Leaf springs are a type of suspension system commonly used in vehicles, especially trucks and older cars. They consist of several layers of metal strips, or "leaves," that are stacked together. This design allows the spring to flex and absorb shocks from the road, providing a smoother ride and better load-carrying capacity. The primary function of leaf springs is to support the weight of the vehicle while maintaining stability. They help to keep the tires in contact with the ground, improving traction and handling. Leaf springs are often found in conjunction with other suspension components, such as shock absorbers and control arms, to enhance overall performance.
