Rocker panels seem to be made of some special rock-attracting supermagnets. We are not sure why 4x4 manufacturers use this material in making rocker panels, but we know how to counter it: with a Chuck Norrisesque defense, or as they are more commonly called, rock sliders. The Marlin Crawler rock sliders are made of 13⁄4x0.120-wall American-made tubing and now have four support bars and the company’s signature Crawler turtle laser-cut plate. They’re available in 58, 68, and 78 inches; we chose 68 for our 4Runner. A trio of jackstands helps mock up their mounting location.The Marlin Crawler rock sliders are made of 13⁄4x0.120-wall American-made tubing and now h Rock sliders come in all shapes and sizes. Some attach to the body, others to the frame. We’ve seen them tied into a rollcage with integrated sidesteps, others are rolled and clearance for, quite simply, added rock clearance. The goal is to keep rocks and other trail obstacles from gouging, banging, denting, and destroying your rocker panels and slowing your progress. We called up the guru of Toyota rockcrawling, Marlin Czajkowski, and his team of topnotch ’Yoto outfitters at Marlin Crawler and ordered up a set of the company’s new and improved rock sliders for our ’03 4Runner. These 68-inch rails required cutting and welding and painting, but they had our Runner boulder-ready in a long afternoon. The sliders attach to the frame via mounting tubes, but first frame scabs are added to the frame to help spread the load. We measured and mocked up the scabs before grinding clean the frame for a solid weld.The sliders attach to the frame via mounting tubes, but first frame scabs are added to the The support tubes are notched for the slider end, and we cut the frame end down to length with a chop saw. A ratchet strap holds the slider tight and locks the support tube in place for a “no gaps” weld. We primed and painted the sliders, but you could powdercoat them and then spray-paint just the final weld to the frame.The support tubes are notched for the slider end, and we cut the frame end down to length Small gussets are added to the top of the support tubes for strength.
