SPI Clutch Kit Boondocking "Off-trail" Polaris Boost RMK 2022-

Straightline Performance Boondocking clutch kit for Polaris Matryx RMK Boost at 0–3,000 ft / approx. 0–914 m elevation. Adjustable P22 clutch weights, a low-elevation custom helix and two calibrated springs improve deep-snow acceleration, throttle response and backshift under changing load. The weight system can be fine-tuned to keep engine RPM in its effective operating range when riding technical tree lines, sidehills and powder. This low-elevation off-trail setup is distinct from a top-speed-oriented trail calibration.
