Precision CNC-style knuckle for sharper steering feedback

This aluminium front knuckle is an aftermarket replacement for the TAMIYA M1025 Hummer, offered under part number GPM HM1021. The machined metal part stiffens the steering pickup area compared to the original plastic piece, improving consistency under load.

Compatibility is specific to the TAMIYA M1025 Hummer and the TA-01 and TA-02 chassis platforms listed below. Installation involves front suspension and linkage disassembly to remove the stock knuckle and refit the aluminium unit using the existing hardware. Observe correct thread engagement and avoid excessive torque on aluminium mating surfaces.

The knuckle is useful for setup work when evaluating steering feel or moving to metal components for durability. It is a mechanical upgrade only and does not affect electronic calibration or motor/ESC settings.

Specifications

  • Item: Tamiya M1025 Hummer Aluminium Front Knuckle Arm
  • Material: Aluminium
  • Model Number: GPM HM1021
  • Compatibility: TA-01 / TA-02

Is this knuckle a direct replacement?

Yes, it is designed as a replacement for the original knuckle on compatible TA-01 and TA-02 M1025 Hummer chassis, but confirm your chassis code before fitting.

Any special tools required?

Basic hobby tools are sufficient: hex drivers and pliers for disassembly and reassembly. Use correct torque and hand-tighten where appropriate to protect threads.

Will it improve durability?

Switching from plastic to aluminium reduces flex and increases resistance to repeated impacts, giving better longevity for frequent running.
