ASP Part Number: 526400

Underdrive crank pulley for all 2005-2009 4.0L V6 Mustangs.

Looking to improve the performance of your V6 Mustang while improving gas mileage as well? You have found what you need!

This 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!

Requires a new belt.
