It is a 7-groove pulley that mounts to the front of the crankshaft to absorb and reduce torsional vibrations produced during engine operation. A failing damper can lead to excessive engine vibration, premature wear on bearings, and potential crankshaft failure, so it is typically replaced when the rubber isolation ring shows signs of cracking, deterioration, or when the damper wobbles.
