TAMIYA Hotshot-Compatible Rear Gearbox Shell (Aluminum, Gun Metal) JR-THS13-GU by Jazrider  [JR-THS13-GU]

Metal rear gearbox shell tailored for Hotshot-compatible models

This JR-THS13-GU aluminium rear gearbox is produced as an aftermarket replacement for the plastic rear case used on TAMIYA Hotshot, Super Hotshot, Boomerang and Bigwig vehicles. The machined aluminium shell in gun metal aims to offer a longer-lasting, more rigid enclosure while matching the original mounting layout.

The housing's role is to replace the rear shell and improve the stability of gear alignment and rear-end structure. That stability can reduce the frequency of mesh-related wear and help the vehicle withstand rough use or more powerful drivetrains.

Assembly notes: the design keeps the original mounting points and typically reuses the car's internal gears, shafts and bearings. After installation, verify free rotation and precise gear mesh before final tightening to ensure long-term reliability.

This aluminium rear gearbox is suitable when you require a direct-fit metal housing to better protect the rear drivetrain and keep gear alignment on Hotshot-series Tamiya models.
