Every Whipple Supercharger pulley is made of 6061-T6 billet aluminum and anodizied for wear and envoirnmental protection. Each pulley is engraved with the running diameter size and state-of-the-art light weight pockets to lower recipocating mass as well as a guard feature to help unwanted belt wandering during hard running. Standard finish is hard coated black anodizied. Dimension of each supercharger pulley is based off of the running diameter.
* A general rule of thumb is every .125" of pulley change is 1psi of boost. There are NO returns or exchanges for used pulleys.
** Whipple Supercharger pulleys are specific to the application. Do NOT order this pulley for a different application.
