Vehicle Information
Polaris Rush Pro 850 Snowmobile (2019-2020)
The Polaris Rush Pro 850, available for the 2019 and 2020 model years, is a high-performance snowmobile built on the proven AXYS chassis. It features the powerful 850 Patriot engine, an 840 cc 2-cylinder unit generally rated for approximately 165-173 horsepower. The introduction of the 850 Patriot engine in 2019 marked a new engine generation for Polaris snowmobiles. Between 2019 and 2020, there were no major mid-cycle generation changes to the Rush Pro 850, with both model years utilizing the same AXYS platform. A "2019.5 flash" update improved power output for the 2019 models, and 2020 models continued with similar performance. Trims offered included the 850 RUSH PRO-S and 850 RUSH PRO-S SC SELECT for both years. The 850 RUSH XCR was available in 2019 but was not listed as a Rush trim for 2020, being primarily associated with other Polaris models that year. Q: How do I know which Polaris Rush Pro 850 model year I have?
A: Please use the year and edition selector at the top of this page to ensure you find parts specific to your snowmobile.
