Engineered aluminium front arm and knuckle assembly for TRAXXAS UDR

The UDR2154A55 front arm and knuckle kit is a precision aftermarket upgrade for the TRAXXAS Unlimited Desert Racer chassis. Major structural parts are CNC-machined from 6061-T6 aluminium with Delrin collars and POM wear inserts at pivot interfaces to control radial play and maintain tight tolerances under load.

Design features focus on functional improvements: knuckle arms mechanically locate the CVD axle and define upper and lower arm geometry for repeatable steering alignment, while contoured arm profiles are shaped to prevent interference with adjacent suspension components. Fastening hardware utilises stainless steel screws and steel balls at high-stress locations to reduce fretting and improve joint longevity.

Specifications

  • Item Front upper & lower arms and knuckle arms set, 28 pcs
  • Material 6061-T6 aluminum, Delrin collars, POM components, stainless steel fasteners
  • Model Number UDR2154A55
  • Compatibility TRAXXAS Unlimited Desert Racer

Intended for hobbyists seeking a precision metal replacement for OEM plastic components, this kit improves pivot stiffness and serviceability; install using recommended torque values and thread locker where specified.

Does the kit retain stock mounting geometry?

Yes, mounting points are engineered to match the TRAXXAS Unlimited Desert Racer geometry while tightening tolerances to reduce slop at pivots.

What manufacturing methods are used?

Components are CNC-machined from 6061-T6 billet where specified, with Delrin and POM used at wear interfaces to balance stiffness and low-friction movement.

How should I verify fit during installation?

Perform step-by-step assembly, hand-check pivot clearance, apply medium-strength thread locker to metal screws, and torque to recommended values while monitoring steering travel for binding.

Are replacement wear components available?

Delrin collars and POM inserts are designed as replaceable wear items; inspect these during maintenance cycles and replace them to retain original fit and performance.
