TRAXXAS Unlimited Desert Racer Aluminum Front Upper & Lower Arms + Knuckle Arms by GPM UDR2154A55  [UDR2154A55]

Aluminum front arms and knuckles for TRAXXAS UDR

This aluminum front upper and lower arm set with knuckle arms is an aftermarket upgrade produced by GPM for the TRAXXAS Unlimited Desert Racer chassis. The kit replaces standard plastic front suspension components with CNC-machined 6061-T6 aluminum parts combined with Delrin collars and POM elements where specified to improve connection fit, steering response, and durability under RC off-road use.

Design highlights address common service and tuning points on the UDR front end: knuckle arms stabilize the CVD axle and locate the upper and lower suspension arms for consistent steering geometry, while the curved suspension arm profiles provide clearance to avoid contact with nearby components. Fastening uses stainless steel screws and steel balls where noted to secure wear points and improve assembly robustness.

Use this kit when you need stronger front suspension mounting points, reduced play at knuckles, or a more serviceable metal alternative to the factory plastic pieces. It is intended for RC-scale upgrades only and should be installed with appropriate thread locking and step-by-step checking of alignment and fastener torque.
