Frame-Mounted | Heavy-Duty Bolts | Tri-Guard Powder Coat Bolt-On Strength. Welded-Level Rigidity. Engineered for Real Trails. Our Jeep JK Rock Sliders combine the convenience of a bolt-on system with the unyielding strength usually found only in weld-ondesigns. Using a proprietary dual-fastener method—factory bolts plus Grade 10.9 bolts threaded through the frame rails—these sliders deliver true frame-level rigidity without any welding. Most sliders that bolt only to body mounts leave users vulnerable. They flex under heavy trail use and can damage the rocker panels. Our system anchors directly into the frame at multiple points, transferring loads into the vehicle’s strongest structure and resisting pull-out under extreme pressure (Grade 10.9 bolts into ¼″ steel can hold well over 10,000 lb before shear or pull-through).
