10 Extra Horsepower
Quick bolt-on horsepower is easy to find with a set of BBK Performance underdrive pulleys. These high-quality pulleys can add up to 10 rear wheel horsepower onto your 2001 to 2004 Mustang GT or 2001 SVT Cobra. The pulleys directly replace your highly inefficient factory accessory pulleys and slow down the rotational speeds of your alternator, water pump, and crankshaft to allow your engine to put more power to your wheels.
High-Quality Billet Aluminum
Each of these SFI-approved underdrive pulleys are CNC machined from billet aluminum, making them some of the most durable designs on the market. This complete pulley kit comes with a water pump, alternator, and crankshaft pulley that drop right into place of your stock pulleys. BBK even made the necessary changes to its water pump pulley so that it fits the revised design of the post April 2001 Mustangs. This pulley kit comes with all necessary hardware and instructions.
Note: Not recommended for 03-04 Supercharged Cobras
