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

Rear aluminium knuckle arm for M1025 Hummer

This aluminium rear knuckle arm is an RC-scale replacement intended for Tamiya M1025 Hummer builds, model HM1022. It is offered as an aftermarket upgrade to replace stock plastic knuckles and to provide a more consistent mounting point for suspension linkages on compatible TA-01 and TA-02 chassis.

Fit this part when you want firmer knuckle support for setup or when replacing worn components during routine maintenance. The name and model identify this as an aluminium rear knuckle arm, so check alignment and toe settings after installation to restore accurate suspension geometry.

Installation notes and tuning role: remove the original knuckle, transfer bearings and hardware as required, install the aluminium knuckle in the same orientation, and verify wheel bearing preload and linkage angles before running the model.

Suitable for hobbyists seeking an aluminium rear knuckle for M1025 Hummer projects and for those tuning suspension response on compatible Tamiya chassis.
