Just installed my 3.25 lift and after getting the front and rear on, the rear sits about 1.5" higher. I do have an aftermarket tube bumper up front, but I guess I just need to give it some time to settle?
Ok only reason I asked is because I did a 2" lift had the same issue because I failed to loosen the control arms before lifting and they got bound causing additional lift. One trip of hard wheeling got them settled in nicely and now sits more level
When I had my RC 3.25 lift I had the same problem. Get yourself the RC 4" front coils and your rear should be .5 higher. You always want the rear a little higher in case you have alot of passenger in your jeep or heavy stuff in the back.
