TRAXXAS Rustler VXL 1/10 Front Upper Arm by GPM RUS054  [RUS054]

Front upper arm for Rustler VXL

This alloy front upper arm is an aftermarket replacement designed for TRAXXAS 1/10 Rustler VXL chassis as produced by GPM under model RUS054. It is supplied as a single pair meant to replace the original upper arm components, retaining the same mounting points and basic geometry so it can be installed using the chassis' factory hardware.

Installation notes: remove the wheel and steering linkage to access the upper arm mounting pins, use the original hex screws and retainers where applicable, and confirm ball cup alignment before final tightening. Basic hand tools and a hex driver are sufficient for fitment; verify steering travel and suspension droop after installation to prevent binding.

Tuning role: swapping plastic upper arms for alloy parts changes the stiffness at the front upright junction, which can slightly affect steering feedback and suspension response. Use this arm when you need a metal replacement for maintenance or when experimenting with small changes to steering geometry and suspension feel; check toe and camber after installation and adjust toe links or camber links as required.

Use this arm when replacing worn front upper arms or when testing minor changes to front-end stiffness; follow standard setup checks after installation to ensure proper steering and suspension operation.
