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

Rear aluminium knuckle upgrade

This aluminium rear knuckle arm is an aftermarket replacement for the TAMIYA Wild Willy 2 WR-02 chassis and is supplied as 1 pr. It replaces the factory plastic rear knuckle arms to give a metal option at the rear steering and suspension mounting points while keeping the original mounting geometry unchanged.

Installation follows the vehicle's normal rear hub and suspension steps; remove the stock knuckles, fit bearings and hubs in their existing positions on the chassis, then secure this aluminium unit using the original hardware. After fitting, cycle the suspension through its full travel and confirm there is no binding and that wheel alignment is correct.

For setup work this part provides a stiffer rear pivot compared with standard plastic arms, which can alter rear steering feel and suspension response. Fit it as a durable spare or when testing changes that reduce flex at the rear knuckle pivot.

A simple aluminium replacement that matches the Wild Willy 2 WR-02 layout and suits hobbyists replacing worn plastic knuckles or tuning rear-end stiffness during setup sessions.
