Take the Power Back

Your 2005-2010 Mustang GT's engine does more than send power to the rear wheels. It has to run all your car's auxiliary systems - from air conditioning to head lights. This means less power is available when you press the pedal. But, do these creature comforts really need all the power they use? No, they don't. BBK's 2005-2010 Mustang GT underdrive pulley kit will give back 8-10 horsepower drained by your accessories. Underdrive pulleys run slower than your Mustang's stock accessory pulleys, providing less power to accessories and more to the rear wheels.

Quality & Convenience

BBK's 2005-2010 Mustang underdrive pulleys are SFI certified and use your Mustang's factory serpentine belt. Installation is straight-forward. The new pulleys just bolt on using factory mounts.

Important Notes:

  • Underdrive pulleys are for naturally aspirated applications only. They will actually decrease power on supercharged Mustangs. If you have a supercharged Mustang, see our selection of overdrive pulleys.
  • This item usually ships out of our warehouse in: 1 day.
