    Warranty Information
    • Product Details

      Part No. 920004A

      Warranty Details (1 YR REPLACEMENT IF DEFECTIVE)

      Litens Automotive is the inventor and patent holder of OAD decoupling alternator pulleys. This replacement pulley is offered as an upgrade to the original one-way clutch design for this police vehicle application . The Litens OAD type pulley is designed to free-wheel in one direction and, with an internal spring and damping device, softly engage in the opposite direction. The OAD is designed as a sacrificial part of the front-end accessory drive system, protecting other belt driven component as well as the alternator. The correct decoupler pulley ensures smooth, quiet performance, as well as, increasing vehicle gas mileage. Under normal driving conditions, the original pulley will require replacement in approx. 45,000 - 75,000 miles.
