2005-2010 Mustang GT 4.6L BBK Underdrive Pulleys

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. These means less power is available when you press the pedal. But, do these creature comforts really need all the power they use? Nope.

BBK's 2005-2010 Mustang GT under drive pulley kit will give back 8-10 horsepower drained by your accessories. Under drive pulleys run slower than your Mustang's stock accessory pulleys, providing less power to accessories and more to the rear wheels.

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

Note: Underdrive pulleys are for naturally aspirated Mustangs only. They will actually decrease power on supercharged Mustangs. If you have a supercharged Mustang check out an overdrive pulley.
