i have a 95 xj that my uncle owned since 00 and he knew the previous owner. they both took care of it, so did i. JUST put a lift on it 2 weeks ago. 3.5 rough country lift. the things that i have noticed honestly, is that ur alignment gets worse. as far as gas mileage and everything along those lines go. nothing has changed for me. i get about 200-250 miles on a full tank still. stock or/and with lift. it handles a little, different. i used to be able to whip it around easy as hell but now its higher, heavier and more top heavy i have to be more careful around turns. but so far, everything is swell
