Speedwerx ProCharger Supercharger Kit  // 2019-2022 Polaris PRO RMK AXYS 850 (does not fit Matryx chassis)

For years Speedwerx has been leading the industry in snowmobile performance and this product takes that to a completely new level. Since 2010 Speedwerx is the only company to successfully put a complete 2-stroke snowmobile supercharger kit on the market. Since then we won the first and only X-Games Hillcross Gold Medal on a boosted sled, several riders have piloted Speedwerx Supercharger powered machines to multiple RMSHA class wins, and Garth Kaufman won a RMSHA National championship in 2017 piloting a Supercharged M6000 C-TEC2 machine the 600 Mod class. Using that same race and championship winning technology, we have developed a complete pump gas Supercharger kit for high elevation use on the 2019-2021 Polaris PRO-RMK 850 with the new 850 Patriot engine- it makes 200+ hp on premium pump gas at 4500'+ elevation. We utilize a top of the line supercharger head unit from ProCharger- the industry leader in superchargers. The kit comes complete with everything needed to complete the build- fuel controller, injectors, plug and play wiring, clutching, exhaust, etc. and it comes standard with a self-contained water-to-air intercooler system, and a cogged pulley and belt setup for more consistent performance- you can expect to see charge temps of only 60-80° on typical mountain riding days! The performance gained with this kit will blow you away for a pull and go pump gas machine- not only is the performance great, but the quality of parts and service is unmatched as well!
