Billet Specialties BB Chevy Double Groove Crankshaft Pulley - BB Chevy - Long Water Pump

Billet Pulleys
The benefit of a billet aluminum pulley over a cast pulley is equal density. With a cast pulley, the aluminum is poured into a mold and then allowed to cool. This process can create variations in density throughout the pulley. Dense areas are heavier than the more porous areas causing the pulley to vibrate at high RPM. Our billet pulleys are equally dense throughout; equal weight translates to a true and balanced pulley drive system.

Crankshaft Pulleys
Our crankshaft pulleys are machined from 6061-T6 billet aluminum and polished to a mirror finish. Available for small and big block Chevy applications, with either a long or short water pump.
