The vehicle’s springs are the foundation of the suspension system. Their job is to hold the weight of the vehicle and its passengers, keep the car high enough so it doesn’t bottom out, and allow the wheels to move up and down without jolting your passengers. In this blog, we’re going to discuss a few different types of springs found on modern cars and trucks!

Steel Coil Spring 

The steel coil spring is the most common type of spring, and can be seen on most cars on the road. Essentially, this coil spring is a heavy-duty steel bar wound into a coil. It compresses and expands to absorb the impact of roads. So while you drive, the bumps you run over are less noticeable!

Leaf Spring

Seen on many trucks and even some sports cars, such as the Chevrolet Corvette, a leaf spring  consists of several “leaves” clamped together to form one unit. Each leaf is a thin, flat, arc-shaped piece of metal, and they’re stacked on top of each other. The more leaves, the more weight the vehicle can carry. Pretty neat, right?

Air Spring

An air spring can be described as a cylinder filled with air and positioned between the control arm and car’s body. A compressor fills the cylinder, which is typically made of a high-quality rubber and holds the vehicle up. The air then absorbs energy transferred to the wheels and tires from the road. You can find these types of springs on luxury cars!

Hydraulic Spring

These springs are also common on higher-end vehicles and use hydraulic fluid pressurized by a pump. The fluid acts as the cushion between you and road. In most cars, the height of the vehicle is constantly adjusted by computers and sensors, for a smoother ride while on the road.
