Suspension is a system of components that work together to connect a vehicle’s body to its wheels, manage vertical movement of the wheels and tires, and provide maximum contact and traction with the road surface. The suspension system comprises multiple parts, including springs, struts, shocks, control arms, sway bars, ball joints, and tires.

The springs are the primary component of the suspension system and play a vital role in supporting the weight of the vehicle while absorbing and dampening road shocks. The most common types of springs used in vehicles are coil springs and leaf springs.

Struts and shocks work together to control the vertical movement of the suspension system, keeping the wheels in contact with the road surface. Struts are a self-contained unit that includes the spring and shock absorber, while shocks are separate from the springs and designed to dampen the springs’ oscillations.

Control arms help to transfer the vehicle’s weight from the wheels and tires to the suspension components. They are also critical in controlling the wheels’ movement and keeping them aligned to provide optimal handling and stability.

Sway bars connect the vehicle’s body to its suspension components, reducing body roll and enhancing stability during cornering or sudden maneuvers.

Ball joints connect the suspension components to the steering components, allowing for smooth and precise movements during turns or changes in direction.

Finally, the tires are an integral component of the suspension system, responsible for providing grip, traction, and stability as the vehicle travels over various surfaces.

In summary, the suspension system is critical to maintaining vehicle control, ride comfort, and safety during driving. A well-maintained suspension system is crucial for optimal vehicle performance and longevity.
