Quarter Master Ultra Duty Quick-Change Gears

These Quarter Master Ultra Duty quick-change gears have been specifically designed to run smoother and last longer than any other gears on the market. They start with the highest quality E9310 aircraft steel. The gears are precision-hobbed to AGMA Class B tolerances to produce a true involute tooth form for a high contact ratio. After a proprietary heat-treatment process, they are hand roll tested and inspected for defects. The Quarter Master Ultra Duty quick-change gears are available with a variety of different gear ratios in 10-spline versions for Sprint and late models, and 6-spline versions for Midgets.
