Tamiya M1025 Hummer Rear Knuckle Arm Aluminium HM1022 by GPM  [HM1022]

Rear knuckle arm in aluminium for M1025 Hummer

This aluminium rear knuckle arm is an RC-scale replacement for the Tamiya M1025 Hummer, carrying the model number HM1022. It is intended as an aftermarket upgrade to swap out the original plastic knuckle and provide a steadier mounting point for suspension linkages on compatible TA-01 and TA-02 chassis.

Fit this component when you need firmer knuckle support during setup or when replacing worn hardware. The product title and model indicate this is an aluminium rear knuckle arm, so recheck alignment and toe after installation to keep suspension geometry correct.

Fitting notes: remove the stock knuckle, move bearings and fasteners across as required, fit this aluminium knuckle in the same orientation, and confirm wheel bearing preload and linkage angles before running the vehicle.

A practical upgrade for modellers wanting an aluminium rear knuckle for M1025 Hummer builds or for those refining suspension behaviour on compatible Tamiya chassis.
