Quarter Midget Axle Belt Drive Sprocket 49 Tooth

The Quarter Midget Axle Belt Drive Sprocket 49 Tooth from MPD Racing is a precision-engineered component purpose-built for quarter midget racing applications where reliable power transfer and durability are non-negotiable. Quarter midgets demand exact specifications because even minor variances in sprocket geometry compromise acceleration, top speed, and overall driveline efficiency on the track. This 49-tooth sprocket serves as the primary interface between the belt drive system and the rear axle, making it essential for competitors who demand consistent performance lap after lap.

Manufactured from aluminum and finished in black anodized coating, the Quarter Midget Axle Belt Drive Sprocket 49 Tooth delivers the lightweight-to-strength ratio critical for high-RPM racing environments. The anodized finish provides corrosion resistance and durability against track exposure, vibration, and repeated thermal cycling inherent to belt drive systems. With a 2.75-inch bolt pattern, this sprocket integrates seamlessly into standard quarter midget rear-end assemblies, allowing for straightforward installation and compatibility with existing OEM frameworks—a design philosophy that MPD Racing has refined across generations of racing components.

Racers and quarter midget teams benefit most when upgrading worn sprockets or fine-tuning final-drive ratios for specific track conditions. The 49-tooth configuration balances mid-range acceleration with top-end capability, making it ideal for drivers who prioritize responsive handling and predictable power delivery over peak speed. Weighing just 0.5 pounds, this component contributes minimal rotational inertia while maintaining the rigidity required for belt tension consistency and longevity. Installation requires removal of the existing rear axle sprocket and alignment with the belt drive geometry—a straightforward procedure for any mechanic familiar with quarter midget drivetrain assembly.
