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

Durable aluminium knuckles for TRAXXAS UDR

This replacement set swaps the stock plastic front knuckles for machined aluminium knuckle arms built for the TRAXXAS Unlimited Desert Racer platform. The design transfers steering and suspension interfaces to 6061-T6 aluminium and uses POM collars where bearings sit to maintain a precise, wear-resistant interface.

Functionally the knuckles add rigidity to the CVD joint and front suspension pivots, helping the steering track more consistently over rough ground. Multiple tie-rod mounting points allow small steering geometry adjustments without additional parts, keeping the focus on reliable fit and straightforward tuning.

Installation follows common hobby procedures: remove original knuckles, press bearings into the aluminium parts using the designed tolerances, fit the POM collars to reduce bearing wear, and secure with included fasteners. The kit lists screws and lock nuts so no extra hardware should be necessary for standard setups.

For builders seeking a practical steering upgrade on TRAXXAS Unlimited Desert Racer machines, this machined aluminium knuckle set improves bearing retention and steering consistency without extra complexity.
