Next to the engine and speed, the suspension system is important when it comes to cars. The suspension system serves two purposes. First, they contribute to the car's handling and braking for safety. Second is they keep passengers comfortable from bumps and other vibrations. A vehicle's suspension system is composed of different parts. One of them is the springs.

For the Swedish automaker, Volvo, safety and quality are key factors in manufacturing automobiles. For some of their vehicles, the company uses Volvo coil springs. It is actually the most common type of spring. They are also known as a helical spring because they are formed into the shape of a helix or spiral. Volvo coil springs are usually made of elastic materials that compress and expand to absorb the motion of the wheels.

There are actually two types of coil springs. There are tension coil springs which are designed to resist stretching. They usually have a hook or eye form at each end for attachment. There are also compression coil springs designed to resist being compressed.

The production of coils springs are not easy. Many of them are first wound in an annealed condition and then tempered to achieve some strength. After some time, this tempering can be lost and the spring will sag because it can no longer withstand the loads applied. But they can be re-set by returning them to their original length or setting them to a different length. Cutting the end of a car suspension spring to lower its height can cause some damage to the suspension system making it work inefficiently.

The suspension system is vital to any vehicle. The presence of Volvo Coil Springs also make the system work more effectively. A fast car without a good suspension will be very uncomfortable, not to mention the potential hazards it creates for the passengers.
