift.
Thanks for the kind words! Solid axles aren't too complicated, and death wobble isn't *that* much of a mystery, but a lot of people just don't know where to look for the problems in the first place! Hope this helps in the future and you can get your Jeep feeling planted again! 😁 -Zach
Super helpful! Took tons of notes! This was extremely clear, logical, and thorough. I really appreciate ya’ll putting this together.

Excellent tutorial on suspension and what lifting does to it. What is also interesting is how different companies address the issues related to the geometry challenges a lift kit presents.
Chuck Marshall there’s more than one way to address it, but the important thing is that it’s addressed
Very nice explanation! I found it very helpful!

Perfect video and a must see for anyone interested in lifting their Jeep. Thank you!
Great video, super helpful for Jeep newbies! Saved me a ton of money by replacing only the necessary parts
Thanks for watching! -Zach
That was the best explanation video for lifts I’ve ever seen!!! Well done
Thanks for the love, Luke! We appreciate it! -Zach
Perfect guide for someone with not much knowledge
This is GOLD right here! Thanks ExtremeTerrain!!!
It really helps that you showed this on the same grey 2 door that I own.
Awesome video. I am fairly new to the 4 wheel drive scene and have been looking for something like this to explain how the suspension actually works.
I’m on hear doing research for buddies. I drive a 4 runner but buds prefer jeeps. I need to know about their vehicle as much as mine. Just had a buddy with link issues. Thanks for this great informational video.

Very articulate and informative I enjoyed the video very much I did not know nothing about that and it's very interesting thank you.
Thanks for watching! -Zach
Great info, very clear, I only would loose the loud music. You should have more views and subscribers. Cheers
Very informational. My question is about alignment. So is it ideal to get the toe and caster to factory spec?
Great information! Answered a lot of questions I've had about all these components
It is very informative video, I am new to jeep and my question is if I install longer control arm is that means pushing the axle forward which i afraid the tire may rub against the bumper? I have 33” tire thanks
Adjustable lower control arms would simply bring your front axle back to where it was before the Jeep was lifted! It won't go any closer to your front bumper if adjusted properly. -Zach

Great video, first time I’ve heard about keeping the trackbar and draglink parallel, totally makes sense. Have you driven that Jeep? There isn’t a spec of dirt anywhere.
So, if I were to purchase a 2.5" lift kit, it's recommended that I should purchase a kit that comes with control arms, track bar, drag link etc?
Muchas gracias por el vídeo. Saludos desde españa
Now that was some good information. Thank you. I want to put about a 2 1/2 inch lift on my TJ. Where can I go to find all the correct components I will need?
my rear track bar is rubbing against my rear passenger spring coil. should i shorten my rear control arms to pull my rear axle away from the spring?
Wonderful video! Great presentation to make this understandable to the general consumer, very educational!
Thanks for watching! We appreciate it! -Zach
so i bought my jeep about 2 years ago and it came with a lift kit on it, only problem is is that I'm not sure what size it is, and whether it's a suspension or spacer lift. The time has come to buy new shocks, but I need to know what size shocks to buy. And to know that I need to know my lift size, or I can measure the shocks extended and collapsed, BUT it would make it 10x easier to shop buy lift size as oppose to shop buy shock length, how should I go about finding out what size lift I have?

Nice video and fairly concise explanations
does the Rubicon control arm is long than the sport control arm ?
I’m pretty sure they are the same size. At least on the 2007-2018 models. Not sure about the new JL wranglers

Hello Extreme Terrain what type of jeep is this?
The Jeep in the video is a 2018 JL Wrangler!
Awesome! Well explained and easy to understand. Thank you!

Very lucid explanation. Much appreciated. The music is annoying, hope you'll cut it in future.
Thank you for such an informative video!! Please do more like these.

Thanks for watching and subscribing, William! We appreciate it! -Zach
thinking about getting the 2.0l turbo rubicon... do u think 37s with a 3 inch lift would be ok or would it be too strenuous for the 4 cylinder?
Poppa Sim you’ll be fine with the engine but the turbo will have a shorter life than the 3.6

