Need a set of adjustable rear UCA's to set my rear pinion. After disconnecting my stockers and playing with pinion I figured I need about 1/4"-3/8" more than stock or about 17 3/4" max, This set my rear CV / RPezza at a nice happy position at the pinion but I will likely need spring wedges to correct bowing and keep track bar jam nut from hitting passenger side spring.

Which brand of arms can meet this length at minimum adjustment? I like RK but not sure they will work with my stock rear lowers?

 

I installed RK adjustable uppers a few weeks ago. I have a 3 inch lift and the RK arms barely had enough adjustment to set the pinion angle correctly. I actually had to shorten them as far as they will go to get it right. Anyhow, they did work and now my pinion angle is good.

 

Did you happene to measure them eye to eye at minimum adjustment?

 

Also, did you need spring correction or have track bar interference?

Does anyone know the minimum length of Rock Krawler rear adjustable upper control arms?
