I just installed the Pro Comp 4" lift on my 95YJ a couple of months ago. I am running 33x12.50 tires and have decent clearance. I have read a lot of bad things about Pro Comp, but I love mine. It rides better than stock on my Jeep. It's also warrantied for as long as it is installed on the vehicle so if they sag they can be replaced.
95, 4" susp. lift, 33x12.50 ProComp M/T's, custom square tube bumpers, , energy bushings, 4.0 HO, everything stock, 1" or 2" body lift and who knows what else coming soon.
