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 Trail 550 Snowmobile (2004-2010)
The Polaris Trail 550, a popular snowmobile model from 2004 to 2010, was known for its reliable 544cc, 2-stroke, fan-cooled, twin-cylinder engine, typically producing 60 horsepower. This engine platform remained consistent throughout the production run, forming the core of various trims.
While the engine displacement was stable, Polaris introduced several key upgrades. In 2004, the 550 fan engine received a new pipe and digital ignition, leading to slight horsepower gains and improved fuel economy. Concurrently, the Trail RMK model transitioned to the EDGE chassis and incorporated the Altitude Compensating Carburetion System (ACCS). Further enhancements in 2006 included NiCaSil-lined cylinders for the 550 Fan engine, improving emissions and fuel efficiency, a feature that continued into 2007. Q: How do I ensure I select the correct parts for my Polaris Trail 550?
