2026 Arctic Cat M 858 Sno Pro ALPHA ONE
Built for Deep Snow and Technical Mountain Riding
The 2026 Arctic Cat M 858 Sno Pro ALPHA ONE is built for serious mountain riders looking for exceptional power, agility and control in deep snow and technical terrain. Powered by Arctic Cat’s 858cc C-TEC2 two-stroke engine and built on the lightweight CATALYST chassis, this mountain sled features a 154-inch PowerClaw track that delivers excellent traction and flotation for steep climbs, deep powder and challenging BC backcountry riding.
At the heart of the M 858 is Arctic Cat’s ALPHA ONE mono-rail rear suspension. Its unique single-beam design creates a central pivot point under the track, allowing the sled to respond quickly to rider input. The result is exceptional maneuverability when carving, side-hilling and working through deep snow.
AC5S shocks, AWS 36 front suspension and 7-inch G2 ProClimb mountain skis complete a mountain-focused package designed to keep the sled responsive and predictable when the terrain gets technical.
