JK D44 MODULAR Rear Truss

Artec's Modular Rear Axle Truss reinforces the Jeep Wrangler JK Dana 44 rear axle and gives you a flat, purpose-built surface to mount triangulated upper links. Built from 1/4" mild steel, the modular design spans the full housing to tie the tubes together and set up ideal link geometry, making it the backbone of a stronger JK rear suspension.

Key Features

• 1/4" thick mild steel truss, precision CNC cut and bent for tight fitment
• Low-profile modular design that mounts link joints with ideal geometry, roughly 8" from the axle centerline
• Spans the entire length of the axle, with optional perches, to reinforce the tubes rather than just the link area
• Interlocked 1/4" gussets for maximum strength and easy assembly
• Low-profile shape keeps the axle sleeker and less likely to interfere with vehicle components

Frequently Asked Questions

Which axle does it fit?
The Dana 44 rear axle in the Jeep Wrangler JK (2007-2018), as found on Rubicon models.

Why is it called modular?
The truss is designed to span the axle with optional perches and a flat top surface, so you can configure it around your link setup.

Where do the upper links mount?
The low-profile top places the link joints with ideal geometry, roughly 8" from the axle centerline.

Is welding required?
Yes. It is a weld-on truss and should be installed by a competent welder.

Compare it with the JK APEX Rear Axle Truss, and add Truss Upper Link Mounts or a JK Rear 3-Link Bracket to finish the linkage.
