These aren't your average round tube sliders. The inner rails and mounting legs are made from 2x2" heavy wall square tubing and finished with large 3/16" thick CNC-cut frame mounting plates and gussets that ensure these sliders will stand up to the harshest abuse you can throw at them. We laser cut the frame mounting brackets in-house, with each bracket custom tailored to the 4Runner's passenger and driver side frame profile at each mounting point. This allows us to mount these sliders to the truck using all factory holes in the 4Runner's frame. No frame drilling, welding or modification is required (Although 2 additional optional holes are pre-cut into the passenger side mounting plate for hard offroad use). Our frame mounting brackets wrap around the outer and bottom faces of the frame, and then we run bolts through the frame and into nuts that get secured on the backside. This means that in order for these rock sliders to fail, you would have to simultaneously snap the heads off the bolts and deform the 3/16" thick steel brackets enough to lift away from your frame! You can rest assured that these sliders will hold up to whatever trail hits you can throw at them.
This mounting design also ensures that those big trail impacts will get spread out over a large area of your truck's frame. The massive CNC cut gussets bridge the angle between the mounting legs and mounting plates (the highest stress areas in the entire slider) and create super stiff sliders that will not bend or flex excessively under the most extreme conditions! As a nice finishing touch, the ends of the square main rails are tapered at a 45 degree angle to ensure that they will not become battering rams if faced with a rock or stump.
These sliders come in pieces that are pre-bent and pre-cut. Simply line them up as per the provided assembly directions and diagrams, weld them together, and install them on your truck. To make it even easier, the kits ship with clear and detailed step by step directions that are accompanied by tons of diagrams and pictures. The 6 (3 per side) mounting legs ship over-length so the sliders can be positioned at your preferred angle and distance from the vehicle. Angle them up tight to the rocker panels for maximum ground clearance or set them level to provide a convenient step to access your roof rack. The pictured sliders are set at a 10 degree angle to provide a happy medium.
