The brake system of a vehicle depends on shock absorbers to perform effectively. Car shock absorber components have a crucial role in dampening or absorbing the compression and rebound of the springs and suspension, which helps to regulate excess spring motion and maintain tire-to-road contact. Whenever a vehicle encounters a bump or dip on the road, the suspension and springs move to absorb the energy and keep the tire in contact with the road. Shock absorbers are responsible for converting the kinetic energy of the spring into thermal energy, which gets dissipated in the hydraulic fluid.

Monroe shock absorbers are oil-filled cylinders that have a piston inside, which moves up and down as the suspension moves. This movement forces small amounts of fluid through tiny holes in the piston head, slowing down the suspension and reducing the compression and rebound of the springs. Shock absorbers are velocity-sensitive, which means they provide more resistance when the springs are moving faster.
