RPM Black 1/5 Kraton/Outcast 8S BLX Rear Lower Suspension Arms

The ARRMA Kraton 8S is 26 lbs. (12kg.) of high-flying, dirt shredding, jump-killing fun! If your Aarms aren’t up to the abuse this massive monster can dish out, look no further than RPM.

RPM's 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, 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!

Compatibility: RPM do not recommend use of this product on thr EXB version of the 8s models. The EXB spring perch will cause fitment issues with the sway bar and lower shock mount, therefore requiring modification to the arms for proper fitment.
