Which two types of springs are primarily associated with vehicle suspension?

The two types of springs primarily associated with vehicle suspension are leaf springs and coil springs. Leaf springs are typically used in heavier vehicles such as trucks and vans because they provide strong support and help distribute the weight of the vehicle over a larger area. They consist of multiple layers of metal, giving them the ability to handle heavy loads while also offering a degree of flexibility for cushioning the ride.

Coil springs, on the other hand, are more commonly found in lighter vehicles, including cars. They have a spiral shape that allows them to compress and expand as the vehicle moves over bumps, providing a smoother ride. Coil springs also respond more effectively to small changes in the road surface, improving the overall handling and stability of the vehicle.

While other types of springs listed do have their uses, such as in specific systems or applications, they are not the main types associated with vehicle suspension.
