Hey guys, I am putting my new PR44 on my Jeep in the next couple weeks and I always hear people say that the Unlimited model is built with extra caster for lifted vehicles. Does anyone know the exact specs for this?

I currently have Evo 3 inch coils on my 2 door and Rock Krawler lower adjustable arms. Anyone know what length they need to be for everything to be in spec and if I will NEED upper adjustables?

 

10° i believe
I would shoot for 5/5 split

Remove lowers, place jack under pinion. Use a angle on the pinion output (+5°)
Take one RK arm, bolt up frame end and spin the axle side joint so the bolt slides in.
Snug down jam nut. Remove arm, pair together and slide to bolts through to match the lengths.
Tighten jam nuts (275-325), install and bolt torque (125), done.

 

Yup... 10 degrees of separation.

Thanks guys.

 

If it is caster corrected and you are running close to what size lift it is caster corrected for then you should be same length as factory arms.

 

The caster that is built into the ProRock 44 unlimited housings is 10 degrees of separation between the pinion and caster axis. The axle can be adjusted using the control arms between 6-8 degrees caster and 2-4 degrees at the pinion. Adjustable upper control arms will help with aligning the axle, but consult with the shop that is performing the install to see what they recommend for your exact set up.
