Hi all - I did some searching but didn’t quite see this answered. My situation is that I have an unknown lift on my used TJ. It’s about a 3.5-4” lift with a mixture of control arms. Front are adjustable busing style CORE Offroad control arms and track bar, their level 1. The back are stock control arms with stock track bar with a lift bracket.

There’s a local guy with a set of rock jock control arms. How much relative improvement and articulation should I expect from this change? I would probably do the track bar as well. I would bet I could get them for around $1300 so I’m trying to justify the purchase as all hahaha. I kind of need new rear upper CAs so that’s kind of a factor.

Thanks all

The RockJock arms are all adjustable length, which will allow you to correctly set the axle positions and the pinion angled. They will also use Johnny Joints which will offer more than enough misalignment and rotation to support the suspension travel.

The RJ track bars also fit very well. The rear ought to have RockJock angled axle bracket to compliment the double cardan rear drive shaft or should have with a 3-4" spring lift.
