Triangulated GM 14-Bolt 1-Ton Swap Kit with Truss for Jeep Wrangler TJ 1997-2006
This kit hangs a GM 14-bolt one-ton rear axle under a 1997-2006 Jeep Wrangler TJ on a triangulated four-link. When 37s and repeated hard hits have moved past what any half-ton axle tolerates, the 14-bolt is the standard answer, and this bracket set locates it with triangulated upper links instead of a track bar — removing the bind and failure points of the factory layout. Thick 3/8" trussing across the top ties the housing together so the whole assembly takes abuse as a unit. It is aimed at TJ builders committed to a true one-ton rear, not a mild upgrade.
Features
- 3/8" thick truss top with 1/4" gussets and 1/4" brackets, precision CNC cut and bent
- Complete bracket set: upper and lower control arm mounts, shock mounts, and coil spring mounts
- Triangulated upper control arms delete the track bar for stronger, cleaner rear geometry
- Outer brackets self-locate to the truss — no measuring during fit-up
- 2.63" upper link mount width accepts a 1.25" rod end kit or other large joints
- High Clearance option flattens the lower link brackets and shock mounts against rock strikes
- Made in the USA
Two cautions before ordering: OEM control arms cannot be used — the triangulated design needs new upper links and frame-side brackets — and the 14-bolt's large third member will not clear a factory TJ sway bar, so budget for an aftermarket rear bar since factory-style sway bar mounts are not included. Install is weld-on and needs real fabrication skill. Running a Ford donor instead? See the Triangulated TJ Sterling 1-Ton Swap Kit. Match the rear with a TJ 1-Ton Front 60 Swap Kit up front, and browse all our complete axle sets.
Triangulated GM 14-Bolt 1-Ton Swap Kit with Truss for Jeep Wrangler TJ 1997-2006 FAQs
What axle does this kit fit, and can I keep my factory sway bar?
It is built to swap a GM 14-bolt one-ton rear axle into a 1997-2006 Jeep Wrangler TJ. The 14-bolt's large third member will not clear a factory TJ sway bar, so the kit omits factory-style sway bar mounts — plan on an aftermarket rear sway bar.
What suspension parts do I need beyond the kit?
New upper links and frame-side brackets, since the triangulated four-link deletes the track bar and is not compatible with OEM control arms. The truss's 2.63" upper link mounts are sized for a 1.25" rod end kit or other large joints, so choose link hardware accordingly.
How involved is the installation?
This is a weld-on kit that requires welding and fabrication skill — the truss and every bracket weld to the 14-bolt housing. The outer brackets self-locate to the truss, so positions are set without measuring, which keeps the job to fit-up, welding, and link setup rather than full custom fabrication.
