Blue Upper and Lower A-Arms for X-Maxx (2) (RPM82355)

Blue upper and lower A-arms for the Traxxas X-Maxx provide a sturdy, lighter upgrade over the stock arms. This RPM set is molded from engineering-grade nylon and finished in vivid blue, delivering enhanced durability to handle the weight and punishment of big-truck abuse without adding unnecessary heft.

Each package includes one upper and one lower A-arm, and four packages are typically needed to complete a full X-Maxx. The arms are a universal fit, so orientation doesn’t matter when swapping them in on any corner of the truck. They’re designed to be stronger and lighter than stock, with a robust lower-arm design featuring a double support beam to spread impact energy across a larger area for improved resilience. Made in the USA, RPM X-Maxx A-arms are backed by a limited lifetime warranty against breakage.
