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

Aftermarket rear gear housing for TAMIYA Hotshot models

This black aluminum rear gear box is a direct replacement housing intended for the Tamiya Hotshot range listed above. The part provides a metal alternative to the original plastic shell and is aimed at repair, maintenance and setup work by hobbyists.

The primary benefit is additional structural support around the rear gear train, reducing flex and assisting consistent gear alignment under load. Installation involves removing the original housing and carefully refitting the existing gears and bearings into the aluminium casing, observing the same alignment and clearance practices used with the stock part.

This aluminium rear gear box is suited for those seeking a firmer housing for routine repairs or setup work on the specified Tamiya models, focusing on structural consistency without altering gear internals.
