Vehicle Information
Arctic Cat Super Jag 440 Snowmobile (1987-1992)
The Arctic Cat Super Jag 440, produced from 1987 to 1992, was a popular snowmobile renowned for its reliability and utility. Throughout these years, it consistently featured a robust 431cc fan-cooled Suzuki twin-cylinder engine. While the core engine design remained unchanged, the Super Jag 440 saw significant enhancements during its production run. In 1991, it was notably equipped with an extra-long track for improved deep-snow flotation, along with conveniences like reverse gear and hand warmers. The 1992 models introduced a "2 Speed Dropcase Assembly" and an "Articulating Skid Frame," representing a notable evolution in its drivetrain and suspension for enhanced versatility and ride quality.
