TJ Rear Coil Correction Kit

The TJ Rear Coil Correction Kit fixes the bowed, leaning rear coil springs that plague lifted Jeep Wrangler TJ and LJ builds. When you lift a TJ, the factory coil seats no longer sit square under the spring, so the coil bows and can unseat on flex. These CNC-bent brackets re-index the lower seat for a straight, properly loaded spring — and give you the option to move to a 1 in. stretched location for a longer, more stable wheelbase.

Key Features

• CNC laser cut and CNC bent from 3/16 in. thick steel for a weld-in bracket that outlasts the factory stampings
• CAD-designed using models sourced directly from Chrysler for exact frame fitment
• Choose stock location or a 1 in. stretch position to push the axle rearward
• Factory trackbar mount location is etched into the plate as a cutout reference
• Etched alignment mark speeds up square, repeatable installation
• Accepts the factory jounce cup and bolt so your OEM bump stop hardware carries over

Fitment & Compatibility

Fits the Jeep Wrangler TJ (1997-2006) and the longer-wheelbase LJ Unlimited. This is a weld-on part for the rear frame coil seat area and is intended for coil-sprung TJ/LJ chassis. Pairs naturally with front frame work such as the TJ Front Frame Coil Buckets for OEM Bumpstops when you are refreshing rusted or abused factory coil mounts.

Frequently Asked Questions

Will this fit my Jeep?
Yes, if it is a coil-sprung Jeep Wrangler TJ (1997-2006) or LJ Unlimited. It is designed around Chrysler CAD data for the TJ/LJ rear frame.

Does the kit require welding?
Yes. The correction brackets are weld-on parts. Plan on a MIG welder, clean bare metal, and the etched alignment mark to index them square before you lay a bead.

What is the difference between stock and 1 in. stretch?
Stock location keeps the axle in the factory position with corrected spring seat angle. The 1 in. stretch position shifts the rear axle back roughly an inch for a slightly longer wheelbase and improved climbing stability.

Why do I need coil correction after a lift?
Lifting a TJ changes the angle of the spring seat, which makes the rear coils bow and can let them unseat during articulation. This kit re-indexes the lower seat so the spring stays straight and properly captured.

Can I keep my factory bump stops?
Yes. The bracket accepts the factory jounce cup and bolt, so your OEM bump stop hardware transfers over.
