TAMIYA M1025 Hummer Stiff Aluminium Front Knuckle Arm HM1021 by GPM  [HM1021]

Stiffened aluminium knuckle for consistent steering

This aluminium front knuckle is supplied as an aftermarket upgrade for the TAMIYA M1025 Hummer and is sold under GPM part HM1021. It replaces the factory plastic knuckle to provide a more rigid mounting point for the steering linkage and to limit movement under load.

The knuckle is compatible with the TAMIYA M1025 Hummer platform and the TA-01 and TA-02 chassis types listed in the specifications. Fitting requires basic disassembly of the front suspension and steering linkage, removal of the OEM knuckle, and refitting the aluminium unit with the vehicle's existing fasteners. Be mindful of aluminium thread properties and set torque accordingly.

Ideal for drivers who want a firmer steering feel or who are swapping plastic parts for metal to take a higher running schedule. This part alters mechanical stiffness only and will not change any electronic settings or motor performance parameters.
