TRAXXAS Unlimited Desert Racer Aluminum Front Knuckle Arms 6061-T6 UDR021 by GPM  [UDR021]

Machined aluminium knuckle arms for TRAXXAS UDR

This upgrade replaces the factory plastic front knuckles with machined aluminium knuckle arms made for the TRAXXAS Unlimited Desert Racer. The components move suspension and steering interfaces from molded plastic to 6061-T6 aluminium while using POM collars at bearing interfaces to maintain tight, repeatable bearing seating.

The knuckles stabilise the CVD joint and front suspension arms to promote consistent steering input over rough surfaces. Multiple tie-rod mounting holes let you refine steering geometry without swapping components, focusing on solid fit and repeatable performance rather than unnecessary complexity.

Fitting is straightforward for most hobby setups: remove the stock knuckles, press bearings into the aluminium knuckles using the tight tolerances for a secure fit, insert the POM collars to protect bearing surfaces, and fasten with the supplied hardware. The kit includes the screws and lock nuts referenced in the source so upper and lower attachment points and tie-rod ends can be secured without extra parts.

For hobbyists wanting crisper steering and improved bearing retention on TRAXXAS Unlimited Desert Racer builds, this machined aluminium knuckle arm set is a direct-fit upgrade that emphasises fit and stability.
