The ATI crankshaft damper is a 6.78-inch aluminum three-ring damper with a 6-groove profile that includes a 28-tooth, 8mm HTD drive rear provision for LS1/LS2/LS3/LS6 and L76 engines (1997–2013). It provides harmonic damping while integrating an HTD timing drive interface, suitable when a toothed rear drive and three-ring construction are required.
