Quick Notes:- Sold in pairs

- Optional Mud Guards are also available
The ARRMA Kraton 8S & Outcast 8S are 12kg of high-flying, dirt shredding, jump-killing fun! If your A-arms aren’t up to the abuse this massive monster can dish out, look no further than RPM. Our 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 15.8mm tall x 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. We also moved the inner cross brace away from the chassis, eliminating the droop stop entirely. While this may seem counter-intuitive, our test truck’s 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 our trademark blend of ultra durable materials, you can’t go wrong with RPM!
Version Notes: RPM A-arms work perfectly with 8S versions of the Kraton & Outcast using ARRMA 330569 Spring Perches. EXB models using ARRMA 330740 Spring Perches may experience interference issues at both the shock mount and sway bars. RPM does not recommend the use of our a-arms on these vehicles since modification of the a-arms may be necessary to eliminate bind at the shocks and sway bars.
Tech Notes: RPM Rear A-arms for the ARRMA Kraton 8S are sold as a pair. RPM A-arms replace stock ARRMA ARA330590.
