How to identify your axle ratio
The easiest way to identify your axle ratio is to use a VIN decoder. You can also check for a metal tag on the differential housing. The tag will have the ratio stamped on it (e.g., 3.45).
Towing vs MPG impact
A numerically lower axle ratio (e.g., 3.09) will result in better fuel economy, while a numerically higher axle ratio (e.g., 3.70) will provide better towing performance.
