Robust aluminum front gearbox for Tamiya chassis

This front gear box is an aluminum replacement part created for TAMIYA Hotshot, Super Hotshot, Boomerang and Bigwig frames. The metal housing replaces the weaker plastic original to give a tougher front drivetrain shell that transfers less flex into the gear set during high-stress runs.

Compatibility is restricted to the models listed above and the finish is gun metal. The description concentrates on durability and installation considerations and does not make performance guarantees; intended for model-grade transmissions and hobbyist maintenance.

Specifications

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

Use this aluminium front gear box when you need improved structural strength for routine upkeep or to limit drivetrain flex; always check fitment and clearances on your specific chassis before tightening fasteners.

How does the aluminum housing affect crash resistance?

The aluminum shell offers greater rigidity than the stock plastic, which can reduce deformation under load but may also transmit more shock to internal components. Regular inspection after impacts is advised.

Is corrosion a concern with the gun metal finish?

The gun metal finish provides surface protection, but avoid prolonged exposure to corrosive environments and clean and dry the unit after wet runs. Light maintenance will preserve appearance and fitment.

Will the stiffer housing increase wear on internal gears?

A stiffer housing reduces flex but can change load distribution; check gear mesh and bearing play after installation and during service intervals to monitor wear patterns.

What routine checks should I do after fitting the part?

Verify bolt torque, confirm gear mesh, and inspect bearings and seals for debris. Repeat checks after the first few runs to ensure nothing has settled loose or worn unusually.
