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
Kawasaki Mule PRO-FX Side-by-Side (2016-2026)
The Kawasaki Mule PRO-FX series, spanning model years 2016 to 2026, is a versatile utility vehicle designed for both work and recreation. Throughout this period, it has offered a range of configurations, including 3-passenger (PRO-FX), 3-to-6-passenger Trans Cab (PRO-FXT), and sportier variants (PRO-FXR). Engine options have included a reliable 812cc 3-cylinder gasoline engine, a more powerful 999cc 2-cylinder gasoline engine introduced in 2024, and a 993cc 3-cylinder diesel engine available in select PRO-DX/DXT models. The most significant evolution within the PRO-FX lineup occurred in 2024 with the introduction of a new 999cc liquid-cooled parallel-twin engine. This engine, offering increased horsepower and torque, powers the MULE PRO-FX 1000, PRO-FXR 1000, and PRO-FXT 1000 models. For 2025 and 2026, Kawasaki continues to offer both the original 812cc engine (e.g., PRO-FX 820) and the newer 999cc options, providing a broader choice for consumers. While not a complete platform overhaul, this represents a major powertrain update. Q: How do I ensure I select the correct parts for my Kawasaki Mule PRO-FX?
