METCO Overdrive Crank Pulley
2005 & Newer Mustang 3V with Supercharger, 8-Rib Belt

This overdrive crank pulley assembly is designed for 3V Mustangs equipped with an aftermarket supercharger. The pulley is oversized to provide additional blower speed while avoiding the belt slippage issues associated with smaller supercharger pulleys.

The assembly is based on an OEM Ford harmonic balancer, which is precision-machined at our shop to accept the 7.55" billet overdrive pulley ring. The two components are fastened together using six black oxide-coated Grade 8 bolts.

This pulley assembly installs as a direct replacement for the factory component, and is compatible with both 6 and 8-rib drive belts. A longer supercharger belt and additional tuning may be required.
