JAZRIDER JR-THS13-LB blue aluminium rear gearbox for Tamiya Hotshot / Super Hotshot / Boomerang / Bigwig - precision upgrade  [JR-THS13-LB]

Durable Aluminium Rear Gearbox for Tamiya Hotshot Cars

The JAZRIDER JR-THS13-LB blue aluminium rear gear box gives Tamiya Hotshot, Super Hotshot, Boomerang and Bigwig models a tougher rear end. The metal case reduces the risk of cracking and keeps internal parts better supported than the original plastic housing.

Practical Benefits of a Metal Case

With increased rigidity and improved thermal conductivity, an aluminium gear box helps maintain gear alignment under stress and dissipates heat from prolonged runs, which can extend component life.

Fitment and Installation Notes

Built to match Hotshot-series mounting points, this gearbox is a direct replacement. When installing, transfer bearings and seals carefully and verify screw lengths to ensure a secure fit without contact to moving parts.
