When track conditions change and you need to pick a new gear in a hurry, Quarter Master has you covered. Over sixty years of gear manufacturing know-how went into the development of the Quarter Master Ultra-Duty Quick Change Gears, all with the end goal of producing on-track results that can’t be beat. Made from the highest quality E9310 aircraft steel, these gears are precision hobbed to AGMA Class B Tolerances, thereby producing a true involute tooth form for a high contact ratio. They are finished with a proprietary heat-treatment process for long lasting durability and are then hand roll tested and inspected. Designed for high horsepower applications, Quarter Master Ultra-Duty Quick Change Gears are available with 64 gear ratios in 10-Spline for Sprint Cars and Late Models and 42 gear ratios in 6-Spline for Midget race cars.