Hey , any jl front adjustable track bar in stock?
Hello boss, I recently bought Jeep JL 2018, 78000 kms on it. It has 33’ tires, 2.5 inch skyjack lift kit. It makes clunk sound on slow big bumps mostly on the turns.My Drag link was having little play I have change it but still it makes the same sound. Technicians had taken a look on it but he was unable to find any thing.there’s nothing loose even. What can u suggest.
Thnks
You'll want to check your tie rod end links, ball joints, control arm bushings and wheel bearings. Any one of those places can cause a "clunk" when worn out. -Zach
Fantastic video
Thank you for watching! -Zach
Where can i get more i fo anout uou guys i need help in my jeep im new to this.
Very informative
Thanks for watching! -Zach
So if I have a stock JKU is there any reason I would not want a kit that includes all the discussed parts? It sounds like every part mentioned should be replaced to accommodate the lift.
As long as you have the budget and you're doing more than a simple 1.5 inch leveling kit, there is no reason whatsoever that you would not want a kit that includes new track bars, lower control arms, swaybar links, brake line extension, etc. The more components you replace to correct your geometry the better you Jeep will perform, ride on the road, and last overall through regular usage. There are plenty of great budget level systems out there, but you really get what you pay for. -Zach
Oh man... this is gonna be good...
for 2 inch lift it is necessary to change all this arms or bars ??? for JL
My mopar 2" lift came with new control arms, springs, sway bar end links, bump stops and shocks. Everything else stayed the same. Must get an alignment afterwards. 2018 JLU Sahara
I have all these issues. Front axle is off center, major vibrations on the highway, Axles/tires arent centered when looking at the side of the Jeep. I put in 5.13 gear on stock axles along with 3.5 MetalCloak GameChanger (2012 JKU - Sahara), I'm sure that the new Yukon driveshaft isnt in the right angle as well. I need some work done to repair all of that. smdh.....
Awesome video mate 🧉
Thanks for watching, Ed! -Zach
is this such a big concern for small lifts? 1.5"
so my comment would be does someone make a fixed lower and upper control arm for strength? or if the new adjustables come with factory length specs to adjust correctly?
You can absolutely find fixed upper and lower control arms that are made stronger than factory! The vast majority will be for lifted applications though. The only options you'd be able to find for a stock Wrangler would be adjustable ones. -Zach
Very good 👍🏽 information..
Thanks for watching!!
Great information! very helpful
Rear control arms ? Are they important to change for ride quality!? I have a 4 inch lift
Rear control arms are going to effect your pinion angle and axle placement mainly, but will help your ride quality as well! If you're still using the stock control arms on a 4" lift, the angles of them are most likely pretty steep. -Zach
Well I guess I need to be buying a set
I put 33s BF a/t on my tj 02 4.0 with a RC 3.5 lift and I get a lot of vibration on the highway, pretty much over 50mph. All this right after the lift, all I hear is is a jeep and that's how they ride, BS!! before was absolutely fine and now feel lose and noisy. I was told with this kit didn't need any other parts or modifications, any ideas, suggestions or help please.
Vibration while driving after a lift kit is installed is most likely coming from your drive line. I'm not entirely sure what all was installed with that lift kit, but here's a little list of extra parts I highly recommend you look into. Adding them will really help your suspension geometry and the ride of your Jeep, along with solving the vibrations: A front adjustable track bar, front-lower and rear-upper control arms, a slip-yoke eliminator kit and a new rear double cardan driveshaft (this will go with the slip-yoke eliminator kit). If you need more assistance, please get in touch with our customer service team and we will be happy to help! -Zach
Thanks for the help, I would have all this parts install and see what happens, hopefully fix my issues
Thanks again

does anyone know the consequences of using the factory sway bar links with a lift?
I've installed a 3.5" lift, but it did not come with front sway bar links (it included rear sway bar links oddly enough)
A lot of budget-oriented lift kits will give you a new set of rear sway bar links, then have you use your factory rear links in the front of your Jeep since they're naturally longer anyway and they'll accommodate the new lift height. If you have the room in your budget though, getting a set of new front swaybar links with disconnects is a good idea! Especially if your factory links are worn. -Zach
Nice JL Ryan
Great video! Thanks!
Looking for some help. I have 2015 JK with a AEV 2.5 in lift, correction brackets, Fox steering stabilizer, alignment done. Then added 35’s. I now have play in steering and slobby on highway speeds. Constantly keeping the Jeep in line. How can I fixed this issue? Any help would be greatly appreciative
I would check out your track bar, ball joints, front lower control arms, and tie-rod ends. Since all of those are wearable parts they may be worn just enough to cause loose steering now that you added the extra weight of 35s. If you don't already have one, an adjustable track bar may be a nice option to add to keep that front axle centered as well. Also, make sure those 35s aren't over-inflated because that can cause wondering in steering as well. Hope this helps! -Zach
ExtremeTerrain.com thank you for the quick response. I lowered the tire pressure down from 40 psi ( tire shop set it to 40) to 34 last night. Do you think that is a good psi? Gotta drive the Jeep today and test it. Thank you for the other information I appreciate it. Gonna look into a track bar.
34 psi should definitely have things running smoother! A lot of tire shops see "max psi" on the side of mud tires and think that they need to be filled that high for daily driving. I'd still recommend checking everything mentioned just to make sure you don't develop any shimmy in the future, and that adjustable track bar will really help things feel planted on the road. -Zach
ExtremeTerrain.com Will definitely look into the track bar. thanks for you time Zach!
So well done thanks.
Thanks for watching! -Zach
When are you gonna start modding that thing kid?
Good information and well done video and explanations but for many the background music interferes with clearly hearing what you are saying. Please drop the extra unneeded music noise.
Awesome information!!!!
Thanks for watching, Jerry! We appreciate the love! -Zach
awesome video!
Great info, thanks 🙏
Thanks for watching! -Zach
Thank You...
Thanks for watching! -Zach
Thanks for the info!
damn, this video is an A plus BIG TIME !!!!!!
Thank you for the feedback! -Zach
Wow that really helped
Very Interesting!
I guess I shouldn't go with just shocks and springs... 4inch TJ lift just got a lot more expensive
Yeahhhh at 4" of lift I would highly recommend looking into make sure you snag some aftermarket adjustable control arms, an adjustable track bar, and something to address your factory driveline angles (like a slip-yoke eliminator kit with a new rear driveshaft). Feel free to give us a call or email and we'll be able to get you taken care of when the time comes! -Zach
So good
Didn’t mention about driveshafts.
This would have been a little more helpful if you guys had highlighted the parts you were talking about when you were showing them onscreen. Love the rest tho!
He pointed directly to them.
Great video, but please turn down that music

I believe my brand new, stock JL began to develop bump steer at around 6000 miles. SUCKS!
Excellent Video! Kill the background music its distracting
The music why
