    Long Water Pump/Standard Rotation

    Replace your low performance v-belts, pulleys and brackets with this compact Mid Mount kit that places your alternator and power steering pump below the center line of the water pump. Simple to bolt on, while retaining your standard rotation water pump. Serpentine belts eliminate belt slipage and throwing. Kits are available in High Water Flow ratio for increased cooling. CNC machined from solid billet 6061-T6 aluminum. This translates into a spectacular looking new machine finish with perfect fit and extra high strength. All of these billet pulleys and brackets have a ''No Polishing'' maintenance-free clear powdercoating. Kits come complete with stainless steel tensioning rod, chrome-moly rod ends and necessary mounting hardware.
