Black Front Left Upper and Lower Suspension Arms for Arrma 8S (2) (RPM81522)

Black front upper and lower A-arms for ARRMA 1/5 Kraton and Outcast replace the factory front suspension arms to deliver greater durability and steadier handling on rough terrain. Each kit consists of one upper and one lower arm, and two kits are typically needed to fully outfit the front end—one for each side.

Lower arms use a triple-beam design to spread impact energy across three beams, while upper arms use a dual-beam layout for added strength. The inner cross brace is moved away from the chassis to eliminate the droop stop and protect the chassis during big landings. The arms are lighter than stock by about 4.5 grams per arm pair and are molded from RPM's durable USA-made material. They replace the stock A-arms on 8S Kraton and Outcast models; compatibility notes indicate that some EXB variants with certain spring perches may experience interference at shock mounts or sway bars and could require modification to avoid binding. The kit includes finger-nail slots for easy access to remove the aluminum pivot-ball ring (not included).
