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

Rear aluminium knuckle arm

This aluminium rear knuckle arm is an aftermarket replacement produced by GPM for the TAMIYA Wild Willy 2 WR-02 chassis and is supplied as 1 pr. It replaces the factory rear knuckle arms to provide a metal alternative for the rear steering/suspension mounting points without altering the original mounting geometry.

Installation follows the vehicle's standard rear hub and suspension procedure; remove the stock knuckles, fit bearings and hubs as they sit on the chassis, then secure this aluminium unit with the original hardware. Verify alignment and movement through full suspension travel after fitting to confirm there is no binding.

In tuning terms this part serves as a rigid option compared with standard plastic components, affecting rear steering feel and suspension response. Use it when you need a durable spare or when exploring setup changes that rely on reduced flex at the rear knuckle pivot.

As a straightforward aluminium replacement, this GPM part fits the Wild Willy 2 WR-02 layout and is suitable for hobbyists replacing worn plastic knuckles or testing changes to rear-end stiffness during setup work.
