Shock. Absorber.
A Shock Absorber is a device that controls the spring oscillations when the vehicle goes over various road irregularities, so the vehicle's tires remain in contact with the road. In some cases, Shock Absorbers have a secondary function as a suspension limiter to prevent the suspension from either over-extending and/or over-compressing. Code-PYW. Assembly - SHK. Bolt. Strut.
