Add power to a 2011-2019 Chevrolet Silverado / GMC Sierra 2500HD/3500HD Duramax and the axle wants to twist — that is how u-joints, driveshafts and axle housings get destroyed. The Wehrli 60" Traction Bar Kit (Manufacturer Part # WCF100851) is a complete kit with mounts, built in house and carrying a lifetime warranty against bending or breaking to the original purchaser. Check your cab and bed configuration in the Notes before ordering.
Why Choose the Wehrli 60" Traction Bar Kit?
- Lifetime warranty against bending or breaking – to the original purchaser. Wehrli builds these in house and stands behind them permanently.
- RockJock Johnny Joints at the frame – rebuildable and greaseable, and they let you adjust torsion on the axle or correct for a raised or lowered rear.
- Poly bushings at the axle – deliberately not solid heims on both ends. Solid-on-solid is the setup people complain about for noise and vibration.
- Mounts included – axle brackets bolt to the bottom of the axle tube through the u-bolts; frame brackets weld on at the front.
- Grade 8 hardware throughout.
- Zinc primer under the color – more than ten times the corrosion resistance of a single powder coat, which matters on parts that live under the truck.
Kit Includes
- Two 60" heavy duty traction bars
- RockJock rebuildable and greaseable Johnny Joints (frame side)
- Heavy duty polyurethane bushings (axle side)
- Frame side weld-on mounts
- Axle side bolt-on mounts
- Grade 8 hardware
- Zinc primer base coat with custom powder coat finish
Installation Highlights
Axle brackets bolt to the bottom of the axle tube using the axle u-bolts. Frame brackets weld on at the front — welding is required for this kit.

Notes
- ⚠ Regular Cab Long Bed owners — measure first. Measure 60" forward from the bottom of the rear axle and check you have clear frame to land the front brackets. Some trucks have fuel tank brackets right there, and those need the 68" bars (WCF100853) instead.
- ⚠ Extended Cab Long Bed or Crew Cab Long Bed: use WCF100853, not this kit.
- ⚠ Lifted trucks. If your u-bolts face up instead of down, use WCF100855. If your rear lift block is taller than 5", use WCF100853.
- Lead time varies by color. WCFab Red, Gloss Black, Flat Black and Gloss White are stocked and ship in 3-5 business days. All other colors are made to order on a 10-15 business day lead time.
