For automotive vehicle applications that include ADP as Original Equipment.
The Dayco ADP has a one-way clutching capability which allows it to isolate and dampen the drive from the alternator upon deceleration. These specially designed pulleys reduce belt slippage during rapid acceleration or deceleration and reduce noise and stress on the drive belt and other accessories. Also designed to increase alternator and belt drive life as well as improve the variation of drive belt tension, Dayco offers a full line of high-quality ADPs where vehicle applications call for it. Proper tools must be used to remove and install ADPs.
