Here is a used set of Quarter Master Ultra duty 10 spline quick change gears. They are set # 7A. 21/24 tooth count. They are 4.71 ratio with a 4.11 ring and pinion and 5.55 ratio with a 4.86 ring and pinion. I used these in a vintage dirt race car and they worked good, no issues. No chips or major damage on the teeth, good used condition. Any questions please ask.
This product would be ideal for high-performance race car enthusiasts and skilled mechanics looking to upgrade their race car's engine and transmission components with a reliable, high-quality drivetrain that offers precise gear ratios for optimal performance.
