Features: 2 1/2" Diameter Polished Fits most GM, Delco, and Ford alternators Billet Specialties manufactures the most balanced alternator pulley and fan combo in the industry by machining the unit out of one solid piece of aluminum. This 1-piece pulley and fan combo features a bolt on nose cone to hide the alternator nut and washer, stainless hardware included Billet Specialties alternator pulleys are CNC machined from forged 6061-T6 aluminum for the ultimate in strength and balance. WHY USE A BILLET PULLEY?: 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. Billet Specialties' pulleys are equally dense throughout; equal weight translates to a true and balanced pulley drive system.
