TAMIYA Hotshot/Super Hotshot/Boomerang/Bigwig Aluminum Front Gear Box by JAZRIDER JR-THS12-RD  [JR-THS12-RD]

Aluminum front gearbox for Hotshot series

This JAZRIDER JR-THS12-RD front gear box is an RC-scale replacement housing intended for TAMIYA Hotshot, Super Hotshot, Boomerang and Bigwig chassis. The unit is supplied in red and constructed from aluminum, and it is intended to serve as a durable metal alternative to the stock front gearbox housing for scale models.

Use this aluminum front gearbox when you need a straightforward swap to metal components to simplify maintenance or to consolidate front-end parts during a repair or upgrade. The part is designed to accept the same internal gears and bearings used in the original TAMIYA front gear assembly, and it acts as the structural enclosure for the front differential and related drive components on the listed models.

Installation notes: remove the original front gearbox assembly from the chassis, transfer the spur and pinion alignment and any original bearings or spacers into the JAZRIDER housing, and verify gear mesh and shaft alignment before final tightening. Keep fastener torque moderate and confirm that the gearbox rotates freely through the steering throw to avoid binding with steering or suspension components.

For builders and maintainers of the specified TAMIYA chassis who prefer metal housings for routine serviceability, this JAZRIDER aluminum front gear box provides a direct-fit option that keeps the original internal layout while changing the enclosure material and color.
