Which component absorbs shock in a vehicle's suspension system?

The component that absorbs shock in a vehicle's suspension system is primarily the shock absorbers, also known as dampers. Their main function is to control the impact and rebound movement of the vehicle's springs and suspension, optimizing ride quality and handling by absorbing and dissipating the energy produced by shocks and vibrations from the road.

While struts also perform some of the same functions as shock absorbers since they often contain a shock absorber within them, the term "shock absorbers" specifically refers to the standalone components designed predominantly for that purpose. Struts serve as structural components of the suspension system as well, providing support for the vehicle and assisting in suspension alignment.

Brake pads, in contrast, are essential for slowing down and stopping the vehicle, while wheel bearings facilitate smooth wheel rotation and support the vehicle's weight. None of these components are primarily designed to absorb shocks like shock absorbers do. Understanding the specific roles each component plays helps clarify why shock absorbers are the correct answer in the context of shock absorption within the suspension system.
