SLP 07-09 Shelby GT500 Supercharger Pulley Tool Package

One of the easiest ways to pump up the power of your supercharged 2007-08 Mustang Shelby GT 500 is to increase the factory boost level. SLP's 2.70" blower pulley provides approximately 3 additional psi of boost, resulting in gains of up to 35 rear-wheel horsepower, but not at the cost of reliability or durability. It's made from powder-coated ductile iron for maximum durability and features extra-deep grooved ribs to eliminate belt slippage. Retains use of the factory serpentine belt.

This package also includes a custom installation tool that greatly simplifies the pulley-installation and disassembly process (conventional 3-plung pullers will not work). All necessary hardware and detailed installation instructions are included. Best of all, you'll save $10 over the cost of purchasing the parts individually!
