After long waiting next week I will install the following:

- TF 2.5" Lift Kit w/shocks
- TF FlexArms (front lower)
- JKS Front & Rear Adj. Trackbar + Rear TB Brace

Today I took a look at the Control Arm, very massive!
I then set the length as stated in the supplied instruction. For a 3" lift, to reach 4.5° Castor, the following value are suggested:

Driver side: 23"-1/8
Passenger side: 23"-1/4
The difference is basically a full turn of the joint.

The instruction say that the length difference is needed to "eliminate the tendency of the JK's to pull to the right".

I would like to know the reason of this tendency and if you agree/suggest to use control arms of different length.

Thanking in advance for any advice.

 

Mine had no pull to the right with 35's, it got a pull with the 37's prolly cause they were abit wider. Got one arm a tad longer, it helps but it's still there a little. Originally set them equal. Drive it and see what you think, adjust from there.

 

I have the exact same setup! I set mine as they suggested, and my vehicle drives perfect. If your unsure, start at 23" and see how it drives...Good luck!

 

I have mine equal lengths at 23 1/8 and no pull with 35" mt's.

 

Thanks all for the information, I will start at 23" both and later fine tune the lenght.

 

I installed the same TF lift yesterday. I went with 23" on both control arms and my Jeep drives great. It drives straight and true with no pulling either direction.
