How wide are the axles on a Ford 9?
The Ford 9-inch rear axle is one of the most popular and versatile rear-end assemblies in automotive history. Known for its strength, durability, and adaptability, it has been a favorite among hot rodders, off-road enthusiasts, and drag racers for decades. If you're considering using a Ford 9-inch axle for your project, understanding its dimensions is crucial for proper fitment and performance.
Standard Widths of Ford 9-Inch Axles
The width of a Ford 9-inch axle can vary depending on the vehicle it was originally designed for. Here are some of the most common factory axle widths:
- 57.25 inches: Found on early Ford passenger cars, such as the 1957-1959 Ford Fairlane and Ranchero.
- 58 inches: Commonly used in early Ford Mustangs and Falcons.
- 61 inches: Found on full-size Ford cars and trucks, such as the F-100 pickup trucks.

These measurements refer to the overall width of the axle housing, measured from flange to flange. The actual width of the axle assembly, including the brake components, may vary slightly.
Customizing the Width for Your Project
One of the reasons the Ford 9-inch is so popular is its adaptability. Many aftermarket companies offer custom-width housings and axles to fit specific applications. Whether you're building a street rod, a race car, or an off-road vehicle, you can have the axle narrowed or widened to suit your needs.
When customizing the width, consider the following:
- Wheel and Tire Fitment: Ensure the axle width allows for proper clearance between the tires and the body or suspension components.
- Suspension Geometry: The axle width can affect the suspension's performance and handling characteristics.
- Drivetrain Alignment: Proper alignment of the driveshaft and differential is essential for smooth operation.
