Our rock sliders are created using 3D scanning technology that allows us to take advantage of the existing structural holes on the vehicle's frame, which in turn eliminates the need to drill into it. Using the scanned information, we CAD design the sliders and laser cut each component to maintain precision and the maximum amount of strength. We use thick plates in the areas that need it most and lighter material in less crucial areas to create a design that is less bulky but that does not jeopardize function. We take care to include details like the reinforced triangular support gussets that provide more rigidity between the mounting plate and each extension. Our sliders not only protect your truck, they can also be lifted at any point with a hi-lift jack, serve as a door ding deterrent, and an easy step into the bed. RRW sliders are 100% made in the USA.
