Part Number: 4100
MAC Black Billet Steel Underdrive Pulley Set for all 1979-1993 5.0L Mustangs.
As most auto enthusiasts know, if you can reduce the amount of effort your engine takes to spin accessories, some extra horsepower is freed and makes it's way to your wheels. Made from billet steel, these underdrive pulleys are the easiest way to free up that lost horsepower from your over sized factory pulleys.
Smaller pulleys reduce the amount of power required to drive your alternator, water pump, power steering, air conditioner, etc. This results in improved horsepower gains that can truly be felt!
This set contains 3 black powder coated underdrive pulleys for the crank, water pump and alternator. Hardware included.
*The original accessory drive belt can still be used.
