This black anodized aluminum rear gear box is offered as an aftermarket upgrade for the Tamiya Hotshot family models named above, replacing the stock plastic rear housing with a metal alternative. It is supplied as a finished housing intended for maintenance and setup tasks.
Beyond simple replacement, the aluminum shell adds stiffness to the rear driveline area which can limit deformation under torque and help keep gear backlash stable during tuning. Installing the unit requires the removal of the factory rear housing and careful relocation of the internal gears and bearings into the new casing, ensuring alignment and clearance are retained for proper operation.
Use this aluminum rear gear box when you want a rugged metal housing to stabilise gear mesh and support drivetrain consistency during repairs or tuning sessions on the listed Tamiya vehicles.
