Almost every recent car model is equipped with an overrunning alternator pulley. That is why Gates decided to add a line of DriveAlign® overrunning alternator pulleys (OAP) to its range. Gates now has everything you need to guarantee a fully reliable accessory belt drive system: from multi-ribbed belts over torsional vibration dampers to expert tools.
Benefits

  • Allows the use of alternators with increased power output.
  • Reduces the influence of the alternator mass on the belt drive.
  • Decreases wear and tear on all belt drive components.
  • Eliminates belt slip and therefore noise.
  • Absorbs vibrations and fluctuations.
  • Increases the life span of all accessory belt drive components.
