De-clutching pulley / alternator - DriveAlign®
The DriveAlign was created by drive system specialists with the premise of avoiding reducing belt performance when the vehicle slows down because of the use of heavier alternators by manufacturers because of seat heating, air conditioning and other additional components that needs more electrical power. Instead of using a common solid alternator pulley, the overrunning alternator pulley allows the alternator to free-wheel or overrun every time the engine slows down and takes in vibrations. Every recent car model has such a device and the inclusion of DriveAlign overrunning alternator pulley to its range, it completes the need for a complete overhaul of the accessory belt drive system.
