QM Axle Sprocket 31t

The QM Axle Sprocket 31t is a precision-engineered aluminum pulley designed specifically for quarter midget racing applications where reliable power transmission and consistent performance are non-negotiable. This 31-tooth sprocket serves as a critical drivetrain component, transferring engine power to the rear axle while maintaining the tight tolerances required in competitive quarter midget racing. Whether you're building a new quarter midget or upgrading an existing drivetrain, this axle sprocket delivers the durability and precision that racers depend on for consistent lap times and reliable performance on the track.

Manufactured from aluminum and finished in natural anodize, the QM Axle Sprocket 31t combines lightweight construction with corrosion resistance and longevity in demanding racing environments. The 31-tooth configuration is optimized for quarter midget gearing ratios, providing the balance between acceleration and top-end speed that competitive drivers require. At just 0.36 lbs, the minimal weight reduces unsprung mass on the rear axle assembly, contributing to improved handling and responsiveness. The compact dimensions (2.6 x 0.55 x 5.3 inches) ensure proper fitment within standard quarter midget rear-end housings without interference or clearance issues.

Quarter midget racers, from weekend hobbyists to serious competitors, benefit from upgrading to OEM-specification sprockets like this TANNER component when replacing worn gearing or optimizing drivetrain setup. Installation is straightforward for anyone familiar with quarter midget rear-axle service—the sprocket mounts directly to the axle in place of worn originals. This individual unit (sold as each) allows selective replacement of damaged teeth or gearing upgrades without requiring a complete rear-end overhaul, making it an economical maintenance and performance solution for quarter midget platforms.
