What is the gear ratio of the Ford f450?

The gear ratio of the Ford F450 is 4.10:1. This means that for every single rotation of the driveshaft, the rear wheels will rotate 4.10 times. The gear ratio is an important specification that determines the truck's towing capacity, acceleration, and fuel efficiency.

Understanding Gear Ratios

The gear ratio is a measure of the relationship between the rotational speed of the engine and the rotational speed of the wheels. It is expressed as a ratio, such as 4.10:1. This ratio indicates that for every single rotation of the driveshaft, the rear wheels will rotate 4.10 times.

A higher gear ratio, such as 4.10:1, results in more torque being delivered to the wheels, which is beneficial for towing heavy loads or climbing steep hills. However, a higher gear ratio also means the engine will be spinning faster at a given vehicle speed, resulting in lower fuel efficiency.

The Ford F450's Gear Ratio

The Ford F450 is a heavy-duty pickup truck designed for towing and hauling large loads. Its gear ratio of 4.10:1 is well-suited for this purpose, as it provides ample torque to the rear wheels.

• The 4.10:1 gear ratio is available on the F450 with the 6.7L Power Stroke diesel engine.


• This gear ratio is optimized to deliver maximum towing capacity, which for the F450 is up to 37,000 pounds when properly equipped.


• The high gear ratio also contributes to the F450's impressive payload capacity of up to 7,850 pounds.

While the 4.10:1 gear ratio provides excellent towing and hauling capabilities, it does result in slightly lower fuel efficiency compared to lower gear ratios. Drivers who prioritize fuel economy over maximum towing capacity may opt for a different gear ratio configuration on their F450.

What is the rear axle rating of the Ford F450?

The F-250 tops out with a 6,340-pound maximum rear gross axle weight rating (GAWR), the F-450 tops out with a 10,300-pound GAWR, and the F-450 with a 9,900-pound GAWR on the rear axle. Dual Rear Wheels — The F-450 is built with standard dual rear wheels, while the F-250 is only built with single rear wheels.

Which is better, 3.73 or 4.10 axle ratio?

Neither 3.73 nor 4.10 gears are inherently "better"; the choice depends on your driving priorities. 4.10 gears provide quicker acceleration and more torque, which is ideal for performance or heavy towing, but at the cost of lower fuel economy and higher engine RPMs at highway speeds. 3.73 gears offer better fuel economy and a higher top speed because the engine runs at a lower RPM on the highway, making them better for general cruising and long-distance driving.

4.10 gears

• Pros:
  • Quicker acceleration and a faster feel off the line. 
  • More torque, making them better for towing heavy loads. 
• Cons:
  • Lower fuel economy. 
  • Higher engine RPMs at highway speeds, which can lead to more engine noise. 

3.73 gears 

• Pros:
  • Better fuel economy. 
  • Higher top speed because the engine runs at lower RPMs on the highway. 
  • Quieter and more comfortable for highway cruising. 
• Cons:
  • Slower acceleration compared to 4.10 gears. 
  • Less torque for towing.

How to choose

• Choose 4.10s if: Your priority is performance, and you want a vehicle that feels quick off the line. They are also a good choice if you frequently tow heavy loads. 
• Choose 3.73s if: Your priority is fuel economy and comfortable, quiet highway cruising. They are a better all-around choice for a daily driver or a vehicle that spends most of its time on the open road. 

What is the gear ratio for the 2017 Ford F450?

The standard gear ratio for a 2017 F-450 is 4.30, especially with the Max Tow package. While some aftermarket options or specific configurations might exist (such as a 4.88 ratio), the 4.30 ratio was the factory standard for this model year and was specifically designed for its towing capabilities.

• Standard ratio: 4.30 
• Purpose: This ratio is optimized for towing, as it provides better leverage for pulling heavy loads. 
• Alternative ratios: Although 4.30 is standard, other ratios like 4.88 were available through aftermarket upgrades or specific configurations.
