12-RIB 6-BOLT CRANK PULLEYS

Whipple 12-Rib 6-Bolt Crank Pulleys

Whipple 12-rib 6-bolt crank pulleys are built for Whipple supercharger applications that require a durable, high-quality crank pulley solution. Machined from billet 6061-T6 aluminum, these pulleys are designed to deliver strength, reduced mass, and the clean fit expected from a Whipple component.

The universal 6-bolt pattern fits most 3V and serpentine base crank pulleys, making these a versatile option for compatible Whipple applications. Each pulley features an anodized finish and lightweight pocketing to help reduce rotating mass while maintaining the durability needed for demanding supercharged use.

Available in multiple sizes, these crank pulleys are commonly associated with Whipple marine and performance applications, including Chevrolet Big Block, Mercury Marine 454/502 Magnum MPI, Mercury Racing 500 HP Carbureted, Mercury Racing 500 HP EFI, Mercury Racing 525 HP EFI, and Mercury Racing 575SCI categories.
