Roush Supercharger Pulley
2005-2008 Mustang GT
This 6-rib 2.57″ pulley is a very popular upgrade for owners of new Mustangs equipped with Roush superchargers who wish to add more boost.
The pulley is CNC-machined from high-grade steel for precision fit and extreme durability, and the surface is black oxide-coated to prevent rust. The pulley is keyed and installs as a direct replacement for the original Roush supercharger pulley.
