Speedwerx Hypershift Clutch Kit for Polaris 850 Patriot Boost RMK

These new setups absolutely rip and make these awesome sleds even more fun to ride. They work with the stock ECU flash and our Stage 2 and 3 ECU flashes. The throttle response, acceleration, backshifting and all-around drivability on these setups are great and you will not be disappointed. The turbo lag is very much improved on the stock ECU tune and with our Stage 2 or 3 tunes it's hardly noticeable. The kit comes with our new dual adjusting Ripper 10-2 Series Weights which come pre-set for your riding elevation, our industry leading H5 Alloy Primary and Secondary Springs, a Primary Spring Life Washer, two R2 Series Secondary Rollers to allow for a dual track helix, and a Billet Aluminum Lightweight Helix which is about .4 lbs lighter than stock. 

This kit works on machines with stock tunes, and Speedwerx Stage 2 and Stage 3 tunes as well. The stock tune runs at 8300 +/- 100 rpm, and the Stage 2 and 3 tunes at 8500 +/- 100 rpm.

Kit Includes:

  • Speedwerx Machined Dual Adjustable Clutch Weights (adjustments are pre-set)
  • Body and Belly Weight Adjustment Kits
  • H5 Alloy Primary and Secondary Springs
  • Speedwerx Lightweight Two Angle Helix (saves .4lbs)
  • R2 Series Bearing Grade Secondary Rollers to allow Two Angle Helix

Update 2/1/24: New and Improved Calibration with our Ripper 10-2 series weights for High Elevation applications! These new setups are much more responsive, feel much more powerful, and make the sled more playful. 

Like all of our Hypershift clutch kits, this kit gives you a huge bang for your buck.  We designed and developed a completely New, fully dual adjustable weight profile that dramatically improves the bottom end and response on this machine.

For many years, Speedwerx had worked very hard to set the bar in performance clutch kits utilizing titanium springs. The springs and clutch kits worked perfectly but the price was hard to swallow due to the rising cost of titanium. After two years of rigorous testing, we introduced the H5 Alloy springs in 2008. The H5 Alloy springs have a 30,000 to 40,000 psi higher tensile strength compared to standard chrome silicon wire springs and they won't lose rate over time, so you can get the durability and consistent performance of a titanium spring at a fraction of the cost. The H5 Alloy springs have set the new standard in performance for trail, mountain, and racing applications!

The individual components will vary depending on the application and riding elevation, but most of our performance clutch kits come with an H5 Alloy Primary Spring, a set of our Hypershift machined weights, one of our custom cut Secondary Helixes, and an H5 Alloy Secondary Spring. Some kits may also include a tip weight adjustment kit for fine tuning or a new drive belt as well. If you want a smooth, yet hard pulling holeshot, excellent back shifting and great throttle response, look no further than the Speedwerx Hypershift Clutch Kits.
