So I'm installing my Currie rear upper control arms and I have a couple of questions. How long do they need to be for a 4 inch lift? How do I know if my axle is centered? (Adjustable rear track bar) Is it safe to say that the axle is square to the frame as long as the arms are the same length? Thanks!

Since not all 4" lifts are exactly 4" lifts and all Jeeps are not exact, there's no way of answering your first question. The best way to do it is to adjust your pinion angle and go from there. You can check to see if your axle is centered by using a plumb bob on level ground. The arms may need to be different lengths too so that doesn't help much either does it?:)
