Precision-engineered aluminium knuckle for WR-02

This RC-scale aluminium front knuckle arm is engineered for the Tamiya Wild Willy 2 WR-02 chassis and supplied as 1pr. The CNC-machined component replaces the stock plastic knuckle arm and is designed to provide improved pivot stability and repeatable steering geometry while preserving the factory chassis mounting pattern.

Produced from machined aluminium to WR-02 specification mounting points, the knuckle arm focuses on dimensional accuracy, durability under repeated loading, and consistent steering response. It is intended for use in maintenance cycles, part replacement, and incremental tuning where reduced flex at the steering pivot is required.

Technical installation notes: removal of the front hub carrier and associated pins and screws on the WR-02 is required to install this arm. Use serviceable original hardware when possible, ensure correct pin retention, and verify bearing alignment and endplay during reassembly to maintain steering precision and full suspension travel.

Specifications

  • Item: Front Knuckle Arm - 1pr
  • Material: Aluminium
  • Model Number: GPM WW2021
  • Compatibility: Tamiya Wild Willy 2 WR-02

A precision upgrade for hobbyists seeking a CNC-machined alternative to plastic knuckles, offering repeatable pivot behaviour and improved durability in WR-02 applications.

What dimensional checks should I perform before fitment?

Measure mounting hole spacing and compare to WR-02 references, confirm hub carrier clearance, and inspect bearing bore concentricity prior to final assembly.

Are torque settings different for aluminium versus plastic knuckles?

Use moderate torque and avoid over-tightening; aluminium is stiffer so follow recommended fastener torque for WR-02 hardware and recheck after initial runs.

Can this knuckle arm be used with aftermarket hubs?

Compatibility is based on hub and carrier dimensions; verify any larger aftermarket hubs for clearance and adjust hardware as required.

What are the recommended inspection intervals?

Inspect pin retention, bearing condition, and fastener torque after the first few runs and then as part of regular maintenance cycles to ensure consistent steering performance.
