Precision Rear Upper Arm TRV057 for TRAXXAS Revo by GPM  [TRV057]

Alloy rear upper arm for Revo series

This rear upper arm is an RC-scale replacement part designed for the TRAXXAS Revo family. The component uses an alloy sandwich layout and ships with the matching screws, pins and Delrin collars required for fitment, supplied as a 1pr set. The sandwich design locates the arm between two alloy plates to reduce flex where the hardware interfaces with the suspension mounting points.

In practice this arm serves as a direct replacement to restore worn or damaged link geometry and to provide a firmer mount point for the rear suspension, helping preserve alignment under higher loads or after upgrades. The included Delrin collars act as low-friction spacers where pivot pins pass through, reducing wear on mating plastic parts.

Use this alloy rear upper arm when replacing aged plastic links or when aiming for a firmer rear suspension mount; verify pin and screw sizes on your chassis before installation and perform a test fit to confirm clearance.
