For the extreme â€œhardcoreâ€ performance riders, Arctic Cat offers the legendary Sno Pro package (which feature Fox Float ski shocks, 2-in. diameter IFP rear arm shocks, more aggressive suspension calibration and taller 1.375-in. track lugs). Choose between F6, F8 and F1000 engines with standard features like Infinite Rider Positioning System (IRP), a low racy windshield to enhance the sexy curves of the snowmobile and standard ACT direct drive with push button reverse and roomy rear storage compartment. Not quite as close to a 440 Sno Pro as before, but still capable to kick some ass.
