So running 33's on 3.5" lift is not a problem? (with some triming of course) Wont this limit the travel of the suspension off road? It seems that the bigger the tire the less flex you have before your wheel is stuffed in your wheel well.
Lift height does not give you any more clearance at full stuff anyway. You will either have to cut, no matter what the lift, or lower the bumpstops. You can then gain the lost up travel by turning it into the extra down travel by simply raising the lower shock mounts, like I show on my site www.go.jeep-xj.info ) or lower the upper shock mounts the same amount you have changed the bumpstop height.
