We're proud to announce the release of the Lethal Performance by Griptec supercharger pulley kit for the all-new 2020 Shelby GT500. From the factory, the new Shelby GT500 comes with a 3.085" supercharger pulley which makes an estimated 12psi of boost. We worked closely with our friends over at Griptec to come up with an interchangeable pulley kit that uses a hub and ring design giving the customer several options in pulley sizes to choose the boost level you're wanting to make. Each Lethal Performance by Griptec pulley kit comes with the supercharger hub, supercharger pulley ring, and the hardware needed to install the ring onto the hub. The rings are being offered in sizes from 2.35" through 3.15". What can you expect from this kit? More boost, more horsepower, and more torque for your 2020 Shelby GT500.

For every .10 smaller in pulley diameter, we expect to see a 1psi increase in boost.
