TRAXXAS Revo Alloy Rear Upper Arm Right Side TRV057RS by GPM  [TRV057RS]

Right rear upper arm for Revo series

This is an RC-scale alloy rear upper arm built for TRAXXAS Revo and Revo 3.3 chassis, supplied as a single piece for the right side. The part uses a sandwich-style aluminium construction secured with screws and pins to replace the stock plastic arm with a metal alternative intended for hobby use only.

Fitting is straightforward for anyone comfortable with suspension work: remove the wheel and the existing arm, fit or transfer the supplied screws and pins, and then check suspension travel and alignment after assembly. Use suitable hex drivers and inspect ball bearings and linkage points for wear during installation.

From a tuning perspective this rear upper arm gives a more robust replacement that can subtly change rear suspension stiffness and feedback compared with stock parts. It is intended for routine maintenance, setup adjustments at the track, and replacing a damaged right rear upper arm on compatible Revo models.
