Add power or tow heavy with a 2020-2025 Chevrolet Silverado / GMC Sierra 2500HD/3500HD Duramax and the axle wants to rotate under load — wheel hop, inconsistent traction, and eventually broken u-joints, pinion yokes, driveshafts or a twisted axle housing. The Wehrli 68" Traction Bar Kit (Manufacturer Part # WCF100876) is a complete kit with mounts, built in house and carrying a lifetime warranty against bending or breaking to the original purchaser. Check your configuration in the Notes before ordering.
Why Choose the Wehrli 68" Traction Bar Kit?
- Lifetime warranty against bending or breaking – to the original purchaser. Built in house at WCFab.
- Stops axle wrap without binding the suspension – the axle is stabilized under load while normal articulation is retained.
- RockJock Johnny Joints at the frame – rebuildable and greaseable, and they let you adjust axle torsion or correct for a raised or lowered rear.
- Poly bushings at the axle – deliberately not solid heims on both ends, which is the usual cause of noise and vibration complaints.
- Mounts included – axle brackets bolt on, frame brackets weld on.
- Grade 8 hardware throughout, with a zinc primer base coat under the powder for corrosion resistance.
Kit Includes
- Two 68" heavy duty traction bars
- RockJock rebuildable and greaseable Johnny Joints (frame side)
- Heavy duty polyurethane bushings (axle side)
- Axle side bolt-on mounts and frame side weld-on mounts
- Grade 8 hardware
- Primer base coat with custom powder coat finish
Installation Highlights
Axle brackets bolt to the axle. Frame brackets weld on — welding is required for this kit.
