QM Axle Sprocket 28t

The QM Axle Sprocket 28t is a precision-engineered aluminum sprocket designed specifically for quarter midget racing applications. Built to transfer engine power efficiently to the rear axle, this 28-tooth sprocket is a critical drivetrain component for racers who demand reliable performance on competitive tracks. Quarter midgets rely on properly matched gearing to achieve optimal acceleration and top-end speed, making axle sprocket selection essential for competitive success.

Machined from lightweight aluminum in natural finish, the QM Axle Sprocket 28t delivers excellent strength-to-weight ratio without the corrosion concerns of uncoated steel alternatives. The 28-tooth configuration provides a specific gear ratio that balances acceleration and top speed—favored by many quarter midget teams for mixed-track conditions and varying track lengths. The compact dimensions and 0.3 lb weight contribute minimal rotating mass to the drivetrain, helping maintain efficiency and reduce unsprung weight that would otherwise impact handling and acceleration response.

Quarter midget racers selecting gearing for their chassis will find the 28-tooth count ideal for tracks requiring balanced mid-range power and controlled exit speeds. Direct bolt-on installation to the QM rear axle makes replacement and gearing adjustments straightforward during tuning or maintenance windows. This sprocket pairs seamlessly with standard quarter midget clutch and engine packages, making it a versatile choice for both entry-level competitors and experienced teams fine-tuning their powerplant for seasonal championships.
