TAMIYA Hotshot Family Aluminum Rear Gear Housing — JR-THS13-GU by Jazrider  [JR-THS13-GU]

Heavy-duty rear gearbox shell for Hotshot series

The JR-THS13-GU rear gear box is a machined aluminum replacement designed to take the place of the original plastic shell used on TAMIYA Hotshot, Super Hotshot, Boomerang and Bigwig models. Its gun metal anodized surface and billet construction aim to improve longevity and stiffness over the stock component.

Functionally, this housing replaces the rear gearbox shell to enhance structural integrity and help keep gears aligned under load. Riders fitting upgraded motors or running in harsher conditions will notice improved resilience against impacts and wear.

Fitment tips: the part preserves the Hotshot family mounting pattern so internal parts (gears, shafts, bearings) are typically reused. Confirm gear mesh and bearing play after assembly and use the vehicle's original screws where practical; standard hex drivers cover the job.

Opt for this aluminium rear gearbox when you want a robust, direct-fit metal shell to reduce rear-end flex and lengthen service life on Hotshot-model Tamiya vehicles.
