Aftermarket aluminium front gearbox for Hotshot lineage

This aluminium front gear box is an aftermarket metal housing intended to replace the stock plastic front casing on TAMIYA 1/10 Hotshot-era kits. It fits the Hotshot, Super Hotshot, Boomerang and Bigwig front gearbox positions as a direct replacement.

Designed to accept the original internal gears and bearings, the machined housing increases rigidity at the front gearbox mounting and helps preserve correct drivetrain alignment under load.

Installation reminder: the housing is supplied for bolt-in replacement using original fasteners. Always check gear mesh, driveshaft alignment and bearing condition when fitting. Note that internal gears and bearings are not normally included unless explicitly listed.

Suitable when you need a durable metal housing for front drivetrain repair or modest performance tuning on the referenced TAMIYA models; confirm supply contents and test fitment prior to use.

Does this housing require any chassis alterations to fit?

It is engineered to match the original mounting points and should install without chassis modification, though checking fastener lengths and clearances before final assembly is recommended.

Should I expect to buy replacement bearings with this part?

Bearings are commonly reused from the original unit; inspect them for wear and replace as needed to ensure smooth operation in the new housing.

How do I verify gear mesh after installing the aluminium housing?

Install internals loosely, rotate the drivetrain while adjusting mesh to the recommended clearance, then tighten fasteners and recheck operation for smooth engagement.

Any general precautions before driving?

Confirm all fasteners are secure, verify no binding in the drivetrain, and run a short low-speed test to ensure proper alignment before full-power operation.
