Aluminium rear knuckle for Tamiya M1025 Hummer

This aluminium rear knuckle arm is an RC-scale replacement for Tamiya M1025 Hummer builds, identified as model HM1022. It serves as an aftermarket swap for the factory plastic knuckle to provide steadier mounting points for your suspension links on TA-01 and TA-02 compatible chassis.

Use this arm when firmer knuckle support is needed for setup or when replacing worn parts during routine servicing. Because the part is aluminium, make sure to recheck alignment and toe settings after installation to preserve correct suspension geometry.

Installation guidance: remove the original knuckle, carry over bearings and fasteners where needed, fit this aluminium knuckle in the same orientation, and confirm wheel bearing preload and linkage angles before running the model.

Specifications

  • Item: Tamiya M1025 Hummer Aluminium Rear Knuckle Arm
  • Material: Aluminium
  • Model Number: GPM HM1022
  • Compatibility: Tamiya M1025 Hummer, TA-01/TA-02

Ideal for modelers wanting an aluminium knuckle for M1025 Hummer projects and for those adjusting suspension response on compatible Tamiya platforms.

Will this replace the stock rear knuckle without modification?

In most cases the fit is direct on standard M1025 rear mounts. Verify your chassis variant and transfer bearings to ensure correct axle spacing.

Are extra tools required to fit this part?

No special tools are needed beyond standard hobby tools for removing the old knuckle and refitting bearings and fasteners.

Does aluminium affect alignment stability?

The increased stiffness of aluminium helps keep linkage geometry more consistent under load, which can aid stable alignment during tuning.

Any final assembly tips?

After fitting, check bearing preload and ensure hub hardware is torqued correctly, then adjust toe and camber to your setup targets.
