I thought you said, a while back, that you were gonna buy Eric Zappe's book? If you had, you would know that Cherokee XJ's have uni-bodies. They don't have a standard "Frame", like most vehicles, but have what is called Frame Rails that are attached to the body. So the answer is NO, you can't do a body lift. For less than $20 you can save yourself a lot of time, and $$. e.g., the tires you just bought, this book has info about tire fitment and rim requirements. Now you don't have to buy this book, or listen to me (of which you've done neither) and go about buying parts, working on, and modifying your Jeep by Trial and Error. There's nothing wrong with that method, many people have done that and have built some really nice rigs, although it took them a lot longer and cost 'em a lot more money than others who chose to research and plan first.
The path we choose to travel, albeit the same destination, is, of course, a personal decision.
