TRAXXAS MINI XRT VXL 3S 7075 Alloy Rear Upper Suspension Arms by GPM XRTM057  [XRTM057]

Rear upper suspension arm for Mini XRT

This 7075 alloy rear upper suspension arm is designed for the TRAXXAS MINI XRT VXL 3S as a direct hop-up to support the chassis and stabilise the rear hub stub axle carriers. The arm replaces the stock plastic link with a machined aluminium component to maintain alignment under load and reduce flex where the rear upper link mounts to the hub area.

Installation follows standard rear arm replacement steps, fit the rear upper suspension arm into the rear arm mounting location, insert the outer arm pin specified at 34.2mm through the arm and hub carrier, then secure with the M3 lock nut supplied. The package includes the arm pair and the mating pins and nuts needed for fitment so no additional hardware is required when used on the listed chassis.

The part is intended as an RC-scale chassis upgrade for better rear-end consistency during acceleration and cornering, and it functions as a tuning option when adjusting rear roll centre and link stiffness with complementary hardware and shock setup.

Use this aluminium rear upper arm when you need a firmer rear link mounting point to reduce movement in the hub carrier under load, while keeping installation straightforward with the included pins and lock nuts.
