TRAXXAS Revo / Revo 3.3 Alloy Rear Upper Arm by GPM TRV057LS  [TRV057LS]

Alloy rear upper arm for Revo

This aluminium alloy rear upper arm is a single-piece left-side replacement designed for TRAXXAS Revo and Revo 3.3 model RC trucks. The part uses a sandwich construction secured by screws and pins to retain bushings and connection points, and it replaces the factory plastic arm where higher stiffness or wear resistance is required.

Functionally, the arm locates the rear suspension pick-up and affects camber and toe behavior under load; as an aluminium component it alters flex and feedback compared with stock plastic arms, so expect a different feel when tuning suspension settings. The package supplies the arm for the left side along with the fastening screws and pins as indicated in the product title.

Installation notes: fit this arm using the provided screws and pins, verify alignment with the chassis and drive components, and check clearances around the shock mounts and driveshafts after installation. Use standard RC maintenance practices when replacing suspension links to ensure safe and reliable operation at scale.
