Common questions
Which Ski-Doo models does this belt fit?
This belt fits: 2019-2026 Ski-Doo Backcountry / Backcountry X / X-RS E-TEC 850; 2020-2026 Ski-Doo Expedition SE / LE / Xtreme / SWT (E-TEC 850, ACE 900 Turbo, Turbo R); 2018-2026 Ski-Doo Freeride E-TEC 850 / 850 Turbo / Turbo R; and more (see the fitment table). This is a summary; the product description has the full model-by-model list. Check the OEM part number on your old belt.
What OEM part number does this belt replace?
It replaces Ski-Doo OEM part numbers 417300571, 417300531, 417300551. The Hunterworks part number is HW-CA850900.
How is this different from the stock Backcountry belt?
Hunterworks belts use a proprietary construction engineered for toughness and strength, with higher strength than the OEM belt. They are built for better grip, less jerky starts, and less secondary squeal.
Is this belt made in the USA?
Yes. Hunterworks belts are made in the USA. Todd, the owner, designs every Hunterworks product, and you can contact him directly with clutching questions.
How do I break in a new Hunterworks belt?
Keep it at half throttle or less for the first 30 miles and let it go through a couple of heat and cool cycles so it seats in the clutch faces. It fully limbers up over the first 100-200 miles, then ride it normally.
Is there a warranty?
Yes. Hunterworks belts carry a limited warranty. Read the Belt Warranty page linked on this product before installing, since it covers what is and isn't covered.
How do I change the belt on a Backcountry?
Remove the clutch cover, open the secondary clutch sheaves (a belt change tool makes this easier), walk the old belt off, install the new belt with the part number facing out, and reinstall the cover. Hunterworks has step-by-step videos for most machines on the Videos page and in the product description.
