What is compression damping?
A damper, also known as a shock or strut, has two ranges of motion. As the shaft of the damper compresses into the damper body, the damper is in compression. In application, as your vehicle enters a bump, the damper will compress. Compression damping is the primary factor in ride quality, road compliance and steering response. Compression force can also act as additional spring rate in a car. It is possible to run a strong compression damper, with a very soft spring. In comparison, it is not good to run a very strong spring with a very soft damper.
