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

Aluminium rear knuckle arm for M1025 Hummer

This aluminium rear knuckle arm is an RC-scale replacement part produced for TAMIYA M1025 Hummer applications by GPM, model HM1022. It is intended as an aftermarket upgrade to replace equivalent plastic knuckles and to give a more consistent mounting point for suspension linkages on compatible Tamiya platforms.

Use this part when you need firmer knuckle support for setup work or when replacing worn components during routine maintenance. The text and fitment information in the product name identify the part as aluminium and as a rear knuckle arm, so assess alignment and toe settings after installation to restore suspension geometry.

Installation notes, general considerations, and tuning role, without altering original chassis geometry: remove the stock knuckle, transfer bearings and fasteners as required, fit this aluminium knuckle in the same orientation, and verify wheel bearing preload and linkage angles before running the model.

This part is suited for hobbyists who want an aluminium replacement knuckle for M1025 Hummer builds and for those tuning suspension response on compatible Tamiya chassis.
