The Go Rhino RB20 Slim Line running boards are cab-length steps for the 19-22 GMC Sierra 1500 Crew Cab (New Bdy), supplied as a kit with brackets and finished in a bedliner coating. Built from 16-gauge zinc-coated galvanized steel, they measure 5 1/2 inches across at the widest point, compared with 7 1/2 inches for the original RB20.

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.
