If you are going to take your TJ off road, I highly recommend that you keep your body lift to 1.25" or less. The reason for this is that when you are off roading the frame will naturally flex and twist. The further the body is from the frame then the more stress you will put on the body mounts/retaining bolts causing them to eventually loosen, stretch, and even fail.
Oh, and body lifts can be installed fairly easily by yourself in about two hours using a high lift jack and a basic socket set.

Ive never understood the need for a body lift... what are you accomplishing by getting one?
They arent nearly as common in JKs (which it appears you have). However, on TJs they are very popular in the 1-1.25" range.
This minimal body lift allows you to tuck your transfer case up closer to the frame rails (also called a Tummy Tuck) which results in higher clearance at the belly so you don't get hung up as easily. Many aftermarket gas tank skids prefer a body lift as well because the skid designs tuck the tank up higher...also for more clearance. On top of these two reasons, it also provides a little bit more tire clearance.

I agree with most everyone else. A 3" body lift is a bad idea. I would say 1 1/4" is the most you would ever want to do. I just installed a 1" Rokman body lift on my TJ for a tummy tuck and was very happy with the quality. The 1" was more than enough to stuff the 241 transfer case up with the new Rokman skid. It only took about an hour to do the body lift. It's pretty easy and all you need is some basic hand tools, a jack and a wood block for lifting the body. Rokman is a local business in Highlands Ranch and Jeff and Dave are very helpful.
