TRAXXAS Revo Alloy Rear Upper Arm TRV057 by GPM  [TRV057]

Reinforced alloy rear upper arm for Revo range

This rear upper arm is an RC-scale replacement designed specifically for the TRAXXAS Revo family. The part uses an alloy sandwich layout and is supplied with the matching screws, pins and Delrin collars needed for installation, provided as a 1pr set. The sandwich layout traps the arm between two alloy plates to reduce flex where the hardware meets the suspension mounts.

Fitted as a direct replacement, this arm helps restore worn link geometry and gives a firmer mounting point for the rear suspension, helping to keep alignment under heavier loads or after drivetrain upgrades. The Delrin collars act as low-friction spacers around pivot pins, cutting wear on mating plastic parts and helping maintain smooth movement.

Replace aged plastic upper links with this alloy arm to reduce deflection and preserve rear geometry; check pin and screw sizes against your chassis and do a test fit to confirm clearance.
