The ARRMA Kraton 8S & Outcast 8S are 26 lbs. (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 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. 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!
