A different version of our popular clutch kit for the Polaris RZR models. It has a different secondary clutch and calibration than earlier year models. This kit has a different set of flyweights and a new set up guide that is specific to this model year. The flyweight design allows for the use of more flyweight mass in a different configuration than the factory clutch calibration, and offers tunability to adjust for case specific applications including tire sizes, elevation, etc. Please note the applications listed for this kit. The regular RZR (non-“S”) stock clutching is a good calibration for stock tires. Ultimate RPM control (can be adjusted for modifications). Set up manual includes set up instructions for most common applications.
