Shocks, or shock absorbers are the part of your vehicle responsible for maintaining a comfortable ride. They perform one of two functions. Firstly, they are designed to absorb any vibrations, jolts or bounces you experience while driving your vehicle.
In their simplest form, shock absorbers are hydraulic (oil) pump like devices that help to control the impact and rebound movement of your vehicle's springs and suspension. Along with smoothening out bumps and vibrations, the key role of the shock absorber is to ensure that the vehicle's tyres remain in contact with the road surface at all times, which ensures the safest control and braking response from your car.
