Aluminum front gearbox for Tamiya Hotshot family

This aluminum front gear box is an RC-scale replacement part designed for TAMIYA Hotshot, Super Hotshot, Boomerang and Bigwig chassis. It is intended as a direct-fit hop-up to replace the stock plastic housing with a more rigid metal shell to reduce flex under load and improve gear alignment during demanding driving.

Compatibility is limited to the specific models listed, and the unit is supplied in a gun metal finish. The text highlights fitment and installation effects rather than performance claims; this part is intended for hobbyist use on model-grade transmissions only.

Specifications

  • Item: Front Gear Box
  • Material: Aluminum
  • Model Number: JR-THS12-GU
  • Compatibility: Tamiya Hotshot / Super Hotshot / Boomerang / Bigwig

Choose this aluminum front gear box when you want a firmer front-end housing for routine maintenance or incremental drivetrain tuning; always verify fitment against your chassis before final installation.

Is this a direct replacement for the stock plastic front housing on Hotshot models?

The design targets a direct-fit replacement for the listed TAMIYA models. However, check screw alignment and mating faces on your chassis before final assembly to confirm there are no small trim or spacer requirements.

Will I need to change gear mesh or add shims after fitting the aluminum housing?

Because the housing is stiffer than the original plastic, minor gear-mesh checks and small shim adjustments are recommended during installation to ensure correct engagement and to avoid premature wear.

Any special hardware or threadlocker recommended when installing?

Use the correct screw sizes for your chassis and consider a small amount of medium-strength threadlocker on fasteners where appropriate. Recheck fastener torque after a short run-in period.

Does the package include internal gears or bearings?

The listing describes an aluminum front gear box housing. Confirm with your supplier whether gears or bearings are included, as some packages provide housing only.
