Coil springs, shocks and struts are parts of an automobile's suspension system that both supports the vehicle and provides for a comfortable ride.

They take the guesswork out of lowering your car. Do this by turning the steering wheel back and forth and listening for binding or creaking noises.

There are, of course, exceptions, but I wouldn’t worry about replacing springs unless you have a really old vehicle. The length, thickness, number and position of the individual spring leaves affect spring rate on leaf springs. Should you always replace shocks or struts when replacing coil springs? If your wondering about replacing the struts, the struts usually need to be dis-assembled to remove the stock spring and bearing plate to be used with the new strut. However, there is a product available called a ‘quick strut’ that is a fully assembled strut complete with spring and bearing plate so you just remove the old strut assembly and put in the new ‘quick’ strut assembly.

Compared with leaf springs, coil springs are actually more durable. Generally, the coil spring is in an affordable range. A coil by definition is a mechanical device which is typically used to store energy and subsequently release it, to absorb shock, or to maintain a force between contacting surfaces. My son was doing work in Appalachian country and was driving on some pretty bad roads. Most cars spend most of their lives riding around relatively unloaded. Another popular item on the suspension market is coil-over shocks. To replace coil springs mechanics use a special spring compressor.
