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

Precision rear knuckle arm

This aluminium rear knuckle arm is an aftermarket replacement supplied as 1 pr for the TAMIYA Wild Willy 2 WR-02 chassis. It replaces the stock plastic knuckles with a metal option while maintaining the original mounting geometry for direct fitment with standard hubs and bearings.

Installation follows the standard rear hub and suspension workflow: remove the factory knuckles, fit bearings and hubs in their original positions on the chassis, then secure the aluminium arm with the existing hardware. Verify full suspension travel and clearances after fitting to ensure correct articulation and to prevent binding.

Functionally this arm reduces compliance at the rear knuckle pivot compared with plastic parts, which can influence rear steering feel and the vehicle's suspension response. It is suitable as a durable spare or for experimental setups where reduced knuckle flex is desired.

A practical aluminium upgrade for the Wild Willy 2 WR-02 layout, aimed at hobbyists looking for improved durability and a firmer rear pivot during setup work.
