Leaf springs are a type of suspension system used in vehicles, especially in older vehicles and trucks. They are made up of a series of curved metal plates that are stacked on top of each other and held together with a bolt or pin. Leaf springs work by flexing and absorbing shock, which helps to keep the vehicle’s tires on the ground and provides a smooth ride.
Leaf springs are relatively simple and inexpensive to manufacture, which is why they have been used for centuries. However, they are also heavy and can be prone to rust and corrosion. In recent years, leaf springs have been replaced by more modern suspension systems, such as coil springs and air springs. However, leaf springs are still used in some vehicles, especially in heavy-duty applications.
