Wehrli 20-24 Chevy & GMC Duramax RCLB/CCSB/ECSB 60in. Traction Bar Kit - Illus Purple

If you're looking to put more power down with your 2020-2025 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD, especially when towing heavy loads, axle wrap can become a real issue. This Wehrli traction bar kit is designed to keep your rear axle planted, preventing it from twisting under load. Axle twist can lead to a cascade of problems, including broken U-joints, pinion yokes, driveshafts, and even damage to the axle housing itself. This kit addresses that directly by providing a strong, stable connection between your frame and axle.

Wehrli builds these bars in-house using 60-inch heavy-duty bars and connects them to the frame with a weld-on mount (though Crew Cab Short Bed models can use a bolt-on option). At the frame connection point, you'll find a rebuildable and greaseable RockJock Johnny Joint, which allows for adjustment if you change your rear suspension height. For the axle connection, they use a durable polyurethane bushing. This choice helps reduce the noise and vibration that can sometimes come with solid heim joints on both ends, making for a more comfortable ride. The kit includes Grade 8 hardware for all connections, and the bars are finished with a custom Illusion Purple powder coat over an epoxy primer base coat, which Wehrli states increases corrosion resistance significantly. This kit is backed by a lifetime warranty against bending or breaking to the original purchaser.

While the Crew Cab Short Bed models offer a 100% bolt-on installation, other cab and bed configurations will require frame modification and welding for the front mounts. For competition applications, welding the front mounts is recommended for maximum strength. This kit is a robust solution for diesel truck owners looking to improve their truck's performance and durability under stress.
