The world for motorists of all types would be much more comfortable if every road was perfectly smooth. If that was how things were, there would be no need for components in a vehicle that are designed to keep that vehicle’s occupants comfortable. However, everyone knows that this is pure fantasy and that roads are not smooth. Some can be so bumpy that they will seem like obstacle courses to anyone who uses them. Fortunately, there are products available that are designed to make roads feel as though they were just paved. One such type of product is known as the coil spring.
