Wehrli 01-11 Chevy & GM Duramax 60in Traction Bar Kit RCLB/CCSB/ECSB, Flat Black

Wehrli Custom Fab is known for building tough parts for diesel trucks, and this 60-inch traction bar kit is no exception. If you've boosted the horsepower on your 2001-2010 Chevy or GMC Duramax truck, you know that the rear axle can start to twist under load. This twisting can lead to serious issues like broken U-joints, driveshafts, or even a twisted axle housing. This kit is designed to bolt directly onto the bottom of your axle tubes and weld to the frame, keeping that axle planted and preventing unwanted rotation.

What sets this kit apart is the thoughtful combination of connection points. Up at the frame, you'll find a RockJock Johnny Joint, which is rebuildable and greaseable. This joint allows for adjustment if you change your truck's ride height or need to fine-tune the axle's torsion. Down at the axle, a heavy-duty polyurethane bushing is used. This choice helps cut down on the noise and vibration that can sometimes come with using solid heim joints at both ends, making for a more comfortable ride. The bars themselves are 60 inches long and connect to the frame and axle mounts using strong Grade 8 hardware. The entire kit is finished with a durable flat black powder coat, featuring an epoxy primer base coat that Wehrli says increases corrosion resistance significantly compared to a single coat.

This kit is designed as a 100% bolt-on installation for Regular Cab Long Bed, Extended Cab Short Bed, and Crew Cab Short Bed models, though welding the front mounts is recommended for competition applications. Wehrli backs this kit with a lifetime warranty against bending or breaking for the original purchaser, giving you peace of mind when you're pushing your Duramax to its limits.
