Straightline Performance Polaris Matryx RMK Boost High Elevation Mountain Clutch Kit | 6,000+ ft

The most tunable and precise kit on the market for your Polaris Boost.

Comes complete with Straightline’s premier weight tuning kit that uses set screws and washers for a more precise tuning.  The kits comes complete with a very precise baseline that rarely needs to be changed.

The Straightline Performance Polaris Matryx RMK Boost High Elevation Mountain Clutch Kit was developed for riders who demand maximum performance from their turbocharged Polaris in the most demanding mountain environments.

The Patriot Boost engine delivers incredible power, but to fully utilize that power at elevations above 6,000 feet requires clutch calibration specifically engineered for high-altitude operation. Through extensive testing in real-world mountain conditions, Straightline Performance has developed a complete clutch package that maximizes power transfer, throttle response, acceleration, and deep snow performance.

At the core of the system are Straightline Performance’s premium adjustable P22 clutch weights. Unlike fixed-weight systems, these adjustable weights allow precise clutch calibration to maintain ideal engine RPM while adapting to changing snow conditions, elevation changes, riding styles, and machine modifications. This flexibility helps ensure peak performance throughout the riding season.

The package also includes a custom-machined performance helix specifically developed for the Polaris Matryx RMK Boost platform operating at higher elevations. The helix profile is designed to improve shift characteristics, maximize power transfer, and provide quick, responsive backshift in technical terrain and deep snow conditions.

Two performance-calibrated clutch springs complete the system. Carefully matched to the weight package and helix, these springs provide consistent engagement, maintain target RPM, and improve overall clutch efficiency while handling the substantial power output of the Patriot Boost engine.

Whether you’re climbing steep alpine terrain, navigating technical tree lines, sidehilling deep powder, or carving open mountain faces, this clutch kit is engineered to keep your RMK Boost operating at its full potential. Riders will experience stronger acceleration, quicker throttle response, improved belt efficiency, and more predictable performance in demanding mountain conditions.

Every component has been tested under real-world riding conditions to ensure reliability, consistency, and maximum performance. The result is a clutch package that transforms turbocharged power into usable mountain performance where it matters most.
