I have 3" lift knuckles up front, 2" spacers and z71 coils in the rear. I like it but starting to have the itch to do more....Only problem I have is I can not find a 6" lift for a 2wd. Will a 4wd lift work with a 2wd? Seems like it would, I just wouldn't use some of the kit like the differential drop parts and cv spacers. I already have 6" Stainless brake lines installed. Am I on the right track or way off in left field?
