Aluminum front gearbox designed for Tamiya chassis

This aluminum front gear box serves as an RC-scale replacement for TAMIYA Hotshot, Super Hotshot, Boomerang and Bigwig chassis. It replaces the factory plastic housing with a more rigid metal unit to limit flex and help maintain gear alignment when the model is driven hard.

Compatibility is restricted to the named models and the finish is gun metal. The description highlights installation role and service considerations rather than performance guarantees; the part is meant for hobbyist, model-grade transmissions.

Specifications

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

Select this aluminum front gear box when you want a stronger front housing for repairs or incremental setup changes; always confirm chassis fitment and mating points before installation.

Does this replace the OEM plastic front gear box directly?

It is designed as a direct-fit replacement for the listed TAMIYA models, but verify screw patterns and mating faces on your chassis to ensure there are no fitment variances.

Will I need to adjust gear mesh after installation?

Minor gear-mesh checks and adjustments are recommended after fitting the aluminum housing to ensure gears engage smoothly and to prevent premature wear.

Are internal gears or bearings included with the housing?

The listing describes the aluminum housing; confirm with your supplier whether the package includes internal gears or bearings if those components are required.

What maintenance should follow installation?

Regularly check fastener torque, inspect gears and bearings for debris or wear, and re-evaluate gear mesh after the first few runs to ensure reliable operation.
