Wild Willy 2 WR-02 Rear Aluminium Knuckle Arm WW2022 for Tamiya by GPM  [WW2022]

Rear aluminium knuckle replacement

This aluminium rear knuckle arm is offered as a 1 pr aftermarket replacement for the TAMIYA Wild Willy 2 WR-02. It substitutes the original plastic rear knuckles with a metal unit while preserving the factory mounting geometry for direct fitment.

Fitting is straightforward following the vehicle's rear hub and suspension removal routine; take off the stock knuckles, place bearings and hubs as they sit on the chassis, then secure this aluminium arm with the original fasteners. Always move the suspension through its full range after installation to ensure smooth movement and correct alignment.

As a tuning option this arm provides a less compliant rear pivot compared with plastic parts, influencing rear steering and suspension feedback. Use it when you want a tougher replacement or to experiment with reduced rear knuckle flex during setup.

A practical aluminium upgrade that fits the Wild Willy 2 WR-02 layout, suited to hobbyists replacing tired plastic knuckles or testing changes to rear stiffness.
