There are no body mounts on an XJ Cherokee. So you can not do a body lift. Why not do a spacer lift and add a laef. Thay would only be about $150. About the same price as a BL.
if i'm not mistaken, cherokees are a unibody design, making a body lift impossible. There are so many good suspension lifts available for them though, save up and you wont regret it.
