This clutch kit is the ultimate kit for the PRO R 4 CYLINDER models that have a turbo or supercharger installed. It offers awesome belt grip, hard pulling acceleration, lighting fast back shifting, totally eliminates belt slap, much cooler belt temps, and adjustability.
This clutch kit covers boost levels of 7psi-17psi. If you are running higher than 17psi boost levels, I recommend you purchase some of our tungsten slug sets. For 18-20 PSI you would want to put one tungsten slug set in the tip of each clutch weight. If you are running 20-23 psi, you would want two slugs per clutch weight, one in the tip and one in the next hole back. The tungsten slugs are listed separately on our site and sold individually.
