If you’re like most of us, you want your car to handle well. That’s the job of your suspension system.
There are different types of suspension systems, but they all work
on the same basic principles. First, there are the springs, which bear
the weight of the car. The most common springs are coil or leaf –
although we see air springs and torsion bars more often. The springs do
most of the work.
But if all you had were springs, your vehicle would be bouncing
around like a bobble head. That’s where the shocks come in. They
control the rebound of the springs and smooth out the up and down
motions. They also keep the tires on the road, and you in control. Some
cars use struts. Struts are a combination of shocks and springs,
together in a more compact system.
