Featuring Straightline’s fully adjustable weight system, custom-designed low-elevation helix, and two performance-calibrated clutch springs, this package delivers stronger acceleration, improved throttle response, faster backshift, and exceptional deep snow performance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote: Straightline Performance Single Pipe exhaust system sold separately.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe Straightline Performance Polaris RMK, SKS, and Assault 850 Single Pipe Boondocking Clutch Kit was developed specifically for riders operating a Straightline Performance Single Pipe exhaust system at elevations from sea level to 3,000 feet.\u003c\/p\u003e\n\u003cp\u003eThe Straightline Performance Single Pipe enhances horsepower and improves engine efficiency throughout the powerband. To fully capitalize on those gains, clutch calibration must be tailored specifically to the modified engine characteristics. This clutch package is engineered to maximize the performance benefits of the Straightline Single Pipe while delivering exceptional deep snow control and responsiveness.\u003c\/p\u003e\n\u003cp\u003eAt the core of the system is Straightline Performance’s proven fully adjustable weight kit. Designed to provide precise RPM control and exceptional tuning flexibility, the adjustable weights allow riders to fine-tune clutch calibration while maintaining peak engine performance. The result is stronger acceleration, improved throttle response, and more efficient power transfer in deep snow conditions.\u003c\/p\u003e\n\u003cp\u003eThe package also includes a custom-designed helix developed specifically for Polaris 850 models equipped with the Straightline Performance Single Pipe and operating at lower elevations. Extensive testing in technical mountain terrain and deep powder conditions resulted in a helix profile that improves clutch efficiency, enhances shift characteristics, and delivers aggressive backshift response when immediate power is needed.\u003c\/p\u003e\n\u003cp\u003eTwo custom-calibrated clutch springs complete the package. Carefully matched to the adjustable weights and helix, these springs improve clutch engagement, maintain consistent RPM control, and maximize overall clutch performance.\u003c\/p\u003e\n\u003cp\u003eUnlike trail-focused clutch setups, this package is designed around deep snow riding and technical terrain. Riders will experience improved maneuverability, stronger low-end pull, quicker throttle response, and more predictable control when boondocking through trees, sidehilling steep terrain, or climbing technical features.\u003c\/p\u003e\n\u003cp\u003eEvery component has been tested together as a complete system to ensure reliability, consistency, and maximum performance in demanding backcountry conditions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStraightline Performance Single Pipe exhaust system is not included and must be purchased separately.\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch3\u003eFEATURES \u0026amp; BENEFITS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDesigned for Polaris RMK, SKS, and Assault 850 models\u003c\/li\u003e\n\u003cli\u003eSpecifically calibrated for Straightline Performance Single Pipe applications\u003c\/li\u003e\n\u003cli\u003eOptimized for 0-3,000 feet elevation\u003c\/li\u003e\n\u003cli\u003ePurpose-built for boondocking and backcountry riding\u003c\/li\u003e\n\u003cli\u003eIncludes Straightline Performance fully adjustable weight kit\u003c\/li\u003e\n\u003cli\u003eCustom-designed low-elevation performance helix\u003c\/li\u003e\n\u003cli\u003eIncludes two custom-calibrated clutch springs\u003c\/li\u003e\n\u003cli\u003eImproved throttle response and acceleration\u003c\/li\u003e\n\u003cli\u003eFaster and more responsive backshift\u003c\/li\u003e\n\u003cli\u003eBetter power transfer and clutch efficiency\u003c\/li\u003e\n\u003cli\u003eMaintains optimal RPM with Single Pipe-equipped machines\u003c\/li\u003e\n\u003cli\u003eEnhanced maneuverability in deep snow and technical terrain\u003c\/li\u003e\n\u003cli\u003eAdjustable weight system for changing conditions\u003c\/li\u003e\n\u003cli\u003eImproved belt performance and drivability\u003c\/li\u003e\n\u003cli\u003eExtensive real-world mountain testing\u003c\/li\u003e\n\u003cli\u003eEngineered and tested by Straightline Performance\u003c\/li\u003e\n\u003cli\u003eStraightline Performance Single Pipe sold separately\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eIMPORTANT FITMENT NOTE\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eThis clutch kit is designed specifically for Polaris RMK, SKS, and Assault 850 models equipped with a Straightline Performance Single Pipe exhaust system.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Straightline Performance Single Pipe is NOT included with this clutch kit and must be purchased separately.
