All Pulleys are Not Created Equal.

When it’s time to replace an overrunning alternator decoupler (OAD), don’t skimp with inferior, “near-match” parts like solid, one-way clutches or isolator pulleys. Go with Gatorback® OADs.

Designed and produced by the Litens Automotive Group as original equipment on many North American and European vehicles, OADs are now available for the auto parts aftermarket, and the best way to ensure you’re using the right pulley for the job.

Controlled Vibration. Smooth Performance.

Lower System Tension Improves:

  • Vehicle Noise Level, Vibration, Harshness
  • Front-End Accessory Drive Component Life
  • Fuel Economy

Tuning:

  • For Cylinder Deactivation
  • Idling and Cruising
  • Transmission Shift Belt Noise

Gatorback® OADs include a patented internal torsion spring that is tuned to the specific engine application. The spring absorbs base-engine vibration before it reaches the alternator. It also connects, but isolates the alternator pulley from the rotor, which in turn effectively eliminates the vibration felt by the driver. OADs include a one-way clutch (decoupling feature) that enables the alternator to coast freely if belt speed suddenly decreases, such as an engine shut-down or a transmission shift.
