DriveAlign® Overrunning Alternator Pulleys

Gates® DriveAlign® Overrunning Alternator Decoupler Pulleys allow the alternator to "free-wheel" or "overrun" every time the engine decelerates and provide vibration isolation within the Accessory Belt Drive System resulting in smoother engine performance and efficiency and increased belt and component life.
