JL APEX Rear Axle Truss

The JL APEX Rear Axle Truss stiffens the M220 rear housing under your Jeep Wrangler JL so it holds up to larger tires and aggressive trail use. Its patent-pending peaked APEX top provides more rigidity than a flat-top truss, weighs under 10 lbs, and drops onto the axle pre-bent for a quick weld-on install.

Key Features

• Patent-pending APEX peaked-top profile for greater rigidity than a flat-top truss
• CNC laser-cut in-house from 3/16" mild steel, under 10 lbs
• CNC-bent long seams let you drop it on the axle and weld, no puzzle-piece assembly
• Modeled from Dana and Jeep 3D data for fit and clearance
• Roughly 70% less welding than older truss designs, reducing heat warp

Fitment & Compatibility

Fits the M220 rear axle found in Jeep Wrangler JL (2018-present) models: all Rubicons, plus Sport and Sahara trims with a manual transmission, and all automatic-transmission JLs equipped with a limited-slip differential. A version for the smaller M200 rear axle is not available at this time. Pair it with the JL/JT APEX Front Axle Truss up front, or move to a full one-ton setup with the JL 1-Ton UD80 APEX Rear Axle Swap Kit & Truss.

Frequently Asked Questions

Does this fit my JL's rear axle?
It fits the M220 rear axle. That includes all Rubicons, Sport and Sahara models with a manual transmission, and all automatics with a limited-slip differential. It does not fit the smaller M200 axle, and an M200 version is not offered at this time.

How do I know if I have an M220 or M200?
Rubicons use the M220. On Sport and Sahara trims, manual-transmission and limited-slip automatic models generally have the M220, while base open-diff automatics typically have the M200.

Does it require welding?
Yes. It is a weld-on truss for competent welders. MIG welding with moderate pre-heat and post-heat is recommended, alternating sides to limit warping.
