TRAXXAS UNLIMITED DESERT RACER Aluminum Front Knuckle Arms 12 pcs by GPM UDR021  [UDR021]

Aluminum front knuckle arms for TRAXXAS UDR

This RC-scale upgrade replaces the stock plastic front knuckles with machined aluminum knuckle arms designed for the TRAXXAS Unlimited Desert Racer platform. The parts shift key suspension and steering interfaces from molded plastic to 6061-T6 aluminium while using POM collars where bearings interface, keeping bearing fit tight and repeatable.

Functionally the knuckle arms stabilise the CVD connection and front arms to assist consistent steering input across rough terrain. Multiple mounting holes for tie rods are provided to allow small changes in steering geometry without swapping parts. The design focuses on fit and repeatability rather than added complexity.

Installation is straightforward for common hobby setups: remove the stock knuckles, press bearings into the aluminum knuckles (the tight tolerances help bearings seat securely), fit the POM collars to protect bearings from wear, and secure with the supplied fasteners. The package includes the screws and lock nuts referenced in the source so you can mount upper and lower points and lock the tie-rod ends without sourcing extra hardware.

For hobbyists looking to increase steering precision and bearing retention on TRAXXAS Unlimited Desert Racer models, this machined aluminium knuckle arm set offers a direct, hardware-included upgrade that prioritises fit and stability over cosmetic change.
