SFPH now introduces the all new Roush 6 Rib Keyed Style 2.57" Supercharger Pulleys for all 2006 to 2007 Roush Style Mustang With Model 90 Supercharger.

Expect 3.5 to 4 psi more boost at wide open throttle, for a total of 9.5 to 10 psi, versus the stock 3.25" stock pulley that comes on all Roush Supercharged Mustangs that only produces 6 psi at wide open throttle.

These Pulleys are made from 6061 T6 Billet Aluminum and are Keyed to the "Exact Factory Specifications" as the stock supercharger pulley. 

"Make Sure You Check The End Tolerance Of Your Snout Housing To Make Sure This Pulley Will Fit Properly" Failure To Do This, Will Not Allow You To Install This Pulley Properly, As All Pulleys Smaller Than a 2.80" Will Require The End Of Most Snout Housing To Be Machined Down To Clear The Inside Of The New 2.57" Roush Style Supercharger Pulley"
