What is the rear gear ratio of the 2017 Ford F450?
The rear gear ratio of the 2017 Ford F450 is 4.30:1. This means that for every 4.30 revolutions of the rear axle, the driveline will make one complete revolution. The rear gear ratio is an important specification that affects the truck's towing capacity, fuel efficiency, and overall performance.
Understanding Rear Gear Ratio
The rear gear ratio is a critical component of a vehicle's drivetrain. It determines the relationship between the rotation of the rear wheels and the rotation of the driveline, which includes the transmission, driveshaft, and differential. A higher rear gear ratio, such as 4.30:1, results in more torque being delivered to the wheels, which is beneficial for towing and hauling heavy loads. However, it also leads to lower fuel efficiency at highway speeds.
Manufacturers like Ford offer a range of rear gear ratio options for their trucks to cater to different customer needs. The 2017 Ford F450 is available with the following rear gear ratio choices:
- 3.73:1
- 4.10:1
- 4.30:1 (as found in the example)
- 4.88:1
The 4.30:1 rear gear ratio is a popular choice for the F450, as it provides a good balance between towing capacity and fuel efficiency for many users.
Factors Affecting Rear Gear Ratio Selection
When choosing the appropriate rear gear ratio for a truck like the 2017 Ford F450, several factors are considered:
- Towing and Hauling Needs: Heavier loads and trailers require a higher rear gear ratio for more torque and pulling power.
- Fuel Efficiency: Lower rear gear ratios, such as 3.73:1, are more fuel-efficient at highway speeds, but may sacrifice towing capacity.
- Engine and Transmission Specifications: The engine's horsepower and torque, as well as the transmission's gear ratios, influence the optimal rear gear ratio selection.
- Driving Conditions: Vehicles used primarily for off-road or heavy-duty applications may benefit from higher rear gear ratios, while those driven mostly on highways may perform better with lower ratios.
By carefully considering these factors, Ford engineers determine the rear gear ratio options that best meet the needs of F450 customers.
What is the gear ratio for the rear end of the F-450?
2017 2018 2019 2020 2021 2022 Ford F-450 F-550 Super Duty Rear Differential Axle Gear Ratio 4.88.
What is the rear axle rating of the F-450?
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.
How do I find my Ford axle ratio?
To determine the axle ratio of your vehicle, locate the two-digit axle code first, then use your vehicle's towing guide to find the axle ratio that corresponds to that code. If your vehicle has a limited-slip differential, it will be noted as Limited Slip.
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.
What is the rear gear ratio of a 2017 F-350?
YesI know it has a 3:55 ratio rear-end ....
Why are 3.73 gears good?
In a sports car, 3.73 gears will offer better acceleration while retaining top speed when compared to 3.55 gears that come factory on many sports cars.
What is the axle ratio for the 6.7 PowerStroke?
Consider a PowerStroke 6.7-liter diesel that offers a choice of a 3.31, 3.55, 3.73 or 4.30 axle ratio. The 3.31 might be capable of towing the trailer. But if you are towing the majority of the time, you probably want the 3.55 because it will tow better and provide better fuel economy loaded.
What is the gear ratio for the 2017 f450?
Aside from a standard 4.30:1 axle ratio (4.10 gears are the optional upgrade on the F-350), the F-450 gets larger-diameter disc brakes at all four corners, 10-bolt wheels (versus 8-bolt units), and a wider front track.
What is my rear axle ratio?
Method 1: Count the number of teeth on the ring gear and the pinion. Divide the number of the ring gear's teeth by the number of the pinion's teeth. This will give you the axle ratio.
What axle does a F-450 have?
Starting with the 2005 model year, the Dana S-110 is used in all F-450 cab and chassis trucks. F-550 trucks started using the S-110 axle effective with the 2005 model year instead of the oversized for the application, Dana S-135 that equipped 1999-2004 era 1-1/2 ton F-550 models.
