seeking help with 4" lift

Recently purchased an 08 4 dr jeep wrangler unlimited x sport. Im wanting to purchase a 4" suspention lift and run 35x12.5 on it. Questions I have. 1: With a 4"lift will I need to do any other modifications? 2: Can I run 16 inch wheels? 3: Thoughts on a rough country lifts?

Read this and Pluke's post within.

That being said..., you DO NOT need 4" to run 35's. One of the great things about the JK.

Here's mine with 2.5" plus 1" rear spacers. Actually settled over 3"

Do not go cheap on a lift. Read/look through the lift sticky atop the JK section.
Do your homework, trust me

^^^This.

Seems like this comes up all the time...peeps arbitrarily deciding to throw unnecessarily high lifts and 35's on their JKs.


Some things to consider:


*Driveshaft: too high of an angle will eventually destroy the cv boot on your ds; if you see a stripe of grease on your undercarriage, you'll know it's time for a new one.


*Front axle: The D30 is weak; even if you have a Rubi, your c-gussets suck. If you plan on wheeling often with 35's, a sleeve & gusset job (or an HD front axle) would be a wise investment.


*Tire carrier: The stocker won't handle the weight of a 35" tire for long, especially if you pound your rig off-road. Eventually the welds in your tailgate will break. Look at something like the OR-FAB or TF HD tire carrier, or a rear bumper/tire carrier combo.


*Gearing: 35's will make your Jeep run like a dog, especially one with the 3.8L engine. High gear will be virtually worthless. Look into getting new gears – min 5.13 for an auto; 4.88 for a manual.

These guys nailed it.

Rough Country is cheap for a reason. Their springs sag over time and their lower priced kits are usually incomplete. They do have higher priced kits with control arms and shocks but then you are left with saggy Rough Country springs and horrible shocks.

I am at about 3.5" of lift with 35's and they look small to me, I am going 37's next, and my rear driveshaft just kicked the bucket. My front isn't too far behind. Also KBWWOLF brought regear and tire carrier for 35's, spot on. No one is saying don't do it but to get "the look" you want may end up costing a way more than you thought. If you have the budget fine, but don't cheap out on the suspension.

If you go 2.5" and 33's, you can pretty much keep stock driveshafts, stock control arms, stock tire carrier and your gearing will be tolerable. Go whichever way you want but do it right and be prepared to spend some $$ for bigger everything.

Yes you can run 16" wheels. I do. And if you di decide on a 4", a 4d is easier set up to handle it. You will need new front and rear driveshafts, upper and lower control arms that are adjustable as well as adjustable trac arms for front and rear. Also sleeve and gusset your front axle, regardless of 44 or 30. The advantage of a 4" lift, you will not need to trim your pinch seem and you will have gobs of articulation with 35's and larger if you regear and go that way later. You may want to consider custom radius arms also. A lift that large really is un necessary for your JKU, but each to there own. Expect upwards of 6k to do it right.

You can actually run 15" wheels if you want. We have em on our rubi. Fit for some brands is hard but it's entirely possible. And the tires were about $100 cheaper. Mickey t's for $265 at Walmart when we went 15".

Coming from someone who has a 4" lift and 37s... GO 2.5" and 33s!!! Save yourself a bunch of money - or spend it on other things. With bigger parts, come bigger problems with bigger price tags. Remember, ONE mod = FIVE more. So anything you do, you have to think five steps ahead.

I would still however at least gusset your 30 no matter how big you decide to go, the sleeves too but they are not as big of an issue if you stay at 33".

Thank you all for sharing your knowledge and experience. Looks like I will be going 3 or 2.5. I do not want the headache of buying and replacing all the other stuff. Thanks a bunch!
