I've bought and installed the kit 5/7 on my 15 rcsb and really I like the kit. But I'm having issues. Flip kit was easy, driver front went together perfectly, but from jump the pass side was off. Im not sure what the deal is but we are working on it. truck has 23k and never in a fender bender. The plastic knockouts were still in the alignment cams. Aluminium control arms and spindles. Cams are maxed and can't get the pass side to align. Driver was perfect. but both tierods needed trimming to get the toe set.
