Show original supplier description
The Litens 920666K is a clutched supercharger pulley upgrade kit designed to enhance the performance and longevity of your Hellcat, Trackhawk, Demon, or Redeye supercharger. Developed with the OEM Hellcat clutched pulley design, this component from Litens Automotive aims to reduce stress and minimize associated wear on your supercharger's bearings and rotors, promoting a longer service life. This comprehensive kit features a 2.72" Litens Automotive Supercharger Pulley, an end cap to act as a dust/tamper shield, a 17mm installation tool for easier mounting, and a Gates HD Belt. The 2.72" pulley is engineered to increase boost levels, producing approximately 16 PSI on Hellcat and Trackhawk superchargers, and up to 20 PSI on Demon and Redeye superchargers at sea level. Installation of this pulley kit necessitates the use of larger fuel injectors and a custom engine tune to safely manage the increased boost and air/fuel ratios. While pinning the crankshaft pulley is not believed to be required for this specific pulley, it is advised to consult with a professional or review installation guides for complete safety assurance. Purchasers should also verify local and state laws regarding emissions compliance before buying this product.
