UCF Jeep YJ Back-Half Kit

YJ rear frame rails that keep factory width.

This YJ back-half kit replaces the frame from the up-sweep ahead of the rear tire back to the bumper, giving you a flat plane for a longer rear wheelbase stretch. Converting to coil-overs or ORI struts? See our TJ back-half kit.

Construction and specs

• Pair of 3/16" steel frame rails, the same width as the factory frame (they don't narrow)
• Pair of 1/8" thick body-mount crossmembers
• 1/4" thick steel bumper
• Four 3/16" steel reinforcing plates that weld on either side of the back-half frame rails and the factory frame rails

What's included: two frame rails, two body-mount crossmembers, the rear bumper and four reinforcing plates.

Install notes

• This kit requires a 1" body lift.
• Ships unassembled and must be welded up by the installer before installation.

Finish: ships raw, with no paint or powder coat, so you can finish it however you like.

Fitment: confirmed vehicles

• Jeep: Wrangler YJ 1987–1995
