THE ONLY NERF BAR THAT DOES NOT APPLY FORCE TO THE WEAK FACTORY LOCATIONS! We found through racing that the mounts would bend and compromise your rear trailing arm mount. CA nerf bars use brackets that relocate the tubes to the frame. 100% high grade DOM steel. 100% TIG welded. These nerf bars have been developed through rigorous race testing. Designed for wheel to wheel racing like short course or to make sure you do not catch a tire on a tree or other obstruction while XC racing or trail riding.
