The ATI crankshaft damper is a 6.77-inch aluminum, three-ring damper with an 8-groove profile designed for Ecotec engines. It reduces torsional vibration and offers a compact diameter for engines where clearance is limited, while providing the groove pattern needed for accessory drive pulleys specific to Ecotec configurations.
