With almost 100 years of innovation and experience, Gates offers the highest quality OE parts on the market today.

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. The line consists of overrunning alternator decoupler pulleys and one way clutches (not interchangeable).
Gates engineers our automotive aftermarket parts in partnership with the top automotive OEMs around the world, so you can trust premium-grade automotive parts with exceptional fit, function and performance, and a durable component construction that's built to last.
