If you are in the market for a new set of steps, but you aren't looking for anything too bulky, then the RB20 Slim Running Boards will be just what you need! These boards feature the same raptor styling as the original RB20 Running Boards, but they are much slimmer at 5.5 inch the widest point vs 7.5 inch wide, like the full size boards. They are made from 16-gauge galvanized steel and come in your choice of textured black powder-coat or premium protective bedliner coating, both of which provide excellent protection against the elements!
