DC-Pro Nerf Bars were designed based on the collective input from riders and racers all around the world. The DC-Pro Nerf Bars features include a wider foot peg stance with inner crisscross teeth to reduce boot wear. A full 50" mounted width on the MX version. Feature the option of universal removable heel guards or quad-specific heel guards (sold separately). Both the foot pegs and heel guards (sold separately) were designed to help drain out mud and water to avoid clumping. The side profile features an aggressive rake to help prevent tangling with other quads in racing applications. All wear items are completely replaceable and the overall pro peg is universal to fit most sport quads just using different hardware packages; so, if you change quads, you do not need to buy a complete new set of nerf bars. The nerf bars are constructed of high-quality 6061 aluminum tubing for superior strength and durability.
