I ran 2.5" with 37's and now 3.5".
The jeep now is almost excessively high.
to be honest it came that way. ive really only done maintenance and new tires. it came with stock rubicon shocks on the rear when i bought it. the stealership replaced the leaking procomps and killed the ride. it had no drop/flex in the rear at all. when i replaced the rear shocks with the matching procomp shocks the ride improved (but its still pretty rough) . i rebuilt the front drive shaft cv joint and found a wear mark on the skid plate from the drive shaft contacting it. i would like to upgrade to a better lift ( tereflex or RK) down the road . my jeep weighs 4820 with no spare and me in it. 3:73 and 35's are "ok" but id like 5:13's to deal with the tires and weight. i think im right at the limit for gear vs tire size . i dont know how guys run anything taller go with out re-gearing.
Donut, looking at your pictures, that does not look like a typical 4 inch lift to me. i would have guessed 2.5, but maybe the pictures are deceiving...
the stealership told me this was the lift that was installed by the original owner when it was bought from them in 08. its just springs and shocks . ive had some small alignment issues , the front track bar mount has broken twice . but over all it been alright ish. it doesnt really flex for shit http://www.4wheelparts.com/Suspensio...t_pn=EXPK3089B
