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

Alloy front upper arm for TRX UDR use

This alloy front upper suspension arm is a scale replacement for the TRAXXAS UNLIMITED DESERT RACER chassis. It gives a firmer mounting position for the front knuckles and works with the stock suspension geometry to reduce unwanted movement under load.

Constructed from aluminum 6061 T6 with Delrin collar inserts and stainless steel hardware supplied in the kit, the arm is CNC machined and anodized for wear resistance. The kit includes stainless balls and a screw-lock fastening method to keep pivots secure during aggressive off-road running.

In tuning and setup this arm is intended to raise front-end rigidity and repeatability, which helps when adjusting camber, caster, or anti-squat across the suspension. It fits the stock front upper mounting points and is secured with the included stainless hardware.

As a direct-fit scale upgrade, this arm focuses on stronger pivot support and steadier front-end behaviour without altering core suspension geometry, making it suited to hobbyists who want reliable handling on desert-style courses.
