Whipple 10-Rib Super Charger 5 Bolt Pulley 3.125″ in Black

The Whipple Supercharger pulley is made of 6061-T6 billet aluminum and anodized for wear and environmental protection. All pulleys are engraved with the running diameter size and state-of-the-art lightweight pockets to lower reciprocating mass and act as a guard feature to help unwanted belt wandering during hard running. The dimension of each supercharger pulley is based on the running diameter.

Additional Product Details:

• The standard finish is black hard coated anodized.
• Whipple Supercharger pulleys are specific to the application. Do not order this pulley for a different application.
• A general rule of thumb is every .125″ of pulley change is 1 psi of boost. We do not accept returns or exchanges for used pulleys.
