Seat heating, air conditioning and other additional accessories require extra electrical power, which causes the vehicle manufacturers to utilise ever heavier alternators, compromising the belt performance during deceleration of the engine.

Drive system specialists created the overrunning alternator pulley which, as opposed to a conventional solid alternator pulley, allows the alternator to “free-wheel” or “overrun” every time the engine decelerates and absorbs vibrations.

Almost every recent car model is equipped with such a device and by adding the OE equivalent DriveAlign  overrunning alternator pulley to its range, Gates can now offer the aftermarket all components necessary for a complete overhaul of the accessory belt drive system.
