Take your Ski-Doo 850 or 850R Factory Turbo to the next level with the Straightline Performance Factory Turbo Clutch Kit. Designed specifically for riders operating above 6,000 feet elevation and running track lengths from 146 to 175 inches, this kit delivers increased track speed, improved backshift, and enhanced throttle response. Featuring Straightline’s adjustable P-Drive weight system, a performance-calibrated helix, and clutch springs, the kit offers greater tunability and performance than factory clutching. Updated clicker bolts are included to provide quick, precise clutch adjustments for changing riding conditions.
