Arctic Cat 450XC 4X4 2015 Parts & Accessories

Founded in 1960 by snowmobile pioneer Edgar Heteen in Thief River Falls, Minnesota, Arctic Cat built its legacy as one of the "Big Four" snowmobile manufacturers before expanding into the all-terrain vehicle (ATV) market in 1996. Debuting with the Bearcat 454, Arctic Cat set itself apart by focusing on high ground clearance, long suspension travel, and heavy-duty utility features such as integrated front and rear SpeedRack accessory systems. Textron acquired Arctic Cat in 2017, briefly rebranding the off-road line under "Textron Off-Road" before restoring the iconic Arctic Cat brand name in 2019. Today, Arctic Cat continues to manufacture rugged utility, mid-size, and two-up touring ATVs alongside its Wildcat side-by-side series.
