I bought my xj with a lift already on it, not sure what brand but it's lift coils up front and blocks in the rear. Wasn't sure on the lift height so I did the hub to flare measurement, measured out to 3.75 in the front and 3.25 in the rear. I'm assuming that it's a 4 inch lift that has sagged a little, stock leafs are completely flat. Looking to get rid of the blocks and put new leafs on the rear to get exactly 4" of lift after it settles. I also have a heavy steel rear bumper with tire carrier so I may have to take that into account. Anybody have any recommendations? I may end up just doing the bastard pack to build what I need but I would rather buy new leafs and swap them out
