Go Rhino RB20 Slim Line Running Boards, 57in, Boards Only, Textured Black, Bronco 2dr 2021+

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).

RB20 Slim Running Boards come with a Limited Lifetime warranty on materials and construction and a 5-Year Warranty on the Textured Black Finish.
