The ATI 6.78-inch aluminum damper is a 6/4-groove, two-ring unit intended for Nissan SR20 front-wheel-drive street applications. Built to provide crankshaft harmonic control while using an aluminum outer for reduced rotating mass, this damper suits street rebuilds and upgrades where correct pulley groove count and front accessory alignment are required.
