These are our billet 2-piece lower crank pulley sets designed for the forced induction guys looking to raise the boost. The set comes complete with a billet crank hub, billet outer ring, and complete assembly hardware. The pulleys are CNC'd from 6061-T6 billet alluminum and have a unique feature. They come 2-piece for a reason. This design allows you to interchange different ring sizes without having to purchase another complete pulley set. We have three outer ring sizes to help you dial in the boost. We have a 6.5", 7.0", and 7.5". This pulley set will allow you to increase boost if you do not desire to change out the blower pulley. This set will also allow you to increase boost above and beyond the upper pulley change. We have plenty of combinations for you.
