TRAXXAS Rustler VXL Rear Upper Arm Alloy Upgrade RUS057 by GPM  [RUS057]

Upgraded alloy rear upper arm for Rustler VXL

This alloy rear upper arm is an aftermarket replacement manufactured by GPM as item RUS057 for the TRAXXAS 1/10 Rustler VXL platform. It serves as a direct-fit rear upper link to renew or upgrade the suspension pickup points and preserve alignment when the car is loaded.

Installation uses the Rustler VXL rear chassis mounting points and generally reuses existing hardware and pivot locations. Inspect ball studs and pivot pins for wear, and check clearances around the shock towers and rear hub during the first fit to avoid binding.

From a setup perspective the rear upper arm influences roll center and rear toe under compression and rebound. Fitting a stiffer alloy arm reduces flex at the pickup and helps keep rear geometry stable during hard cornering or fast runs. Make small incremental changes when altering other rear link lengths or shock rates to retain predictable handling.

Choose this arm when you need a robust aftermarket rear upper arm to stabilise rear suspension geometry for both track use and bashing sessions.
