How to Identify Your Axle Ratio
For the 2021 Toyota Highlander, the easiest way to identify your axle ratio is by looking at the sticker on the driver-side door jamb. This sticker contains a wealth of information about your vehicle, including the axle code. The axle code is typically a four-digit code beginning with "A" and ending in "A". You can also use a VIN decoder to find your vehicle's axle ratio.
Towing vs. MPG Impact
A numerically lower axle ratio (such as 2.56:1) will result in better fuel economy, as the engine will be turning at a lower RPM at any given speed. A numerically higher axle ratio (such as 3.003:1) will result in better towing performance, as the engine will have more torque available to the wheels.
