What size are the rear axles on a Ford Transit?
The Ford Transit is a popular choice for both commercial and personal use, known for its versatility and reliability. One of the most critical components of this vehicle is its rear axle, which plays a vital role in supporting the vehicle's weight and ensuring smooth operation. If you're looking to understand the size of the rear axles on a Ford Transit, this guide will provide you with the details you need.
Understanding Rear Axle Sizes
The size of the rear axle on a Ford Transit can vary depending on the model year, configuration, and specific trim level. Generally, the rear axle size is determined by the axle ratio and the type of drivetrain (rear-wheel drive or all-wheel drive). Here are some key points to consider:
- Ford Transit 150, 250, and 350 models typically feature rear axles with a diameter of approximately 3.5 inches for standard configurations.
- Heavy-duty versions of the Transit, such as the Transit 350HD, may have larger rear axles to accommodate increased payload and towing capacities.
- The axle ratio, which affects performance and fuel efficiency, is another important specification. Common ratios for Ford Transits include 3.31, 3.73, and 4.10, depending on the intended use of the vehicle.
Why Rear Axle Size Matters
The size of the rear axle is crucial for several reasons:
- Load Capacity: Larger axles are designed to handle heavier loads, making them ideal for commercial applications.
- Durability: A properly sized axle ensures the longevity of the drivetrain and reduces wear and tear.
- Performance: The axle size and ratio directly impact the vehicle's acceleration, towing capacity, and fuel efficiency.

Frequently Asked Questions
How do I know what size rear axle I have?
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.
How do I identify my Ford rear axle?
The ID tag can be your friend. It will tell you the gear ratio, rearend style, and whether it has limited-slip. Also on the tag is an ID number, which, until 1985, included four to five letters, no numbers. Almost all 8.8s—and all post-1986 Ford rearends—have letters and numbers.
