March Performance Serpentine Pulley Conversion Performance Series Kit 302/351W/C

March Performance's Performance Series serpentine pulley set replaces your low performance V-belt pulleys while retaining your standard rotation water pump. Designed for normal street driving and simple to bolt on, this pulley set increases horsepower 12.5-15 h.p. at the rear wheels by reducing accessory drag. CNC machined from solid billet 6061-T6 aluminum for extra strength and wear resistance, these pulleys will run perfectly true, eliminating thrown belts. Finished with a "No Polishing" clear powder-coat.
