CNC 6061-T6 aluminum front arms and knuckles for TRAXXAS UDR

This front upper and lower arm kit with matching knuckle arms is an aftermarket upgrade for the TRAXXAS Unlimited Desert Racer chassis. The assembly replaces stock plastic suspension pieces with CNC-machined 6061-T6 aluminum components combined with Delrin collars and POM elements where specified to tighten fit, sharpen steering feel, and increase durability for hard off-road use.

The design focuses on common service and tuning points of the UDR front end: knuckle arms stabilise the CVD axle and accurately locate the upper and lower arms to keep steering geometry consistent, while the curved arm profiles provide extra clearance to avoid contact with nearby parts. Fastening hardware uses stainless steel screws and steel balls at wear points to improve assembly robustness and reduce movement over time.

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

Fit this kit when you want firmer front suspension mounting points, reduced play at the knuckles, and a serviceable metal alternative to the factory plastic parts. Install with the correct thread locker and check alignment and fastener torque step by step.

Will these arms fit the factory UDR spindles?

Yes, the geometry and mounting points match the TRAXXAS Unlimited Desert Racer front end; verify your current CVD and axle setup during dry fit before final assembly.

How do the materials improve handling?

6061-T6 aluminum reduces flex at pivot points while Delrin collars and POM wear pieces keep tolerances tight, which leads to crisper steering response and steadier alignment under load.

Are extra parts required to install this kit?

The package contains the listed fasteners and pins; have hex drivers, a small torque driver, and medium-strength thread locker ready to secure screws during installation.

Will this change my steering setup tuning?

Yes, the stiffer mounting points reduce play and the multiple tie-rod holes allow finer steering geometry adjustments; recheck toe and camber settings after fitting to dial in handling.
