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
Ski-Doo MXZ 440 Snowmobile (1996-2007)
The Ski-Doo MXZ 440, produced from 1996 to 2007, was a high-performance snowmobile known for its agility and race-bred capabilities. Powered by a robust Rotax twin-cylinder engine, typically around 437-440cc, it was offered in both liquid-cooled (LC) and fan-cooled (Fan) versions. This model underwent significant evolution in its chassis and engine configurations throughout its production run, catering to both recreational riders and serious racers. The MXZ 440 saw three distinct chassis generations. It started on the S-Chassis (1996-1998), which improved suspension travel. In 1999, it transitioned to the all-new ZX Chassis (1999-2002), offering enhanced handling. A major generational shift occurred in 2003 with the introduction of the REV Chassis (2003-2007), providing an advanced rider-forward position. Engine refinements included carburetor model changes for race versions in 2001-2002 and increased compression ratios with improved carb calibrations in 2004 for better performance. Various trims like LC, Fan, ZX, X, and MXZX denoted cooling types or race-specific packages. Q: How do I know if this part fits my Ski-Doo MXZ 440?
