body lifts are cheap and quick. they do not offer any better off road capability, they only offer more body clearance for bigger tires. i also don't like the way they look. you will have a gap between your body and frame, because the body is being spaced off the frame. 1" is generally ok, anything more starts to look obvious and raises the center of gravity.
its all personal, if you don't mind the look then its fine. but like i said, they only offer more room for tires, no more suspension flex or travel. try to see some jeeps in person that have them to get an idea of how it looks. i've known guys that did 2 and 3 inch body lifts, and regretted it later. lots of people also end up taking them off for a 1 or no body lift. also after 1 " you start running into t case shifter changes, and gas filler neck and stuff like that. can you tell i don't like body lifts???
imo a much better first mod, or cheaper lift is a budget boost, spacer on the springs.
