To fully capitalize on the increased power and improved engine efficiency provided by the Straightline Single Pipe, the clutch system must be recalibrated to transfer that power effectively to the snow. This complete clutch package is designed to do exactly that.\u003c\/p\u003e\n\u003cp\u003eEngineered specifically for Polaris 850 RMK, SKS, and Assault models operating between sea level and 3,000 feet elevation, this clutch kit delivers improved acceleration, stronger throttle response, faster backshift, and enhanced deep snow maneuverability for serious mountain riders.\u003c\/p\u003e\n\u003cp\u003eAt the center of the package is Straightline Performance’s proven fully adjustable weight system. Designed to provide precise RPM control and extensive tuning flexibility, the adjustable weights allow riders to fine-tune clutch calibration while maximizing the performance potential of the Straightline Single Pipe. The result is a sled that accelerates harder, responds quicker, and maintains optimal RPM throughout the operating range.\u003c\/p\u003e\n\u003cp\u003eThe kit also includes a custom-designed helix specifically developed for the power characteristics of the Polaris 850 equipped with the Straightline Single Pipe exhaust system.
