ROCK SLIDERSFab Fours Rock Sliders are crafted from 3/16 in. steel, finished with full-length TIG weld down the flange to match constant radius. It boasts a signature knife-edge theme, vertical plate that matches the radius of the body for traditional protection, top surfaces that serves as entry step as well, and fully-welded boxed design for unparalleled strength. Tying-in to the body mounts and 15 places per side on the body gives maximum rocker panel protection.
