How does a Car Shock Work?

Suspension is the term given to the system of springs, shock absorbers and linkages that connects a vehicle to its wheels. Suspension systems serve a dual purpose – contributing to the car's handling and braking for good active safety and driving pleasure, and keeping vehicle occupants comfortable and reasonably well isolated from road noise, bumps, and vibrations.

The internal components of the shock are the surrounding case that has a shaft with a piston and on either side of the piston is a set amount of gas that will compress and firm up. The Spring help aid this process.
