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

Left-side aluminium rear upper arm for Revo trucks

This single-piece aluminium rear upper arm is tailored as a left-side replacement for TRAXXAS Revo and Revo 3.3 RC trucks. The sandwich-style build is secured with screws and pins to hold bushings and mounting points in place, intended to replace the factory plastic arm when you need improved stiffness and longevity.

As the arm establishes the rear suspension pickup it has a direct effect on camber and toe under load; the aluminium construction changes flex characteristics and steering feedback versus the stock plastic arm, so expect a noticeably different response when setting up the suspension. The package contains the left arm with the required screws and pins as noted in the product title.

Fitment tips: use the supplied screws and pins for installation, confirm alignment with the chassis and driveline components, and check clearances around shocks and driveshafts once installed. Perform routine checks after the first runs.
