The ATI 7.65-inch aluminum damper is an OEM-size, two-ring unit with an 8-groove pulley configuration for LS7 and Y-body Gen 5 Z28 applications, also fitting many LS3 installations where no air conditioning is present. It provides harmonic control and factory-style pulley spacing for rebuilds or swaps that need stock dimensions without A/C accessory accommodation.
