Why would I want a Motobilt back half kit? If you are planning on performing a custom link suspension in the back of your Jeep, then a back half kit will give you the extra clearance needed for all of the components to fit. When fabricating or installing a link suspension in the back of your Jeep, you are most likely going to be stretching the wheel base and moving the axle back. When doing this you will soon find out that your stock frame is in the way. You can see in the following picture how the frame rises up from the skid plate but then towards the end drops back down. This is what causes the most trouble when trying to fit a custom suspension and stretch the wheelbase.
Also, there is not a lot of room between the stock frame rails and the inside of your tires. Building custom four link suspension on a Jeep YJ, TJ, or LJ does not have to be difficult. The Motobilt Jeep back half kits are an effective way to gain clearance for suspension components like coil overs shocks, bypass shocks, or ORI struts. The Jeep Back Half Kit moves the frame rails to the bottom side of the tube. The frame rails will mount directly to the bottom side of the rear floor board for a tight compact fit. It should be noted the kit requires cutting sheet metal on the body just below the tailgate to allow the frame rails to extend out. The bumper is then attached in this new location. The Motobilt kit comes complete with a rear bumper.
What else do I need to do when installing a Motobilt Back half kit? The installation requires that the body remain on the frame of the Jeep. We have body mount tabs located on the long straight sections of the frame that will mount to the factory cross member mounts of the Jeep tub. These will be used as a reference point on where to cut your frame.
