TAMIYA Hotshot/Super Hotshot/Boomerang/Bigwig Front Gearbox Aluminum Replacement - JR-THS12-RD by Jazrider  [JR-THS12-RD]

Aluminum front gearbox for Hotshot lineup

This Jazrider JR-THS12-RD front gear box is an RC-scale replacement housing made for TAMIYA Hotshot, Super Hotshot, Boomerang and Bigwig chassis. The unit comes in red and is machined from aluminum to provide a long-lasting metal alternative to the stock front gearbox housing.

Fit this aluminum front gearbox when you want a direct metal swap to simplify maintenance or consolidate front-end components during a repair or upgrade. The housing is engineered to accept the same internal gears and bearings as the original TAMIYA front gear assembly and serves as the structural enclosure for the front differential and related drive parts on the listed models.

Installation notes: remove the original front gearbox from the chassis, transfer spur and pinion alignment plus any original bearings or spacers into the Jazrider housing, and confirm gear mesh and shaft alignment prior to final tightening. Use moderate fastener torque and verify the gearbox rotates freely through the steering throw to avoid binding with steering or suspension parts.

For builders and maintainers of the specified TAMIYA chassis who prefer a metal housing for easier servicing, this Jazrider aluminum front gear box provides a direct-fit option that preserves the original internal layout while changing the enclosure material and color.
