Precision machined aluminium knuckle arms for TRAXXAS UDR

This machined aluminium knuckle arm set replaces stock plastic knuckles on TRAXXAS Unlimited Desert Racer chassis, relocating key steering and suspension interfaces to 6061-T6 aluminium while employing POM collars at bearing locations to protect contact surfaces and ensure consistent seating.

Designed with repeatable fit and mechanical stability in mind, the knuckles reinforce the CVD connection and front arm pivots to reduce unwanted movement under load. Multiple tie-rod mounting holes permit fine adjustment of steering geometry without changing parts, prioritising practical tuning over excess complexity.

Installation follows standard hobby procedures: remove OEM knuckles, press bearings into the aluminium knuckles using the engineered tolerances, fit the POM collars to reduce wear, and secure with the supplied fasteners. The kit includes the screws and lock nuts listed in the source so assembly covers upper and lower mounting points and tie-rod fixation.

Just received Avery well packed and vey shiny box of GPM parts... all look great... only one negative... and probably on my part... the discs and calipers come in sets of 4... not 4 discs or 4 calipers.. oh well another order to follow... great service th

Are these designed for direct replacement on UDR chassis?

Yes, the knuckles are intended as a direct replacement for the stock front knuckles on TRAXXAS Unlimited Desert Racer vehicles and are dimensioned for direct fit.

What materials and interfaces are specified?

The arms are 6061-T6 aluminium and the bearing collars are POM, providing a metal structural interface with polymer protection at bearing contact points.

How do the tolerances affect bearing fit?

Tight tolerances are used so bearings press-fit securely into the knuckles, and the POM collars maintain repeatable seating and reduce material wear at the interface.

Is additional hardware required for installation?

No extra hardware is normally needed; the supplied screws and lock nuts referenced in the source allow you to mount and lock the knuckles and tie-rod ends.

Can steering geometry be tuned with these knuckles?

Yes, multiple tie-rod mounting locations permit incremental changes to steering throw and geometry without swapping components.
