Billet Specialties water pump pulleys are meticulously CNC machined from forged 6061-T6 aluminum, ensuring unmatched strength and balance. Engineered for v-groove style belts on Chevy engines, each pulley undergoes a mirror finish polishing process and comes complete with stainless steel mounting hardware. BILLET PULLEY NOSE CONES are available separately.

WHY OPT FOR A BILLET PULLEY? Choosing a billet aluminum pulley offers the advantage of consistent density. In contrast to cast pulleys, where aluminum is poured into a mold and left to cool, our billet pulleys maintain uniform density throughout. Variations in density, typical in cast pulleys, can result in imbalances, causing vibrations at high RPMs. Our billet pulleys, with their uniform density, ensure a genuine and balanced pulley drive system.
