Here is a used set of WINTERS 10 spline quick change gears. They are set # 3. 25/31 tooth. They are 5.11 ratio with a 4.11 ring and pinion and 6.02 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
