# Go Rhino 15-19 GMC Sierra 2500/3500HD CC 4DR RB20 Slim Running Boards Kit (w/Brackets) - Bedliner Ct

The RB20 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 flying debris while providing a full-length step platform. The modern, bullet-stamped design is 5 1/2 inches across at its widest point (compared with 7 1/2 inches of the original RB20) and are offered in cab-length sizes that fit most popular trucks, Jeeps and SUVs. The RB20 Slim Line come with a Limited Lifetime warranty on materials and construction and a 5 year warranty on the Textured Black Finish.
