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.
Application:
These kits fit most mid and full size cars from the early 1950's and newer. Kit also fits 1969 and later Camaros and Novas. Other cars check water pump nose to radiator clearance. Long water pump kits extend out 8.5'' from the engine block with nose cover in place, plus clearance for mechanical or electric fans. Long water pump kits work with front motor mounts.
