Vortech Superchargers 10-Rib 7.0" Crank Pulley Universal (Chevy / Ford / Mopar) 4MA018-051
Universal 10-Rib 7.0" Crank Pulley for Vortech Supercharger Drives
The Vortech Superchargers 10-Rib 7.0" Crank Pulley (PN 4MA018-051) is a universal, flat-backed crank pulley engineered for high-performance Vortech supercharger drive systems where increased belt traction and reliability are critical. The 10-rib configuration significantly increases belt contact area, helping reduce belt slip in higher-load and higher-boost applications.
This pulley is drilled to support multiple crankshaft bolt patterns, allowing fitment across Chevrolet (3-bolt), Ford (4-bolt), and Mopar (6-bolt) platforms. Its universal design makes it an excellent choice for custom supercharger builds, race applications, and upgraded drive systems requiring a robust crank pulley solution.
