Nerf bars play an extremely important function in the overall durability of a Short Course racer by protecting the sides of the chassis and fragile body of the truck, A weak nerf bar can expose the body and chassis to severe impact damage from side impacts, roll over"s and T-bone crashes, just to name a few, RPM has once again stepped up to make the most durable and well-designed nerf bar for the Traxxas Slash and Slash 4 x 4, The RPM nerf bar eliminates the stock hook-over-the-chassis that supports the nerf bar and replaced it with a structural cross rib running parallel to the chassis for optimum rigidity and anti-deformation characteristics, By eliminating the hook, installation is easier; the nerf bar doesn"t have to be deformed to get it in position and the nerf bar no longer pulls on the side of the chassis when it takes a hit, Color: Blue, SKU: RCHOB1764
