TRAXXAS Revo / Revo 3.3 Alloy Rear Upper Arm by GPM TRV057RS  [TRV057RS]

Rear upper arm for TRAXXAS Revo

This is an RC-scale alloy rear upper arm designed for TRAXXAS Revo and Revo 3.3 chassis, supplied as a 1 pcs set 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.

Installation is straightforward for hobbyists familiar with suspension work: remove the wheel and existing arm, transfer or fit the included screws and pins, and verify suspension travel and alignment after assembly. Use appropriate hex drivers and inspect ball bearings and linkage points for wear during the swap.

In tuning terms this rear upper arm serves as a durable replacement that can slightly change rear suspension stiffness and response compared with stock components. It is intended for RC maintenance, track setup adjustments, and replacing damaged rear right upper arms on compatible Revo models.
