Car suspension refers to the system of components that connect your vehicle’s body to the wheels. Its primary purpose is to maximize tire contact with the road surface, providing stability, comfort, and control while driving. A well-functioning suspension absorbs the impact of road imperfections, ensures even weight distribution, and minimizes body roll during cornering.

How Does Car Suspension Work?

Car suspension consists of various components, including springs, shock absorbers (or struts), control arms, and stabilizer bars. Each of these parts plays an integral role in maintaining your vehicle’s stability and ride quality.

Springs

Springs are designed to absorb shocks from the road and support the weight of the car. They come in different types, such as coil springs and leaf springs, and are responsible for maintaining the proper ride height of the vehicle.

Shock Absorbers (or Struts)

Shock absorbers dampen the oscillations of the springs, preventing the car from bouncing excessively after hitting a bump. They ensure that the wheels maintain contact with the road, providing improved traction and control.

Control Arms 

Control arms connect the suspension components to the vehicle’s frame or body. They allow for controlled movement of the suspension while maintaining stability and alignment.

Stabilizer Bars 

Stabilizer bars, also known as sway bars, reduce body roll during cornering by transferring force between the left and right wheels. They enhance overall stability and control, especially in sharp turns.
