What does a shock absorber do?
Essentially, shock absorbers do two things. Apart from controlling the movement of springs and suspension,
shock absorbers also keep your tyres in contact with the ground at all times. At rest or in motion, the bottom
surface of your tyres is the only part of your vehicle in contact with the road.
