TMR's custom traction-bar kits for leaf-sprung trucks help prevent spring wrap and driveline vibration by getting the power to the wheels. Pull trucks, street trucks, mud trucks, mega trucks, pulling trucks, all can benefit from track-bar and traction bar mounts. Spring wrap will eventually lead to costly driveline failure; reduce it with an anti-wrap or traction bar kit. Universal traction bar mounts and anti-wrap bar builder kits allow you to build a custom kit for your truck.
