TRAXXAS Unlimited Desert Racer Aftermarket Front Knuckle Arms UDR021 by GPM  [UDR021]

Aftermarket aluminium front knuckles for TRAXXAS UDR

This upgrade converts the factory plastic front knuckles to machined aluminium knuckle arms intended for the TRAXXAS Unlimited Desert Racer. Steering and suspension interfaces are transitioned to 6061-T6 aluminium, with POM collars at bearing interfaces to preserve tight, repeatable bearing placement.

The design helps stabilise the CVD connection and front arm pivots so steering inputs remain consistent across bumpy terrain. Multiple tie-rod holes are provided to let you tune steering throw and geometry without part swaps, keeping adjustments simple and effective.

Installation is typical for hobby builds: remove the OEM knuckles, press bearings into the aluminium pieces using the precise tolerances, fit the POM collars to reduce wear, and fasten with the included hardware. The set contains the screws and lock nuts listed in the source so standard mounting points are covered.

If you want a straightforward, hardware-inclusive upgrade that tightens steering feel and bearing retention on TRAXXAS Unlimited Desert Racer models, this machined aluminium knuckle set is a practical choice.
