Does Ford still use twin I-beam?
The twin I-beam suspension system is a unique engineering design that has been a hallmark of Ford's vehicle lineup, particularly in their trucks. This article explores whether Ford continues to utilize this suspension system in their current models and the implications of its design.
What is Twin I-Beam Suspension?
Twin I-beam suspension is a type of independent front suspension that was first introduced by Ford in the 1960s. It features two separate beams that allow each wheel to move independently, providing better handling and ride quality compared to traditional solid axles. This design has been particularly popular in Ford's F-Series trucks.
Current Use of Twin I-Beam Suspension
As of 2025, Ford has phased out the twin I-beam suspension in most of its newer models. The last significant use of this system was in the Ford F-150, which transitioned to a more modern independent front suspension setup in recent generations. This change was made to enhance performance, fuel efficiency, and ride comfort.
Reasons for the Transition
- Improved Handling: Modern independent suspensions provide better handling characteristics, especially in off-road conditions.
- Enhanced Comfort: Newer designs offer a smoother ride by better absorbing road imperfections.
- Weight Reduction: Advances in materials and design have allowed for lighter suspension systems, improving fuel efficiency.
- Technological Advancements: New suspension technologies, such as adaptive dampers, are not compatible with the twin I-beam design.
Conclusion
While the twin I-beam suspension was a revolutionary design for its time, Ford has moved towards more advanced suspension systems in its current vehicle lineup. This shift reflects the automotive industry's ongoing evolution towards improved performance, comfort, and efficiency. For those who appreciate the classic twin I-beam design, it remains a nostalgic feature of older Ford trucks, but it is no longer a part of Ford's modern engineering strategy.

Why did Ford stop using twin I-beam?
Ford had noted the arguments against A-arm suspension—durability and tire wear, among them—in a 1965 SAE paper suitably titled, “Twin-I-Beam: A Unique Truck Independent Front Suspension.” Ford engineers recognized the advantages of what they referred to as short/long-arm suspension—stable geometry with suspension ...
How long did Ford use the twin I-beam suspension?
Introduced in 1965, Twin I-Beam was used on all 2WD models until 1984 when the F-100 was discontinued. Phased out after 1996; replaced by independent front suspension (IFS) starting in 1997. Used in 2WD models; 4WD models used Twin Traction Beam (TTB) from 1980 onwards, phased out in 2016.
What type of suspension does a F-150 have?
Honestly. From the 1930s for decades for decades this has been in trucks. This design has been in cars since the beginning of cars. It's called a Hotchkiss design.
What was the last year Ford used twin I beam suspension?
Twin I-Beams and Twin Traction Beams were utilized on various F-Series trucks until 2002. Each heavy-duty coil spring can compress and expand on its own, without disturbing the opposite wheel. Depending upon gross vehicle weight rating, the system could use either coil or leaf springs.
What is the most popular used suspension in today's vehicles?
independent multi-link suspension
Also referred to as a multi-link rear suspension or independent multi-link suspension, the multi-link suspension is commonly used in modern vehicles, particularly high-performance cars and luxury vehicles.
What year did Ford go to independent front suspension?
1980
Ford Motor Co.'s new twin traction beam suspension for its 1980 four-wheel drive vehicles uses stamped support arms and a third U-joint in the front axle to achieve independent front suspension (IFS). The new suspension was specially developed for the front drive axle.
Why do Ford's still have antennas?
Truck drivers, Ford has found, are different. In talking to Mike Levine, Ford's Product Communications Manager, he summed up why Ford still uses the old whips like this: The mast antenna supports the AM/FM performance best over other design options.
What is the smoothest suspension system?
Air suspension utilizes air springs instead of traditional coil or leaf springs. It allows for adjustable ride height and stiffness, providing a customizable and smooth ride.
