If you’re looking for running boards that can handle the rough and tumble of off-roading while keeping your truck or SUV looking sharp, the RB20 Slim Line Running Boards are worth a look. These boards pack the same heavy-duty punch as the original RB Series but come in a sleeker design that hugs the cab more closely. This means you get extra ground clearance, which is a game-changer when you’re navigating rocky trails or muddy paths.
Made from 16-gauge zinc-coated galvanized steel, these boards are built to take a beating. The Raptor-inspired design not only looks tough but also protects your vehicle’s panels from flying debris. Plus, the full-length step platform makes getting in and out of your ride a breeze, even when you’re loaded up with gear. The boards are 5 1/2 inches wide at their widest point, which is a nice trim-down from the original 7 1/2 inches, allowing for a cleaner profile.
You can choose between a protective bedliner coating or a textured black powder coat finish, both of which come with a solid 5-year limited warranty. And don’t worry about complicated installations—these boards come with all the necessary mounting brackets, and best of all, no drilling is required. They fit a variety of popular trucks, Jeeps, and SUVs, including the Toyota 4Runner from 2014 to 2021.
