Why do they call them nerf bars? What are Nerf Bars? The nerf bar has its origins in the world of racing. Nerf is the term for when a racer bumps another car in order to pass them during a race. In order to do this move safely, race cars are equipped with tubular fixtures on either side of the car body. Pit Stop USA has a great selection of nerf bars for Sprint Cars and other open wheel racing applications.
