Supercharger Pulley Ring (Ring Only)
2007-2012 Shelby GT500
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 the pulley on a Shelby GT500:
MSPR3.00: Stock diameter, no change MSPR2.60: +3-3.5 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 MSI-90D idler kit is listed elsewhere in this section.
Kit includes (1) pulley ring - no pulley hub or hardware is included. Please make your selection below.
Part Numbers: MSPR2.60, MSPR3.00
Note: The 2.60" ring is the ring shown with the machined (silver) pockets around each fastener. The 3.00" ring does not have these pockets in the interest of a more stock appearance.
