A car suspension is a system of springs, dampers, control arms, and linkages that connect the wheels to the body.
The suspension plays the lead role in optimizing a car’s ride comfort and handling. The function of the car suspension is to ensure that bumps, jerks, and road imperfections are controlled and absorbed so that they don’t make the ride uncomfortable or weight transfers dangerous. Without the suspension, a smooth, controlled ride would be virtually impossible.
The earliest automobiles made use of dependent suspensions on all wheels. As technology improved, car engineers came up with semi-dependent and independent suspensions.
A family car often uses a compliant suspension for a plusher ride for the passengers. Sports cars, however, have stiffer suspensions that help ensure tighter control and better handling.
If your ride quality becomes increasingly harsh when driving over uneven surfaces, parts of the suspension may need repair or replacement. You can use the Kelley Blue Book Service Advisor tool to find maintenance providers, pricing, and estimates specific to the make and model of your car.
