Looking to improve the performance of your V6 Mustang while improving gas mileage as well? You have found what you need! Our underdrive crank pulley/harmonic damper assembly directly replaces the factory unit and provides an 8 to 10 rear wheel horsepower increase by reducing parasitic accessory drag.
This reduction in drag also provides an increase in gas mileage as well!
