What vehicles have leaf springs?
Leaf springs are a type of suspension system commonly used in various vehicles, particularly trucks, SUVs, and some older car models. Leaf springs are made up of a series of flat, curved metal leaves that are stacked and secured together, allowing the vehicle to absorb shocks and provide a smooth ride.
What are Leaf Springs?
Leaf springs are a type of suspension system that uses a series of flat, curved metal leaves that are stacked and secured together. The leaves are typically made of steel and are designed to flex and absorb the impact of bumps and uneven terrain. Leaf springs are commonly used in the rear suspension of trucks, SUVs, and some older car models.
Vehicles with Leaf Springs
Leaf springs are found in a variety of vehicles, including:
- Trucks: Leaf springs are a common suspension system in pickup trucks, such as the Ford F-150, Chevrolet Silverado, and Ram 1500. They provide a sturdy and durable suspension that can handle heavy loads and towing.
- SUVs: Many SUVs, such as the Jeep Wrangler, Toyota 4Runner, and Ford Expedition, use leaf springs in their rear suspension.
- Older Cars: Some older car models, particularly those from the 1950s to the 1970s, were equipped with leaf spring suspension, such as the Chevrolet Bel Air and Ford Mustang.
Leaf springs offer several advantages, including their simplicity, durability, and ability to handle heavy loads. However, they can also provide a rougher ride compared to more modern suspension systems, such as coil springs or air suspension.
Advantages of Leaf Springs
Leaf springs offer several advantages that make them a popular choice for certain types of vehicles:
- Durability: Leaf springs are known for their ruggedness and ability to withstand heavy loads and harsh conditions. They are less prone to wear and tear compared to other suspension systems.
- Load-Bearing Capacity: Leaf springs are well-suited for vehicles that need to carry heavy loads, such as trucks and SUVs. They can support a significant amount of weight without compromising the ride quality.
- Simplicity: Leaf spring suspension systems are relatively simple in design, making them easier to maintain and repair compared to more complex suspension systems.
While leaf springs offer these advantages, they can also provide a rougher ride compared to more modern suspension systems. As a result, many newer vehicles are moving towards alternative suspension designs, such as coil springs or air suspension, which can offer a smoother and more comfortable ride.
What are the cons of leaf springs?
The ride comfort isn't as great because of the inter-leaf friction between each leaf. Over time, the springs tend to lose shape and can sag. When the sag is uneven, it can alter the cross weight of the vehicle which can affect the handling slightly. This can also change the axle-to-mount angle.
When did they stop using leaf springs?
Leaf springs were very common on automobiles until the 1970s when automobile manufacturers shifted primarily to front-wheel drive, and more sophisticated suspension designs were developed using coil springs instead.
Did Mustangs have leaf springs?
The '65-'73 Mustangs used a combination of front coil springs and rear leaf springs. Eaton Detroit Spring is one of the few companies that manufacture both, either by following factory blueprints or custom.

Do new cars use leaf springs?
While car manufacturers have mostly replaced leaf springs with coil springs in their newer models, many vehicles still have the older suspension system. You can also replace the existing coil spring suspension with its leaf counterpart.
Which is better, leaf spring or coil spring?
Coil spring suspensions provide more range of suspension movement and allow the user a wider turning envelop through the suspension range than the leaf springs. Practically all high-performance applications use coil springs where possible if the budget permits.

How long do leaf springs usually last?
If not exposed to road salt or overloaded, leaf springs can last the lifetime of your vehicle. However, you can expect their lifespan to diminish if frequently abused or driven across salty roadways. On the other hand, rubber bushings typically last 10-15 years if the vehicle is maintained correctly.
Does every truck have leaf springs?
Trucks that commonly use leaf springs are light commercial vehicles (LCVs) and heavy goods vehicles (HGVs). Many other vehicles use spring absorber suspension systems but leaf style springs are becoming a much more common and popular option.
