Secure your suspension and eliminate performance-robbing axle wrap with the Wehrli Custom Fabrication (WCFab) Traction Bar Install Kit. Engineered for high-output diesel applications, these brackets provide the robust mounting points required to stabilize the rear housing during heavy acceleration or towing. The kit utilizes axle-side brackets that bolt directly to the bottom of the axle tube via the factory u-bolts, paired with front frame-side mounts designed for a permanent, weld-on installation.

Each component is built in-house at WCFab and finished with a zinc primer base coat and durable powder coating for maximum corrosion resistance. This kit includes all necessary Grade 8 hardware to connect the traction bars to the mounts.

Important Note: This part number (WCF100840) includes mounting hardware and brackets only. To complete the system, this must be combined with traction bar base part number WCF100837 or WCF100839, depending on your vehicle application.
