Wherli Fabrication’s heavy-duty traction bars were designed to prevent the common issues associated with increasing the performance of your GM Duramax. These traction bars provide a significant increase in overall strength and durability to keep your rear axle safely secured where it belongs, eliminating the twisting movement (axle wrap) that typically leads to broken u-joints and driveshafts.
These high-quality traction bars feature Currie Enterprise rebuild-able and grease-able “Johnny Joint” style heim connections at the frame allowing full adjustment of the pre-load and overall length making them suitable for lifted and lowered applications.
The WCFAB bars offer a clean and simple installation with bolt on brackets for the rear axle along with a set of weld-on mounts for the frame for superior strength & durability. These bars come standard with a ZINC primer base coat along with your choice of powdercoat to ensure a long lasting finish to keep them looking fresh regardless of what you intend to put them through.
Important Notes:
Applications with upward facing U-bolts do not allow for a bolt on installation, these brackets must be welded to the axle tube.
Wehrli has designed this kit to work with several different applications, please verify your vehicles current setup and select the appropriate option above.
