TRAXXAS E-REVO Rear Upper Arm Alloy TRV057 by GPM  [TRV057]

Heavy-duty alloy rear upper arm for E-REVO

This rear upper arm is an RC replacement part made for the TRAXXAS Revo family. It employs an alloy sandwich configuration and is supplied complete with screws, pins and Delrin collars for installation, delivered as a 1pr set. The sandwich configuration clamps the arm between two alloy plates to limit flex where the load transfers to the suspension mounts.

As a direct replacement piece, the arm restores worn link geometry and establishes a firmer attachment point for the rear suspension, helping to maintain alignment when subjected to heavier loads or upgrades. The Delrin collars act as low-friction guides around pivot pins, reducing wear on adjacent plastic parts.

Use this alloy upper arm to replace degraded plastic links or to tighten the rear suspension mount; verify pin and screw compatibility with your chassis and perform a dry fit to check clearance.
