Replace the original 3.00" supercharger pulley with METCO'S 2.60" overdrive pulley to add 3.5-4 lbs of boost to your Shelby Mustang. The 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 wear, and after anodizing the ring is pocket-milled for good looks.

We recommend the use of METCO's Auxiliary Idler Kit (Metco Motorsports PN MSI-90) with this supercharger pulley. When these two components are installed together, the vehicle's original serpentine belt can be re-used.

Note 1: Due to the extremely tight interference fit of the factory supercharger pulley on the Shelby GT500 and the weak design of the pulley itself, the factory pulley is often damaged upon removal.

You will need a METCO PULLEY REMOVAL AND INSTALLER TOOL to do this job and it can be found here:Pulley Puller/Installer

Note 2: Metco Motorsports offers a stock-sized 3.00" diameter supercharger pulley ring for this application in case the owner later wishes to return to the stock boost level. The pulley ring included with this kit can be unbolted and replaced with the available 3.00" ring in minutes with no special tools required.
