Wehrli 11-19 Chevy & GMC Duramax RCLB/CCSB/ECSB Traction Bar Kit- Flat Black

When you're adding more power to your Duramax truck, especially a 2011-2019 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD, you're going to want to consider a traction bar kit like this one from Wehrli Custom Fabrication. This kit includes the two 60-inch heavy-duty traction bars, frame-side weld-on mounts, axle-side bolt-on mounts that attach using your existing u-bolts, and all the necessary Grade 8 hardware to put it all together. It's designed to stop your axle from twisting under the increased torque, which can save you from broken driveshafts, universal joints, or even a twisted axle housing.

Wehrli uses a smart combination of connection points to keep things working smoothly and comfortably. At the frame end, you get a rebuildable and greaseable RockJock Johnny Joint. This allows for adjustments if you change your truck's ride height or need to fine-tune the axle's position. For the axle connection, they've opted for a heavy-duty polyurethane bushing. This is a practical choice because it helps reduce the noise and vibration you might otherwise feel if both ends used solid heim joints, a common complaint with other setups. The bars themselves are finished with a durable flat black powder coat, applied over an epoxy primer base coat for over ten times the corrosion resistance compared to a standard single coat.

This kit is built to last, backed by a lifetime warranty against bending or breaking for the original purchaser. It's designed to fit Regular Cab Long Bed, Extended Cab Short Bed, and Crew Cab Short Bed models of the 2011-2019 Silverado and Sierra HD trucks. While the frame mounts require welding, the axle mounts bolt directly on, making installation straightforward for someone comfortable with fabrication work.
