I am wanting to put 37's, I have read some about the super lift 4inch and it clams it will fit 37's. Any suggestions?

37's will fit with a 4" lift.

Whatever lift you pick, make sure it has adjustable control arms, and track bars. Anything less isnt enough to dial in your suspension properly. With a 2 door you really need it. In addition you'll need new driveshafts..


4" Fulltraction ultimate will fit your needs

Best would be if you have the money to go with the following

Teraflex Front and Rear adjustable control arms
Evo Coil Over Front
Currie Coils for Rear
JKS Front & Rear Track bars
Crown extended brake Lines

You will have the best setup and you will remember this

exactly! if you want to go 4" of lift and 37's, you really need to make sure that you budget for the addition of adjustable control arms, adjustable front track bar, track bar drop bracket, dropped pitman arm, longer brake lines and drive shafts.

i have run 37's with a full traction 4" ultimate lift and 1" body lift and i have also run them with a teraflex 4" lift and no additional body lift. both setups work great

I forgot about the pitman arm and drop brackets for the track bars...

Perhaps it's the TJ part of me showing, but it blows my mind that you need new driveshafts just for a 4" lift. Same with the adjustable control arms. It's kinda sickening that you gotta budget an extra $1200 just to go up 4 crummy inches.

its the CV driveshafts, they cant take that much angle., It pinches the bearings off.

on the 4 door you can get away with more lift, not on the 2 door.

you'll forgive me but, although you could get away with dropping your t-case on a tj and/or installing motor mounts, technically, you really should be installing an SYE and CV driveshaft with as little as 3" of lift on a TJ. this isn't cheap to do and it isn't easy to install an SYE. likewise, you only need to replace your rear driveshaft on a JK if you have a 2-door as the angle that it will be in after installing a 3" lift or more will be severe enough to leave your CV boot in a constant state of pinch. this will lead to it's premature failure and subsequently, the failuer of the joint itself. however, this doesn't happen over night and you still won't have vibes. as for up front, you only need to replace it after installing a 3" lift or more ONLY if you have an automatic. this is necessary as the spline shaft boot will catch your transmission when flexing and tear off. but, even at that, you can still drive with it in this condition for a long time. also, i think i should point out that a set of 1310 shafts can cost as little as $750-$800 and NOT $1200 and once again, if you have a 4-door, you only need to replace the front shaft. do you know how much it costs to buy an SYE, CV drive shaft and adjustable rear upper control arms on a TJ? because, that is what you really need on a TJ with 4" of lift.

Ive got over 5000 miles on my stock drivelines, 4" lift, and 37s with an auto.

All of the 4" lifts are good but some just need more parts added to be great.

I checked into drivelines and they were over $1000. Where can I find a good set for $750-$800?

if your front driveshaft does not have a torn boot, you are not getting an adequate amount of droop or you are not disconnecting your sway bar links when wheeling. any JK with 3" of lift or more and has long enough shocks/components to allow for more flex WILL cause your front drive shaft boot to catch on the auto tranny and tear. this is not a maybe - this is a WILL.

IIRC, teraflex 1310's run about $350-$400 each. of course, if you are looking at 1350's, they will be more.

EDIT: so you know, i double checked and 1310's are in fact about $500 each.
