March Pulley Sets are precision CNC machined from 6061-T6 aluminum for extra strength, durability and trueness. Finished with a ''No Polishing'' clear powdercoat. Early model Chrysler engines are easily converted from the old low performance V-belts to smooth operating 1'' wide serpentine belts while retaining the standard rotation water pump. Later model engines that already have a serpentine belt system will benefit from March Performance pulleys by reducing accessory drag which will increase horsepower. Performance Ratio Series Increases horsepower by reducing accessory drag. 12 h.p. at rear wheels typical. Eliminates belt throwing. Designed for normal street driving. Power & Amp Ratio Series Increases horsepower by reducing accessory drag. 10 h.p. at rear wheel. Design for vehicle with high amperage needs. Magnum engines only.
