my buddy has had 2 xjs none of them made it to 200,000 he did however fit 32s on 2 inches with some triming, also anthor buddys xj has 2inchs and sits on 30s which look about right for it, the other buddys xj sits on 33s on a 4 inch only wheeled with him twice but he did manage to flip it the 2nd time out and it roled once and came out pretty tweaked. My dads old 93 hixlux sat on its roof all night and all it needed was a new winsheild. that truck also had 260k and was not mantained at all that was 4 years ago b4 he changed jobs and i bet it is still running. and as far as putting a runner up against an xj my brothers out wheeled one with a 8 inch long arm 33s locked rear, with his 89 v6 33s locked rear and rear shackle as his only lift also my 85s got 280 and is still kicking it but this is just my
