Description
Engineered for superior acceleration and top speed, particularly in loose snow conditions. Put the power you have on the snow, not out under the snow flap. No matter what it's age, give your performance sled more go on the snow with a Camso high performance trail track.
Please Note
Not all tracks can be installed on all sleds without modification. The listings in the application chart fit OEM suspension, track width, length, and drive pitch only. To determine if an optional track is compatible with a particular snowmobile, you must check the bulkhead, tunnel, heat exchanger, and suspension wheel positioning for proper clearance.

Polaris Rush 850 Snowmobile (2019)
The 2019 Polaris Rush 850 is a performance snowmobile that marked the introduction of the Patriot 850 engine. This 840 cc, 2-cylinder engine was acclaimed as the most powerful and quickest-reacting two-stroke in the sport, delivering unrivaled acceleration and response. For the 2019 model year, the Rush 850 was primarily offered in PRO-S and XCR trims, exclusively available to SnowCheck program buyers. The 2019 model year was significant for the Rush 850 due to the introduction of the all-new Patriot 850 engine. This liquid-cooled 850 twin engine represented a major upgrade, designed for enhanced durability and superior performance. This new engine was a key highlight of Polaris's 2019 lineup. The Rush Pro-X models were discontinued that year, with buyers shifting towards the XCR trims. FAQ:
