SBC Serpentine Upper Water Pump Pulley, 1 to 1 - 3402

The PRP Serpentine Upper Water Pump Pulley (Part #3402) is machined to run at a 1:1 ratio with PRP's matching serpentine crankshaft pulley, keeping accessory drive speeds consistent on Small Block Chevy (SBC) engines. It mounts to the water pump for a clean serpentine belt conversion.

Designed for racers converting to a serpentine accessory drive, this upper pulley is built to hold up to the vibration and RPM demands of circle track and drag racing use. Pair it with PRP's matching 1:1 crankshaft pulley (Part #3403) for a complete, correctly matched serpentine drive setup.
