Description
Bred from a rich history of experienced belt builders, the Dayco XTX belt is specifically engineered to maximize the performance of the most extreme, high horsepower snowmobiles. Beating the competition on the race course is just one of many aspects that sets the XTX belt apart from its competition. Specially formulated high temperature Polymer along with the highest level of engineered reinforcement proves to perform better in belt operating temperature and efficiency than leading competitors. Its innovative break-through design of deeper cogs on top and rounded cogs on the bottom yield the advantages of ultimate flexibility and longer belt life while being a better alternative to the original equipment belt.

Vehicle Information
Polaris IQ 800 Snowmobile (2007-2010)
The Polaris IQ 800, a high-performance snowmobile, was introduced in 2008 and produced until 2010. While the IQ chassis was available in 2007 with other engine sizes, the 800cc two-stroke model specifically debuted in 2008. It was powered by a 795cc liquid-cooled, two-stroke Liberty 800 HO Cleanfire4™ engine, known for its strong performance. This model offered various trims, including performance, crossover, and deep snow variants like the Dragon SP and RMK. Throughout its production, the IQ 800 saw notable refinements. The 2008 model introduced the new 795cc CleanFire engine. In 2009, Polaris addressed initial piston scoring issues with revised pistons and fuel mapping, and the Dragon SP trim received significant upgrades including weight reduction and enhanced suspension components. For 2010, the P2 driven clutch became standard across the lineup, improving durability and belt temperatures, alongside a new lightweight front bumper for the IQ 800 models. Q: Is this product compatible with my 2007 Polaris IQ 800?
A: The Polaris IQ 800 (800cc two-stroke) was produced from 2008 to 2010. Please use our year/model selector to ensure compatibility with your specific Polaris IQ snowmobile.
