TRAXXAS UNLIMITED DESERT RACER Front Upper Arm Performance Alloy UDR054 by GPM  [UDR054]

Front upper arm designed for TRX UDR

This alloy front upper suspension arm serves as an RC-scale replacement suited to the TRAXXAS UNLIMITED DESERT RACER. It reinforces the mounting area for the front knuckles and reduces flex that can alter steering under load.

Manufactured from aluminum 6061 T6 with Delrin collar inserts and provided stainless steel hardware, the arm is CNC machined and anodized to resist scuffing and wear. Supplied stainless balls and screw-lock fastening are used to secure pivots during heavy off-road use.

During setup the arm is intended to boost front-end rigidity and consistency, helping with camber and caster adjustments while retaining the vehicle's stock suspension geometry. It installs at the factory front upper points and uses the supplied stainless hardware.

As a direct-fit upgrade, the arm prioritises pivot strength and steady front handling without altering core suspension geometry, suited to hobbyists wanting durable, predictable behaviour on desert runs.
