JK2TJ Rear Axle Swap Kit with Truss

The JK2TJ Rear Axle Swap Kit with Truss supplies all the brackets and trussing to swap a factory JK Dana 44 rear axle into a TJ or LJ Wrangler. It reinforces the entire housing while re-establishing the factory link, sway bar, and shock locations, so the stronger JK rear bolts into your suspension geometry instead of forcing you to build it from scratch.

Key Features

• 1/4" thick mild steel truss and brackets for far more strength than the factory or typical aftermarket brackets, precision CNC cut and bent.
• Includes every bracket for a complete rear swap: upper and lower control arm mounts, shock mounts, sway bar mounts, track bar mount, and coil spring mounts.
• Brackets jig into the truss and set their own position, eliminating the guessing and measuring that eats up install time.
• Track bar mount includes both a factory location and a lifted-bracket location for aftermarket lifts.
• Truss is reinforced with interlocked 1/4" gussets for maximum strength and easy assembly.
• Low-profile design keeps the axle stronger and sleeker so it clears vehicle components and tucks in cleanly.

Frequently Asked Questions

Which Jeeps does this rear kit fit?
It provides the brackets to swap a JK Dana 44 rear axle into the TJ Wrangler (1997-2006) and LJ Wrangler (2003-2006).

Does it include a track bar mount for a lifted Jeep?
Yes. The track bar mount has both a factory location and a lifted-bracket location, so you can correct axle centering after installing an aftermarket lift.

Do I need to weld it on?
Yes. The truss and brackets are weld-on. They jig into the truss to self-locate, but final installation requires welding to the axle housing.

Does it include the upper control arm mounts?
Yes. Unlike the front kit, the rear kit includes both upper and lower control arm mounts along with the shock, sway bar, track bar, and coil mounts.
