TRAXXAS Revo Alloy Rear Upper Arm Left Side Upgrade - TRV057LS by GPM  [TRV057LS]

Aluminium left rear upper arm for Revo series

This aluminium alloy rear upper arm is a single-piece replacement for the left side of TRAXXAS Revo and Revo 3.3 trucks. Its sandwich construction uses screws and pins to hold the bushings and connection points firmly, offering an upgrade over the original plastic arm when extra rigidity or longer wear life is required.

The arm sets the rear suspension pick-up and will affect camber and toe response under load; as an aluminium component it reduces flex and alters chassis feedback compared to plastic, so expect a different tuning feel when adjusting suspension settings. The shipment contains the left arm plus the fastening screws and pins described in the product title.

Installation advice: assemble using the supplied screws and pins, check alignment with the chassis and driveline, and confirm no interference with shock mounts or drive axles after fitting. Carry out routine maintenance checks following replacement.
