Upgraded aluminium front gearbox housing for classic TAMIYA buggies

This aluminium front gear box serves as a metal alternative to the stock plastic casing found on several TAMIYA 1/10 off-road kits. It is presented as a direct-fit replacement for the Hotshot, Super Hotshot, Boomerang and Bigwig front assembly.

The part delivers a machined mounting surface intended to maintain the original internal gear and bearing arrangement while increasing structural stiffness at the front gearbox location. It is engineered to keep pinion and spur alignment correct when installed on the stated chassis.

Installation guidance: the component is made for bolt-in replacement using the existing fasteners and layout. Always verify gear mesh, driveshaft alignment and the condition of bearings during assembly. Internal gears and bearings are generally not supplied unless clearly stated by the seller.

  • Compatibility: Hotshot, Super Hotshot, Boomerang, Bigwig

Ideal when you require a durable metal replacement for front drivetrain maintenance or modest tuning on the listed TAMIYA chassis; confirm what is included and check fit before you buy.

The machined aluminium housing increases structural rigidity and resists deformation under load better than the stock plastic, which can improve long-term alignment of drivetrain parts.
Metal housings can change resonance and transfer vibration differently than plastic; correct gear mesh and bearing condition will minimize noise and wear.
It is designed as a direct-fit using original mounting points, but confirm fastener lengths and clearances to avoid interference.
Inspect bearings during installation; if they show play or wear, replace them to protect gear life and alignment in the new housing.
