The JK 1 TON APEX Rear 9 inch Truss Swap Kit is Artec Industries' next-generation, patent-pending truss and bracket package for swapping a Ford/Spidertrax 9-inch rear axle under the 2007-2018 Jeep Wrangler JK. The peaked-top APEX design is stiffer than a flat-top truss while weighing less and requiring far less welding, so your one-ton build goes together faster and comes out straighter.
Key Features
- Patent-pending APEX peaked-top truss delivers more rigidity than a traditional flat-top design
- CNC laser cut in-house from 1/4" and 3/16" mild steel — strong yet light at roughly 40 lbs total
- CNC bent in-house so the truss drops onto the axle and is ready to weld, with no puzzle-piece assembly
- Modeled from Spidertrax and Jeep 3D data for precise fit and clearance to surrounding components
- About 70% less welding than previous truss designs, which means less warping and faster turnaround
- Long seams are pre-bent, eliminating the time spent welding seams together
Fitment & Compatibility
Fits the Jeep Wrangler JK (2007-2018) being converted to a Spidertrax 9-inch rear housing. Designed to accept factory-style link, coil, shock, anti-sway bar, and trackbar mounting when built with the matching brackets. Welding and fabrication experience are required.

Frequently Asked Questions
Which axle and Jeep is this for?
It's built for a Spidertrax/Ford 9-inch rear axle going into a 2007-2018 Jeep Wrangler JK.
How much welding is involved?
The APEX truss requires about 70% less welding than older flat-top designs because the long seams are pre-bent. It still requires a competent welder and should be tacked in stages to control heat and warping.
Do I need the brackets too?
If you're starting from bare brackets, pair this with the JK 1 TON APEX Rear Axle Swap Brackets. Building the front to match? See the JK JL JT 1 TON APEX Front 9 inch Swap Kit.
Is there a budget alternative?
Yes — the JK 1 TON BASICS Rear Axle Swap Kit with Truss is the value-focused option.
