TRAXXAS Revo 3.3 Alloy Rear Upper Arm Left - TRV057LS by GPM  [TRV057LS]

Left aluminium rear upper arm for Revo models

This single-piece aluminium alloy rear upper arm is a direct left-side replacement built for TRAXXAS Revo and Revo 3.3 trucks. The sandwich-style construction is secured with screws and pins to retain bushings and attachment points, replacing the stock plastic arm when you need greater stiffness and wear resistance.

In use the arm establishes the rear suspension pick-up and influences camber and toe under load; as an aluminium link it changes flex and steering feedback compared with the factory plastic, so suspension tuning will feel different. The package includes the left arm plus the fastening screws and pins listed in the product title.

Fitment notes: install the arm using the supplied screws and pins, confirm chassis alignment and free play at driveshafts, and verify clearances around shock mounts after assembly. Follow standard RC maintenance routines after replacing suspension links to ensure safe running.
