CMS 4130 CrMo Rear Karting Bumper

CMS CrMo Racing Kart Rear Bumper


Competition Motorsport is proud to introduce our Chrome-Moly rear racing kart bumper, the ultimate high-performance rear 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) bumpers, the CMS bumper is the ultimate in safety for the rear end of your kart. And the design stands 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 it 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 front of a CMS racing kart bumper. Call us today at 844-438-7244, we'll help you choose a powder color and get your CMS bumper on its way!
