Setup for Upper and Lower Adjustable Control Arms

I have D30/C8.25 Axle Assemblies, 5"s of Lift on my '96 XJ. What recommendations for center to center length for Upper Adjustable Control Arms and Lower Adjustable Control Arms should I set each pair at?

At present I have my Lower Adjustable Controls Arms set at 16.5"s for 5"s of Lift. I have Stock Upper Control Arms. I am sure that my Camber is way off because of this. I have bought a new set of Upper Adjustable Control Arms for my '96 XJ to replace the Stock Uppers.

Please, I need advice as to what to set the Uppers and Lowers to for 5"s of Lift.

I appreciate your help.
Thank you.

Here is a chart to help you figure what length your arms need to be at certain heights. Control arms lengths are important for castor and location of axle in the wheel wells. At 3", you will be ok with stock arms, just expect the axle to move back toward the cab a little and some minor bumpsteer.

FYI, control arms control caster angles, not camber.

the chart is a ball park figure and might be good enough, but you need to set up control arm length to get the best caster and pinion angles.

at 5" of lift on short arms, you might want to concider control arm drop brackets.
