    All In One Kit. VMP Tuning realizes that when you go to install one of their supercharger pulleys on your GT500 for big power gains you are going to need more than just the pulley itself. That is why VMP offers an all in one kit for a hassle free installation. Their kit includes a 2.4" Supercharger Pulley, a 90MM Idler Pulley and their Ultimate Pulley Tool Installation & Removal Kit.

    2.4" Supercharger Pulley. Increase the boost and the power of your Shelby GT500 by installing a VMP Tuning 2.40" Supercharger Pulley. A reduction of just 0.125" in pulley diameter will yield an increase of about 1 PSI in boost. VMP's 2.4 in. Supercharger Pulley will increase the boost of your GT500 by 2-3 PSI, when compared to the stock 2.7" pulley. VMP Tuning manufactures their Stock Look Pulley to OEM specifications from high-grade steel for strength and durability. VMP then completes their pulley in a black powder coated finish, which is identical to the original, so no one will ever notice your hidden performance upgrade.

    90MM Idler Pulley. VMP includes their 90MM Idler Pulley to take up the excess belt slack that is created when installing a smaller diameter supercharger pulley. If this slack is not removed it will cause belt slippage which will actually rob you of the power you are trying to make. Engineered using the same size and brand of heavy-duty bearings as the factory idler, VMP's 90MM Idler Pulley eliminates the need for a double bearing design.

    Removal and Installation Tool. VMP has made removing your old stock pulley and installing your new pulley easy by including their very own Ultimate Pulley Tool Installation & Removal Kit. VMP's Tool utilizes a clamshell design that clamps onto the pulley and holds it by the ribs, not the face. This unique clamshell design applies uniform force around the circumference of the pulley for easy damage free removal and installation. CNC-machined from solid billet aluminum, VMP's Ultimate Pulley Tool features fine threaded bolts, a D-3 bearing and grease to make operation a painless experience.

    Required Upgrade. For proper operation and maximum power potential this VMP 2.4" Supercharger Pulley will require reprogramming the vehicles computer. AmericanMuscle recommends a custom tune with a Mustang Handheld Tuner to reprogram the vehicles computer (ECU) for proper operation.

    Application. This VMP Ultimate Pulley Tool with 2.4 in. Supercharger Pulley and 90MM Idler Pulley is specifically designed for use on the 2013 to 2014 Shelby GT500 Mustangs equipped with the stock 2.3L TVS supercharger.
