This Straightline Performance clutch kit is purpose-built for the Polaris Matryx RMK Boost, delivering the immediate throttle response and aggressive backshift that deep-snow boondocking demands. The package pairs adjustable P22 clutch weights with a custom-machined helix and two performance-calibrated springs, all tuned to work together as a complete system for elevations from sea level to 3,000 feet.

The adjustable weight system lets you fine-tune RPM for changing snow conditions, riding styles, and machine setups, while the helix profile sharpens shift characteristics and power transfer. The result is stronger pull, quicker acceleration, and more precise control when carving sidehills, threading tight timber, or climbing technical features.
