GatesAlternator Decoupler Pulley

Gates DriveAlign 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. This results in smoother engine performance, efficiency and increased belt and component life. The line consists of overrunning alternator decoupler pulleys and one-way clutches (not interchangeable).
