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
Can-Am Defender HD8 Side-by-Side (2016-2021)
The Can-Am Defender HD8, produced from 2016 to 2021, is a robust utility vehicle powered by a 799.9 cc (often rounded to 800cc) Rotax V-Twin engine, consistently delivering 50 horsepower. This liquid-cooled, electronically fuel-injected (iTC) engine remained constant throughout this period, offering reliable performance for work and recreation. It was available in several trims, including base, DPS (Dynamic Power Steering), and XT models. While the HD8 engine maintained its core specifications without major displacement or horsepower changes between 2016 and 2021, the platform did see notable enhancements. For instance, the 2021 model benefited from a 5% lighter and 30% more rigid structure, improving its toughness and cargo capabilities. That year also introduced advanced drive modes such as Turf mode, 2WD, 4WD with Visco-Lok QE auto-locking front differential, and Electronic Hill Descent Control. Dynamic Power Steering (DPS) was a common feature on many trims. FAQ:
