The original pulley installed on the GT500 has an effective diameter of 3.085″, and this pulley size generates approximately 12 lbs of boost. We suggest consulting your tuner to determine the pulley size best suited for your application.  All components are available separately, so once you have our pulley on your GT500, a boost change is as simple as changing the outer pulley drive ring. All boost level changes require the appropriate PCM revisions and the proper supercharger belt. Please note that quoted boost gains are approximate, and that your results may vary.

 For all supercharger pulley changes, the PCM calibration for the vehicle must be revised to accommodate the increased boost level.

 User assumes all risks. Installation of this pulley may affect your warranty. Off road use only.
