So plan on at least one set of adjustable control arms in the rear. I would consider the lowers, because you may be able to better set the axle position (a little back) to compensate for your lift, as well as the pinion angle.

FYI - We are still running the stock driveshaft in the rear of that JK.

Thanks for running the Dynatrac Ball Joints. We deeply appreciate your recommendation to others.
