Metco 2.80'' Supercharger Pulley Kit for 07-09 GT500

One of our most popular products!
Replace the original 3.00"" supercharger pulley with our 2.80'' overdrive pulley to add 2-3 lbs of boost to your Shelby Mustang.  These kit includes a pulley hub machined from high-grade steel that presses onto the blower shaft.  The CNC-machined aluminum ring bolts to the steel hub using the supplied stainless steel fasteners and this two-piece design makes subsequent pulley ring changes a snap.
The steel hub is re-usable (unlike aluminum one-piece blower pulleys)and is black oxide-coated for long lasting surface protection.  The aluminum ring is hard-coat anodized in black to resist surface wearand after anodizing the ring is pocket-milled for good looks. 
We recommend the use of our Auxiliary Idler Kit (Metco Motorsports PN MSI-90 with this supercharger pulley.  When these two components are installed togetherthe vehicle's original serpentine belt can be re-used.
