IMO, a body lift does nothing exept make your rig appear taller and raise the center of gravity, if you are serious about wheeling, you need the essentials, larger tires to aid in climbing obstacles and clearance under the axles, suspension travel to help keep all 4 on the ground to aid in traction and stability, undercarriage clearance to aid in apex clearance especially if your running a rig with a longer wheel base ie: unlimited wrangler, as well doing all this while keeping your jeep at stock hieght vs width ratio ie: go up 4" go out 4" thus also helping clear the tires required for the previous essentials. With fender flares and an easy 4" suspension lift this jeep will fit 37's easy at full flex, so why would you want to make your rig even higher.
But I'm also 15 and still waiting on my power wheels jeep lift kit, Dam things are hard to find.
