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 setup 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 tuneability 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). Setup manual includes instructions for most common applications.
