These CNC Billet Aluminum underdrive pulleys fit all 1979-93 5.0 liter Mustangs.
Each kit includes alternator, water pump and crankshaft pulleys and have been dyno-proven to yield approximately 15 horsepower!!!
The way these pulleys work is by slowing down the front accessories, which rob the engine of horsepower, which in turn means more horsepower to the rear wheels
All kits include all hardware and instructions for a simple installation. Shipping is always free at Stage 3 Motorsports.
