Precision aluminium front gearbox for vintage TAMIYA chassis

This aluminium front gear box replaces the original plastic housing used in a number of TAMIYA 1/10 off-road models. It is supplied as a direct replacement for the front gearbox positions on Hotshot, Super Hotshot, Boomerang and Bigwig chassis.

The part is machined to provide a robust support surface while allowing use of the same internal gears and bearings as the stock unit. Emphasis is on maintaining correct drivetrain geometry and reliable pinion-to-spur alignment after installation.

Fitment notes: the unit is intended for bolt-in installation with the model's original hardware. Verify gear mesh, driveshaft alignment and bearing condition as part of the fitting process. Internal components such as gears and bearings are normally reused unless the listing states otherwise.

Specifications

  • Compatibility: Hotshot, Super Hotshot, Boomerang, Bigwig

Use this aluminium front gearbox when you want a stronger metal housing for front drivetrain repairs or incremental tuning on the referenced TAMIYA models; always confirm parts included and test fitment.

Will switching to an aluminium housing change handling characteristics?

A stiffer front housing can slightly alter chassis flex and feedback, potentially making the front feel more consistent under load; changes are subtle and depend on the rest of the setup.

Does this require different gear mesh settings?

Set gear mesh as you would normally and re-check alignment after installation; the aluminium housing keeps alignment stable but initial mesh verification is still essential.

Is any additional reinforcement needed?

The machined housing itself adds rigidity; additional reinforcement is usually unnecessary unless you run extreme power or modified drivetrains.

Can I expect longer service life from aluminium?

Aluminium resists deformation better than plastic, which can help preserve alignment and extend component life when used with well-maintained internal gears and bearings.
