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. Southwest Speed pulleys are equally dense throughout; equal weight translates to a true and balanced pulley drive system.
