The Artec Industries Rear TJ Coil Perches and Retainers are the finishing piece for a rear axle swap in a coil-sprung Jeep Wrangler TJ. When used with an Artec modular truss, they locate the rear coil springs in the factory position, turning a fabrication headache into a measure-free bolt-and-weld job. Sold as a pair for both sides of the axle.
Key Features
- Precisely locate the rear coil springs in the factory TJ position when paired with an Artec modular truss, so no measuring or trial-fitting is needed
- Clockable to any angle to dial in spring seating for larger lifts
- CNC laser cut and bent from 1/4" steel
- Complete kit: bottom perches, tubing spacers, flat tube caps, spring retainers, and 1/2" retainer hardware for both sides
- Spring retainers keep the coils captured through full droop on the trail

Frequently Asked Questions
Which Jeep does this fit?
It is made for the coil-sprung Jeep Wrangler TJ (1997-2006) rear axle during a swap. It relocates the coil seats to the factory position so the spring rate and ride height stay predictable.
Do I have to use it with an Artec truss?
Yes, it is designed to work with Artec modular rear trusses; the perch geometry references the truss to place the springs in the stock location without measuring.
Which tube-diameter variant should I choose?
Match the variant to your axle housing tube: order the 3.0" version for a 3.0" tube and the 3.5" version for a 3.5" tube. Measure the outer diameter of the bare tube to confirm.
Is welding required?
Yes. The perches and retainers are welded to the axle tube. They are clockable before welding, so you can set the spring angle for your lift height first.
