Billet Specialties crankshaft pulleys are precision CNC machined from forged 6061-T6 aluminum, ensuring unparalleled strength and balance.

WHY OPT FOR A BILLET PULLEY? The key advantage of a billet aluminum pulley lies in its consistent density. Unlike cast pulleys, where aluminum is poured into a mold and allowed to cool, the billet pulley maintains uniform density throughout. Variations in density, common in cast pulleys, can lead to imbalances, causing vibrations at high RPMs. Our billet pulleys, with their even density, ensure a true and balanced pulley drive system.
