Shock absorbers or shocks were built to help absorb the up-and-down shock created by the springs whenever a vehicle hits a bump. Aside from absorbing the impact, they also keep the car or truck easily maneuverable even after a bumpy ride. The absence of shock absorbers would definitely result to a bouncing ride as energy is stored in the spring and then released to the vehicle, oftentimes exceeding the permitted range of suspension movement.
Today's technologically-advanced shock absorbers are fitted with velocity hydraulic damping devices which provide increased speed in the movement of the suspension to attain greater resistance. The result is a versatile shock absorber that can easily adopt to various road conditions. The effects of constant bounce, sway, brake dive and acceleration squat are thus significantly reduced.
