The RB10 Slim Line running boards offer the same heavy duty toughness as the original RB series, but with a slimmer design that fits tighter along the cab for increased ground clearance when off-roading. Constructed from 16-gauge zinc-coated galvanized steel, the Raptor-inspired boards were built to protect your panels from dying debris while providing a full-length step platform. The classic louvered design is four inches across at its widest point (compared with six inches of the original RB10) and are offered in cab-length sizes that fit most popular trucks, Jeeps and SUVs. The RB10 slimline is available with a protective bedliner coating that carries a 5-year limited warranty.
