QM Engine Sprocket 34t

The QM Engine Sprocket 34t from TANNER is a precision-engineered aluminum sprocket designed specifically for quarter midget racing engines. This 34-tooth sprocket serves as a critical drivetrain component that transfers engine power to the transmission and final drive system. Quarter midget racers depend on reliable sprockets to maintain consistent gear ratios, optimize acceleration, and deliver predictable power delivery on tight racing circuits where every millisecond counts.

Machined from lightweight aluminum, the QM Engine Sprocket 34t reduces rotating mass while maintaining the strength required for high-RPM applications common in quarter midget powerplants. The 34-tooth configuration provides a specific gear ratio that balances acceleration and top-end speed, making it ideal for tight racing layouts where rapid direction changes demand responsive throttle response. The natural aluminum finish resists corrosion in typical racing environments, and the compact 5.6-inch outer diameter ensures compatibility with standard quarter midget engine mounting provisions without requiring extensive modification to the vehicle's drivetrain geometry.

Racers upgrading or maintaining quarter midget engines will find the QM Engine Sprocket 34t an essential wear item and performance upgrade. The lightweight construction benefits acceleration and fuel efficiency, while the precision tooth profile ensures smooth engagement with mating gears, reducing mechanical noise and transmission wear. Installation is straightforward for quarter midget platforms using standard sprocket mounting configurations; verify your engine's sprocket bore diameter and keyway dimensions before ordering to ensure proper fitment and secure retention.
