This clutch kit is the ultimate kit for the Skidoo 850 model. It offers awesome belt grip, hard pulling acceleration, lighting fast backshifting, totally eliminates belt slip, much cooler belt temps, and adjustability. After years of riding and testing, Team Reeds supplies OEM primary and secondary springs that have stood the test of time, ensuring that you have long-lasting products. After hours of riding, the springs have been removed and retested, showing minimal sag of up to seven pounds, while aftermarket springs typically have up to twenty-five pounds of sag along with the spring rate, maintaining their tensile strength.

Several years of testing and evolution have brought us to this setup.

Full weight install instructions are included.

Team Reeds recommends purchasing the spring cup and Reeds Extreme rollers.
