Stage 1 SNYPR Clutch Kit for Polaris Patriot 850 (Long Track / Mountain Sleds) // SKU: 06-37-300-M

SKU: 06-37-300-M

Primary Application: Polaris RMK, PRO-RMK, Khaos, SKS, and Switchback Assault 850 models equipped with 2.0" or deeper lug tracks.

Unlock explosive deep-snow throttle snap and hold peak horsepower RPM in the backcountry with the Bikeman Performance Stage 1 SNYPR Long Track / Mountain Clutch Kit for the Polaris Patriot 850. Deep powder and steep technical terrain place heavy drag on your drivetrain, causing factory clutching to bog or fade RPM on long ascents. This package re-engineers your clutching foundation to keep your 850 locked directly in its peak powerband.

By pairing our hyper-tunable SNYPR magnetic adjustable primary weights with high-tensile 140-330 primary and 160-260 secondary springs, plus our Smooth Shift Primary Teflon Washers, this kit eliminates belt slip and prevents primary spring binding. The result is instant track spin when hopping on the throttle in tight technical trees and sustained, hard-pulling climbing power.

Key Performance Features

• Instant Deep-Snow Throttle Snap: Delivers immediate power to the track, eliminating low-end lag and trenching when carving or sidehilling.
• Holds Peak Mountain RPM: High-rate mountain springs maintain strong belt pinch to prevent RPM sag under extreme snow drag and steep incline resistance.
• On-The-Fly Magnetic Tuning: Easily adjust base mass through the clutch guard using magnets, set screws, and tungsten slugs to adapt to elevation changes or exhaust modifications.
• Smooth Shift Primary Friction Control: Includes Smooth Shift Primary Teflon Washers to eliminate primary spring bind and ensure smooth, consistent shift cycling.
• Direct Bolt-On Mountain Performance: Calibrated specifically to work with your factory secondary helix—making it the ultimate high-value clutching upgrade for backcountry riders.
