TAMIYA M1025 Hummer Aftermarket Aluminium Front Knuckle HM1021 by GPM  [HM1021]

Aftermarket aluminium knuckle for improved steering stability

This aluminium front knuckle is an aftermarket replacement tailored for the TAMIYA M1025 Hummer and is supplied as GPM HM1021. The machined aluminium item replaces the stock plastic knuckle to provide a firmer steering mount and reduce unwanted movement under load.

Compatibility is confined to the TAMIYA M1025 Hummer platform and the TA-01 and TA-02 chassis listed in the specifications section below. Installing this knuckle involves removing the original component and refitting the aluminium part using the vehicle's current hardware. Pay attention to proper thread engagement and moderate torque to preserve aluminium mating surfaces.

Fit this knuckle when you want a more predictable steering feel or when upgrading to metal components for routine use. It is a structural upgrade and does not change electronic or motor settings.
