Product Details
You get a 3-piece underdrive pulley kit from BBK in this Power-Plus Series kit. This kit replaces your stock crank, water pump, and alternator pulleys on your 2001-2004 Ford Mustang GT or 2000-2001 Cobra. Underdrive pulleys work by slowing down your engine's accessories, which reduces the horsepower they draw from the engine. This means more power goes to your wheels. BBK also uses lightweight CNC machined billet aluminum, which further helps performance by reducing rotational mass compared to the heavier factory pulleys.
These pulleys are designed as direct bolt-on replacements. They are made from CNC machined billet aluminum and retain full cooling and charging system function. The kit includes all required hardware and allows you to reuse your existing serpentine belt.
