Do XJs normally look a little taller in back? I measured 20" from fender flare to te center of the axle hub on the back, and 20.5" in front, which is what a 3" lift is supposed to be, right? It still looks a little high in back. Maybe that's just because the old springs sagged a little? I'm thinking about adding a winch to the front, and I realllly don't want to add yet another spacer to even this thing out.
