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

Precision rear gear housing for TAMIYA Hotshot vehicles

This black aluminium rear gear box is supplied as a precision aftermarket housing for the Tamiya Hotshot series models named above, replacing the original plastic rear case with a metal option aimed at workshop servicing and setup.

The aluminium housing increases rigidity around the gearset which can help preserve accurate mesh under load, supporting consistent driveline characteristics during tuning. Fitting the part requires removing the original rear housing and transferring the internal gears and bearings into the new unit, taking care to maintain correct alignments and clearances with the chassis configuration.

Opt for this aluminium rear gear box when the priority is a stable metal housing for repairs or precision setup on the listed Tamiya models; the part is intended to preserve fit and function rather than alter gear ratios.
