CMS CrMo Racing Kart NERF Bars


Competition Motorsport is proud to introduce our Chrome-Moly racing kart NERF bars, the ultimate high-performance side-impact protection for racing karts. Made in America, fully TIG welded from domestic 4130 CrMo steel, 0.75" diameter and 0.095" wall. Far stronger than typical electric resistance welded (ERW) NERF bars, the CMS bars are the ultimate in side-impact protection for your kart racer. We also offer customization (kart number upgrade shown), so your CMS NERF bars can stand out in a crowded field at any track!

We stock sizes to fit most popular kart chassis; if we don't have yours in-stock, we'll make them to your dimensions. In addition, we powder-coat each bumper in-house in your choice of over 6,000 ultra-durable, eye-catching colors (from the flattest black to shimmering metallics to candied chromes)! That way we can keep a close eye on quality and keep turn-around time to a minimum (a few days to a week).

There's no safer place for the racers in your family than in behind CMS racing kart NERF bars. Call us today at 844-438-7244, we'll help you choose a powder color and get your CMS bars on their way!
