Shims and Tcase drop also. Most lower control arms take no top arms in concideraton on 3" lifts but on a 4.5 I think 4.3's right about the arc of movement. I would run the same manufactures top arms so you don't end up with death wobble There is some adjustment on lower arms from the factory. You want 0 camber when it gets aligned. Your daughters must be either pissed or very happy. My daughter would be the first.
