GripTec pullies are the premium upgrade for any supercharger build. Belt slip is a very common issue that causes boost loss on superchargers. Often belt slip is noticed when the system squeals, squeaks or boost falls off. Supercharger systems running 3.4 upper pulleys can see as much as a 1.5 psi gain when adding a Griptec pulley. We sell extra grip supercharger pullies for Vortech, Paxton, Whipple, Procharger, VMP and more. Choose from 6, 8 or 10 rib configurations.
