What is an Axle Ratio?
The axle ratio, also known as the final drive ratio, refers to the number of times the driveshaft rotates compared to the number of times the wheels rotate. This ratio determines the amount of torque and speed delivered to the wheels. A higher axle ratio, such as 4.10:1, provides more torque for towing and hauling, while a lower ratio, like 3.73:1, prioritizes fuel efficiency and highway driving. The axle ratio is an important specification to know when modifying your F250 or choosing the right gear for your needs.

Will my VIN number tell me my gear ratio?
You don't. That information is not contained in the VIN, UNLESS a specific model only gets one rear end ratio. VIN tells country of manufacture, vehicle make, class, engine type, size, date of manufacture, plant and serial number. That is the ONLY information contained by the VIN.

Which is better, 3.73 or 4.10 axle ratio?
ARE 3.73 OR 4.10 GEARS BETTER? Use this rule of thumb: The shorter the gear ratio (higher number), the easier it will be for the vehicle to start moving and accelerating! This will, however, lower the top speed of the vehicle.
