TRAXXAS Unlimited Desert Racer Front Knuckle Arm Set 12 pcs UDR021 by GPM  [UDR021]

Replacement aluminium knuckles for TRAXXAS UDR

This aftermarket set replaces the standard plastic front knuckles with machined aluminium knuckle arms tailored for the TRAXXAS Unlimited Desert Racer chassis. The parts move steering and suspension contact points to 6061-T6 aluminium and use POM collars at bearing interfaces to keep bearing seating accurate and protected.

The knuckles support the CVD junction and front arm mounts to maintain steady steering behaviour across uneven terrain. A selection of tie-rod mounting holes provides easy adjustment of steering geometry without the need to swap components, keeping the upgrade practical and tuning-friendly.

Fitting requires typical workshop steps: remove the OEM knuckles, press bearings into the aluminium knuckles where the tight tolerances ensure a solid fit, fit the POM collars to protect bearing surfaces, and secure everything with the included fasteners. The pack contains the screws and lock nuts referenced in the source for standard mounting and tie-rod locking.

For modelers focused on reliable steering performance and bearing security on TRAXXAS Unlimited Desert Racer kits, this machined aluminium knuckle arm set offers a durable, hardware-included upgrade.
