Description
Description
Put your power to the ground on your 2020-2025 Chevrolet Silverado 2500/3500 HD or GMC Sierra 2500/3500 HD with the WCFab Traction Bar Kit — built in-house at WCFab and backed by a LIFETIME WARRANTY against bending or breaking (to original purchaser). Traction bars are a necessary upgrade when adding horsepower or towing heavy, preventing axle twist that can lead to broken u-joints, pinion yokes, driveshafts, and even twisted axle housings.
Why Choose the WCFab Traction Bar Kit?
- Lifetime Warranty – Backed against bending or breaking to the original purchaser.
- Stops Axle Twist – Prevents the axle wrap that destroys u-joints, pinion yokes, driveshafts, and axle housings.
- RockJock Johnny Joints – Rebuildable, greaseable heim connection at the frame allows adjustment of axle torsion and ride-height changes.
- Poly Bushing at the Axle – Heavy-duty polyurethane bushing decreases noise and vibration common with solid heims on both ends.
- Grade 8 Hardware – Connects the bars to the frame and axle mounts.
- Superior Corrosion Resistance – In-house powder coat over an epoxy primer base coat increases corrosion resistance by more than ten times versus a standard single-coat application.
- Color Choice – Finished with WCFab's professional in-house powder coat in your color choice.
- Made in USA – Built in-house at WCFab.
Kit Includes
- 60" heavy-duty traction bars
- RockJock Johnny Joints (frame side)
- Heavy-duty polyurethane bushings (axle side)
- Axle-side bolt-on mounts
- Frame-side bolt-on (CCSB only) or weld-on mounts
- Grade 8 hardware
