2.60" Supercharger Pulley Kit

2007 and Newer Shelby GT500

One of our most popular products!

Replace the original 3.00" supercharger pulley with our 2.60" overdrive pulley to add 4-5 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 our Auxiliary Idler Kit (Metco Motorsports PN MSI-90, http://www.metcomotorsports.com/proddetail.asp?prod=MSI%2D90) 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.  To change pulleys, the use of a hydraulic press is recommended but a high-quality pulley removal and installation tool can also be used.  We manufacture our own pulley tool and it is available under Metco Motorsports PN MPT0001, listed elsewhere in this section. 

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 2.60" pulley ring included with this kit can be unbolted and replaced with the available 3.00" ring in minutes with no special tools required.
