March's “V-Groove” pulleys do exactly what they're supposed to: Increase horsepower by reducing accessory drag. They do this so well, you can expect 12.5 to 15 more horsepower at the rear wheels! March pulleys are CNC-machined to run perfectly true and to eliminate belt throwing. These pulleys were designed for normal street use—perfect for your daily driver. Made from 6061-T6 aluminum for extra strength and durability.
