Vortech Superchargers 10-Rib 2.75" Pulley Tall Offset 4MA031-275
10-Rib Tall Offset Supercharger Pulley for Marine & Mopar Applications
The Vortech Superchargers 10-Rib 2.75" Tall Offset Pulley (PN 4MA031-275) is engineered for specialized Vortech Marine systems and Paxton Small Block and Big Block Mopar supercharger applications that require a tall-offset pulley design. This precision-machined pulley is designed to maintain correct belt alignment in applications where standard-offset pulleys will not properly align with the drive system.

It is commonly used in marine environments and Mopar applications that demand exact spacing and robust belt control.
