What is a defining characteristic of leaf springs?

Leaf springs are primarily characterized by their construction, which consists of layers of metal plates, or leaves, that are stacked and curved. This design allows for flexibility and strength, enabling the leaf spring to support heavy loads while maintaining the vehicle's stability. The layers work together to distribute the load across the spring, providing a resilient support system.

In addition, leaf springs have a simple and effective design that has been widely used in both rear and front suspension systems, particularly in trucks and larger vehicles, where heavy-duty support is necessary. Their layered structure also plays a significant role in the suspension's ability to absorb shocks and enhance ride quality, making them a key component in many automotive applications.

This characteristic differentiates leaf springs from other types of springs, such as coil springs, which are made from coiled metal and have a different operational mechanism. The purpose and versatility of leaf springs are also reflected in their potential for achieving a level of ride height adjustment, but this isn't a defining characteristic—it is a supplementary benefit based on their design and mounting methods.
