Description

The stock drive belt on your 2019 Ski-Doo Backcountry 850 E-TEC is your direct link between engine output and track acceleration—and it's working harder than ever on high-performance builds. The Ultimax XS Drive Belt (XS821) is engineered to handle the demands of serious snowmobilers who refuse to leave power on the table, delivering superior grip, reduced slippage, and extended service life compared to OEM components.

Built with a proprietary rubber compound and double-cog design, this belt maximizes horsepower transfer while operating cooler under intense trail conditions. If you're pushing your 850 to its limits, this is the upgrade that pays dividends in reliability and performance.
