Swap in a Stronger Rear Gearbox for Your Hotshot

The JAZRIDER JR-THS13-LB aluminum rear gear box in blue is a solid upgrade for Tamiya Hotshot, Super Hotshot, Boomerang and Bigwig models. It adds a touch of colour while reinforcing the drivetrain, offering better resistance to cracking compared to stock plastic housings.

Benefits of an Aluminum Gear Case

An aluminum gear box improves rigidity and helps dissipate heat from the gear train. For drivers who push their rigs hard, the metal housing reduces deformation and keeps components aligned under load.

Fitment Notes and Installation Advice

Designed specifically for the Hotshot family, this rear gearbox fits into the original mounting points and works with standard internal gear sets. Basic tools and a careful transfer of seals and bearings make fitting straightforward.
