The BoonDocker High Energy™ Clutch Kit for Polaris AXYS 850 (Patriot) provides the best off-the-line throttle response, excellent midrange, and impressive top-end performance. This kit includes the revolutionary BoonDocker weights for the best performance in any category.

  • Rippier on the bottom end
  • Pulls harder through the mid-range
  • Higher top speeds
  • 30-day guarantee

For the trail rider, the weekend warrior, the meadow masher, the racer, or the snowmobile professional that wants the best performing clutch system for their P-85 clutch, the BoonDocker High Energy™ Clutch Kit for Polaris 850 will produce performance you can feel and performance that won't be beat.

So, go ahead and line 'em up. We guarantee the performance and value of our BoonDocker clutch kits with a 30-day No-Questions-Asked Guarantee. Who else in the industry makes a claim like that?

The EASIEST way to find what weight you need is to find the mass of your current 10-series weight and subtract 7grams (the weight of the #10 capsule). For example, if you are running 10-64's, then the appropriate base weight is 64g-7g=57g.

Note: Some vehicles break springs faster than others. Springs and belts are not returnable or refundable. There is no "lifespan" guarantee on springs or belts.
