TAMIYA Hotshot / Super Hotshot / Boomerang / Bigwig Rear Gear Box by JAZRIDER JR-THS13-BK  [JR-THS13-BK]

Rear gear box for TAMIYA Hotshot series

This aluminum rear gear box is a direct product option for use on Tamiya Hotshot family models named above, supplied in black finish. It replaces the rear gear housing to provide a metal alternative to the original plastic housing, aimed at hobby-scale maintenance and setup work.

The component's role is primarily structural and tuning-oriented: a stiffer housing helps maintain gear mesh under load and can reduce deformation that affects backlash and driveline consistency. Installation requires removing the original rear housing and transferring internal gears and bearings into the new unit, keeping alignment and clearances consistent with the chassis setup.

Choose this aluminum rear gear box when you need a stable, metal housing for repair or setup work on the listed Tamiya models; it focuses on fit and structural consistency rather than altering gear ratios or internal components.
