Vehicle Information
Arctic Cat Jag AFS 440 Snowmobile (1989-1993)
The Arctic Cat Jag AFS 440, produced from 1989 to 1993, was a popular snowmobile known for its reliable 431cc (often called 440cc) fan-cooled Suzuki two-stroke engine. This model was positioned as a versatile option, offering a smooth ride thanks to its Arctic Front Suspension (AFS). Throughout its production run from 1989 to 1993, the core engine remained consistent, with no significant mid-cycle generation changes or major engine overhauls. Variations primarily involved different trim levels, such as "Longtrack" models with longer tracks, and some versions like the 1993 Jag AFS LT 2 Speed, which featured a 2-speed dropcase assembly, indicating drivetrain modifications rather than engine changes.
