Shown here is our billet aluminum Serpentine style single belt water pump pulley. Serpentine style belts are a newer, more modern setup which contains six separate ribs to help grip the much wider style belt. This helps to increase horsepower and virtually eliminates belt throwing and slippage. Machined from a solid piece of billet aluminum, you can't beat these for a great combination of performance, durability and good looks. And, of course we've got 'em at a price that can't be beat.
Works with all our "Serpentine" style crank and alternator pulleys. Don't forget our 109-1518 bolt kit, it is REQUIRED for use with this pulley.
