The ATI crankshaft damper is a 6.78-inch aluminum, three-ring damper with a 6-groove configuration built for LT1 and LT4 engines used in Y‑body Corvette applications. Its aluminum construction reduces rotating mass while the three-ring design manages harmonic vibration and preserves fitment where Corvette front-end clearances and hub spacing are a concern.
