Compatible/Replacement for FORD MUSTANG 5.0 BILLET ALUMINUM SERPENTINE PULLEY SET - BLUE
Ford Mustang 5.0L Underdrive Pulley Set. Anodized blue billet aluminum 6 groove serpentine alternator, crank and water pump pulley set. The pulleys are CNC-machined from the lightest, most durable materials possible billet aluminum. Underdrive pulley systems increase engine horsepower by reducing the amount of power required to drive external engine accessories.

Typically, a set of CFR pulleys will increase horsepower by 11-15, and increase mileage
