QM Engine Sprocket 35t

The QM Engine Sprocket 35t is a precision aluminum pulley engineered for quarter midget racing engines where reliable power transmission and lightweight construction are non-negotiable. This 35-tooth sprocket serves as a critical drivetrain component in high-revving small-displacement engines, where every ounce of rotational mass matters. Built for competitors and enthusiasts who demand consistent performance lap after lap, the natural aluminum finish resists corrosion while maintaining the clean aesthetic expected in modern racing platforms.

Constructed from aluminum alloy, the QM Engine Sprocket 35t weighs just 0.57 lbs, minimizing rotational inertia and improving throttle response—a critical advantage in competitive quarter midget racing. The 35-tooth profile is engineered to provide optimal gear ratios when paired with compatible clutch and transmission systems, balancing low-end torque delivery with mid-range acceleration. The tight tolerances and precision machining ensure reliable mesh engagement with the chain, reducing vibration and extending drivetrain life under sustained high-RPM operation.

Quarter midget racers and engine builders rely on the QM Engine Sprocket 35t to fine-tune their powerband and maintain consistency across multiple rounds. Installation requires standard sprocket removal tools and proper chain tension adjustment; most experienced mechanics complete the swap in under 30 minutes. This component is essential for drivers optimizing their engine setup or replacing a worn sprocket as part of routine drivetrain maintenance and performance tuning.
