Black Front A-Arms for Boost/Circuit/Ruckus/Torment (2) (RPM70582)

Black front A-arms (two-arm set) for 2WD ECX Ruckus, Torment, and Circuit vehicles replace the stock front suspension with a stronger, tighter-tolerance setup designed to help lock in suspension settings and improve handling on rough terrain.

Made from a tough engineering-grade nylon blend, these RPM front A-arms feature angled leading and trailing edges for better aerodynamics and smoother transitions over obstacles. Reinforced around the hinge pins reduces wear from big hits, and an inline outer hinge-pin locking screw keeps the pins secured in place. They’re backed by a limited lifetime warranty against breakage.
