Stock pulleys rob you of precious horsepower on boosted applications. Slipping belts reduce your peak boost potential, and increase the amount of time to reach maximum boost. Our 8 rib kits increase grip by 25%, and that means more horsepower. Mate this kit with our ripped supercharger pulley (sold separately), and realize the maximum potential of your supercharger. Kit includes one power steering pump pulley, one alternator pulley, two idler pulleys, and two spacers for the idler pulleys.
