ASC21033 18T Spur Gear/Drive

This fifty-five-tooth molded spur gear and drive cup set modifies the final drive ratio for faster top-speed performance on popular miniature radio-controlled vehicle platforms. Engineered with precision-molded tooth profiles, the component ensures efficient power transmission without binding or excessive gear mesh noise. It integrates seamlessly into standard transmission topshafts and gear covers without requiring custom modifications or special adapter tools. The durable high-strength composite construction resists stripping and thermal degradation under the high-stress loads of competitive racing and modified motor systems. Included drive cups lock securely into the differential outdrives to maintain reliable rotational alignment during aggressive acceleration. Hobbyists can utilize this performance gear option to optimize straightaway velocity on open track layouts and maintain peak drivetrain durability.
