Description

The PRP Serpentine Crankshaft Pulley (Part #3403) is machined to run at a 1:1 ratio with PRP's matching serpentine water pump pulley, keeping accessory drive speeds consistent on Small Block Chevy (SBC) engines. It bolts directly to the crankshaft in place of a stock or V-belt style pulley for a clean serpentine belt conversion.

Designed for racers converting to a serpentine accessory drive, this 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 water pump pulley (Part #3402) for a complete, correctly matched serpentine drive setup.
