Replace the original 3.00" supercharger pulley with one of our precision-made supercharger pulley kits to add 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 nickel-plated 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 (2.60" ring only, shown second from left).  

We recommend the use of our 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.  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:  In addition to the overdrive (smaller) supercharger pulleys, Metco Motorsports offers a stock-sized 3.00" diameter supercharger pulley ring for this application.  If the need arises to return to the stock boost level, pulley rings are available separately (listed elsewhere in this section) and can be changed in minutes.

Note 3:  The 2.60" pulley is also offered in a machined-finish.  Please call or email to check availability. 

We also offer a front pulley cover for the black-anodized 2.60" supercharger pulley.  This pulley cover installs over the front of the 2.60" pulley to make it more stock-appearing.  This cover is listed elsewhere in this section under PN MSP260CVR.

The steel pulley hub is nickel-plated and is no longer offered in the black oxide finish shown in some of the images above.

If your 2007-2012 GT500 is equipped with our popular 2.60" supercharger pulley upgrade, you may add this stock-appearing pulley cover for a stealthy look.  This cover is precision-machined from billet aluminum and then black-anodized, and it simply slides over the 2.60" pulley.  The cover is secured using a stainless steel socket-head fastener (provided) that threads into the hole at the end of the supercharger shaft. .

*Please note that this pulley cover is only compatible with Metco Motorsports 2.60" supercharger pulleys manufactured after Novermber 2012.  If you have doubts about compatibility with your pulley, measure your pulley ring and its widest point (just forward of the belt surface) to confirm an OD of 69.5mm.  If your pulley measures 72mm, it is the earlier design and this cover will not fit.

These pulley rings are designed for use with Metco Motorsports two-piece supercharger pulleys.  If you already have a Metco supercharger pulley on your GT500, one of these rings is all that is needed to change the boost level on your vehicle.  These pulley rings will bolt to your existing pulley hub using the same (5) fasteners, and no special tools are required for the change.

Our pulley rings are precision-machined from billet aluminum and then black anodized for long lasting surface protection. 

Listed below are approximate boost gains that can be expected when installing these pulleys on a Shelby GT500:

MSPR3.00: Stock diameter, no change  MSPR2.80:  +2-3 lbs  MSPR2.60:  +3-4.5 lbs

We recommend the use of our Auxiliary Idler Kit with the 2.60" supercharger pulley to maximize belt wrap and to minimize belt slippage.  Our idler kits are listed elsewhere in this section.  

Kit includes (1) pulley ring.  Please make your selection above.

This is the same pulley hub included with the Metco Motorsports supercharger pulley kits (MSP2.60, MSP2.70, MSP2.80, & MSP3.00) listed in this section.

This kit includes the CNC-machined pulley ring mounting hub and five stainless steel hub-to-pulley ring fasteners with lockwashers.  The pulley hub is nickel-plated for long lasting surface protection.

This pulley hub is compatible with any of the Metco Motorsports GT500 pulley rings listed in this section.

Note:  One competitor offers a 'Metco style' supercharger pulley hub with a relaxed interference fit to save time during installation.  Please note that the genuine Metco pulley hub is precision-machined for the appropriate fit on the shaft necessary to resist the high loads imparted by the supercharger belt in the GT500 application.
