TAMIYA Hotshot Aluminum Rear Gearbox Upgrade for Hotshot/Super Hotshot - JR-THS13-RD by Jazrider  [JR-THS13-RD]

Rear housing to reduce drivetrain flex on Hotshot chassis

This aluminum rear gear box serves as an aftermarket hop-up tailored for TAMIYA Hotshot series models. Finished in red anodized aluminum, it replaces the original plastic case to cut down flex and provide a more positive mounting platform for rear drivetrain components. It is intended for hobbyists who want enhanced dimensional stability without altering gear ratios.

The unit retains the original pattern of fasteners and locating points so it accepts the stock spur and pinion layout. Check for interference if you use low-profile suspension parts or non-standard motor mounts, and verify output shaft alignment prior to final torqueing. For standard configurations no trimming should be required.

As a tuning upgrade this part helps maintain rear geometry under load, which can reduce lash and yield steadier throttle feel during hard driving or jumps. Remember this is an RC upgrade for model use only.
