Product details

The kit comes with a custom set of leaf spring shackles designed to clear the bumper in the range of movement. The rear bumper also features 3/4 inch thick d-ring recovery mounts that pass through the bumper and welded on both sides. The bumper welds to the back of the factory cross member and has two side frame plates to cover the sides. This kit does include new spring shackles as noted. The shackles are CNC laser cut from 1/4 inch high strength steel plate. The shackles measure 4 inches center to center and do have a 3rd cross bolt for additional support.

Bushings NOT included.

Your factory fuel tank will not fit and you will need either the Motobilt stretch underbody tank MB5016 or you will need a fuel cell in the back tub area of the Jeep. See MB5000-YJ

Notes

We typically use a stock XJ leaf spring in the back and factory YJ springs for the front.
If purchasing new rear springs simply match the height of the XJ springs to that of the front YJ springs. I.e. 2.5” springs in front, then 2.5” in rear. If you are attempting to use YJ springs instead of XJ Springs you will only gain 2”s of stretch and not the full 6”s.
We offer optional spring hangers (Part #: MB1531) if you prefer to reuse your YJ rear springs, if using XJ springs then these are NOT necessary.
Works in spring over or spring under applications.
You do not outboard the springs like you would on the front. You will cut your spring perches off if necessary on wider axles and weld new ones on in the correct position.

Additional product details & documents

The Motobilt Jeep Wrangler YJ Wheelbase Stretch Kit is a great way to move your rear axle back roughly 6 inches. The Motobilt Jeep Wrangler Wheelbase Stretch Kit is designed to use Jeep XJ rear leaf springs on the rear of your Jeep YJ (1987-1995). Installing this kit moves the rear axle back about 6 inches. The kit incorporates a custom rear bumper and shackle hangers in one part. The shackle hangers are positioned high on the bumper to keep the overall Jeep ride height lower for better center of gravity. The ends of the bumper are tapered in to allow better clearance for the shackles with the rear axle at full droop.

Bushings NOT included.
