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

Precision alloy rear upper arm for Revo family

This rear upper arm is a scale replacement made for TRAXXAS Revo vehicles. It adopts an alloy sandwich layout and ships with matching screws, pins and Delrin collars for fitment, supplied as a 1pr set. The sandwich layout positions the arm between two alloy plates to limit flex where hardware interfaces with the suspension mounts.

Installed as a like-for-like replacement, the component restores correct link geometry and gives a firmer mounting point for the rear suspension, which helps keep alignment under load or after upgrades. Delrin collars act as low-friction spacers around pivot pins to reduce wear on mating plastic components.

Choose this alloy rear upper arm when replacing worn plastic links or when you need a firmer rear mount; confirm pin and screw sizes against your chassis and perform a trial assembly to check clearance.
