BBK 96-01 Mustang 4.6 GT Cobra Underdrive Pulley Kit - Lightweight CNC Billet Aluminum (3pc)

Doing some work on your 1996-2001 Mustang GT or Cobra and looking for a little extra pep? Swapping out the stock pulleys for a set of BBK underdrive pulleys can help free up some horsepower. These kits work by slowing down your engine's accessories, like the alternator and water pump, which reduces the drag on the engine. Less drag means more of the engine's power can go to the wheels.

This 3-piece kit is made from lightweight, CNC-machined billet aluminum, which also helps reduce rotational mass compared to the factory steel pulleys. BBK designs these as direct bolt-on replacements, so you can reuse your existing serpentine belt and factory hardware. They're made to retain proper cooling and charging system function, so you don't have to worry about sacrificing reliability for performance. This kit includes the crank, water pump, and alternator pulleys, and is designed for Mustangs with the short-style water pump.
