TRAXXAS UNLIMITED DESERT RACER Front upper suspension arm alloy replacement, by GPM UDR054  [UDR054]

Front upper suspension arm for TRX UDR

This alloy front upper suspension arm is an RC-scale replacement part designed for use with the TRAXXAS UNLIMITED DESERT RACER platform. It provides a firmer mounting point for the front knuckle assemblies and works with the vehicle's existing suspension geometry to reduce unwanted movement under load.

Construction uses aluminum 6061 T6 with Delrin collar inserts and stainless steel hardware provided in the kit, the arm is CNC machined and anodized to resist wear. The kit’s stainless steel balls and a screw-lock fastening method secure pivots against loosening during aggressive off-road runs.

In setup and tuning this arm is intended to increase front-end rigidity and consistency, which can help when adjusting camber, caster, or anti-squat through the rest of the suspension system. It installs at the stock front upper mounting points and is secured with the included stainless hardware.

As a direct-fit RC-scale upgrade, this arm focuses on stronger pivot support and stable front-end behaviour without changing core suspension geometry, making it suitable for hobbyists prioritizing durability and consistent handling on desert-style courses.
