What is Axle Ratio?

The axle ratio is a numerical value that represents the ratio between the number of teeth on the ring gear and the number of teeth on the pinion gear in a vehicle's differential. It affects the vehicle's performance, including acceleration, fuel efficiency, and towing capacity.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ AR = \frac{40}{10} = 4.00 \]

The axle ratio is 4.00.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ AR = \frac{35}{9} = 3.89 \]

The axle ratio is 3.89.
