Which component is used to dampen suspension movement by forcing hydraulic fluid through an orifice?

Damping suspension movement is achieved by a device that contains a piston moving inside a cylinder and forces hydraulic fluid through calibrated orifices or valves. As the wheel moves, the piston pushes fluid through these restrictions, creating resistance to both compression and rebound. This viscous flow converts kinetic energy into heat, reducing oscillations and helping keep the tire in contact with the road. The valve setup can tune how stiff the damping is for different conditions. A sway bar slows body roll but doesn’t dissipate energy this way; a control arm is just a linkage; a spring stores energy and provides the primary restoring force. So, the component that dampens movement by forcing hydraulic fluid through an orifice is the shock absorber.
