This RC-scale alloy rear upper arm is engineered for TRAXXAS Revo and Revo 3.3 chassis, supplied as a single right-side unit. The component employs a sandwich-style aluminium construction secured with screws and locating pins to replace the OEM plastic arm and is intended for hobby and upgrade use only.
Installation requires standard suspension skills: remove wheel and existing arm, install the provided fixings or transfer original hardware, and verify suspension articulation and alignment post-fitment. Use correct hex drivers and inspect ball joint tolerances and linkage bearings during assembly to ensure smooth operation.
From a performance and durability standpoint the aluminium arm delivers improved resistance to impact and can subtly modify rear suspension stiffness and kinematics compared with stock components. It is suitable for maintenance, setup tuning, and replacing a damaged right-side rear upper arm on compatible Revo chassis.
