A Powerful Mountain Sled with ALPHA ONE Single-Beam Rear Suspension

The ultimate Mountain Cat features bold styling and bold moves, with ALPHA ONE™ Single-Beam Rear Suspension and fully-adjustable FOX® FLOAT 3 QS3 shocks.


  • ALPHA ONE SINGLE-BEAM REAR SUSPENSION: Our single-beam rear suspension unlocks more maneuverability than any mountain snowmobile in history. Up here, there's only one alpha. See video link for additional details.
  • FOX® FLOAT QS3 SHOCKS: ALPHA ONE suspension is easily adjustable for ride and intensity with FOX FLOAT shocks: from the three-position QS3 on the ski and front arm, to a semi-locking QSL on the rear, you get easy adjustability for maximum deep-snow performance.
  • 8000 SERIES C-TEC2 ENGINE: New for 2020, the next generation 8000 Series C-TEC2 engine delivers a new level of clean Arctic Cat 2-stroke engine performance and technology. This new 794 cc C-TEC2 twin features include new cylinders, pistons, combustion chamber, flywheel and fuel rail; new fuel calibration strategy and Arctic Power Valve system with 3-stage control of the auxiliary exhaust ports via side valves; ECM-controlled electronic oil pump; batteryless EFI; Exhaust Pop Temperature Sensor (EPTS); knock sensor; engine reverse technology. This advanced new technology designed by Arctic Cat and built in St. Cloud, MN delivers ultra-clean, more responsive performance, enhanced power in the 165 hp class of engines, precision oil injection, precision oil injection and exceedingly robust and lightweight design.
  • AMS FRONT SUSPENSION: Arctic Mountain Suspension is tailor-made to maneuver in deep snow. The lightweight, forged-aluminum spindles sit at a 27 degree spindle caster angle, providing optimal ski camber for off-trail cornering and more predictable counter-steering when side-hilling. They’re built to reduce drag, while the dual-phase alloy-steel A-arms are lightweight and durable.
  • PUSH-BUTTON ELECTRIC START: A push of the handlebar-mounted button is all it takes for the convenience of electric start.
  • POWER CLAW TRACK: Power Claw Track is built lightweight, with a single-ply design and a 3.0-inch pitch — all so you can master deep snow runs. Its stagger-set, curved-forward paddle towers won't fold over or take a set, and Attack 20 paddles let you float over the deep stuff.
  • GOGGLE HOLDER: Mounted right in the dash for quick access, this integrated goggle holder keeps a key piece of gear safe and sound.
  • LED HEADLIGHT: Ride until the sun goes down — then keep riding, with this premium LED headlight for night riding.
  • ADJUSTABLE 35.5-37.5 IN. SKI STANCE: Easily adjust your ski stance in seconds — keep it wide for the trails or narrow through the trees.
