RPM Arrma Kraton 8S Rear Suspension Arms are a heavy duty upgrade for the Arrma Kraton 8S & Outcast 8S models. These 26 lbs, high-flying, dirt shredding, jump-killing machines are true monsters. If your A-arms aren’t up to the abuse this massive rig can dish out, look no further than RPM. These replacement rear A-arms are designed with the backyard basher in mind and can handle some serious abuse and come back for more.

RPM rear A-arms have a triple beam style construction designed to spread impact energy across all three beams. Each beam’s cross-section is a whopping 5/8” (15.8mm) tall x 3/8” (9.5mm) wide. These massive beams reduce unwanted flex during normal suspension movement, yet allow impact-absorption during those not-so-perfect landings and crashes. RPM also moved the inner cross brace away from the chassis, eliminating the droop stop entirely. While this may seem counter-intuitive, the RPM test truck chassis was bent at the droop stops, clearly illustrating that extreme impacts were too much for the chassis plate to handle. After all, there’s nothing worse than a bent chassis.

Made in the USA from RPM's trademark blend of ultra durable materials, you can’t go wrong with RPM!
