How to find the gear ratio of your rearend?
If you have the rearend opened up where you can see the gears, count the teeth on the ring and pinion. Divide the ring teeth number by the pinion teeth number. Example: 41 teeth on the ring and 10 teeth on the pinion = 4.10 gear ratio… Return from Gear Ratio to Drivetrain
