I installed a Teraflex 3" lift (with all 8 adjustable arms) in my 2013 JKRU and followed TF's specs for control arm length.
Here are TF's specs for a 3" lift:
Front lowers: Driver - 23 7/8"; Pass 24 1/8" (factory front lowers are both 22 5/8") [TF wants the passenger side lower arm longer to eliminate pull to the right.]
Front uppers: Driver and Pass - 19 1/2" (factory front uppers are both 18 3/4")
Rear lowers: Driver and Pass - 20 3/8" (factory rear lowers are both 19 3/4")
Rear uppers: Driver and Pass - 18 3/8" (factory rear uppers are both 17 7/16")
When I set my passenger side front lower to 24 1/8, the axle was so far forward that the passenger side coil spring was touching the tip of the sway bar. So I cranked the adjuster back in so it was 23 7/8" to match the drivers side. The sway bar then cleared the coil spring by 1/4". I have been running the Jeep that way for about 2k highway miles and all is well, steering is fine, tracks straight, no bump steer or other problems. No off road yet.
I have recently read posts saying Teraflex's control arm specs are not correct, various lengths are mentioned all shorter than TF's specs. I also asked a local 4x4 shop and they said that they setup TF lower arms at 24.0".
I am in the process of installing EVO Plush Ride springs and might as well adjust the control arms while I am at it, if necessary.
So my question is what length should I set my control arms, especially the front arms? Are they too long now at 23 7/8" for the lowers and 19 1/2" for the uppers?
Thanks
