Features
ALPHA ONE SINGLE-BEAM REAR SUSPENSION
Unmatched Control
ALPHA ONE Suspension is the only single-beam rear suspension in the industry, providing enhanced agility in deep snow. The lightweight, single-beam design provides nimble action, allowing riders to maneuver the sled and carve tighter circles with less effort than conventional, dual-rail snowmobiles.
ARCTIC MOUNTAIN SUSPENSION
Proven Suspension
AMS™ 37 Front Suspension is built to deliver confident performance in deep snow, combining lightweight spindles with precision-engineered suspension geometry for responsive control and maneuverability. Forged-aluminum spindles reduce drag while maintaining predictable handling in variable conditions. Paired with hydraulic twin-tube shocks and durable dual-phase alloy-steel A-arms, AMS provides smooth bump absorption and reliable performance when deep snow demands more from your sled.
MID-SIZE CHASSIS
LIGHT AND NIMBLE
The M 400 mid-sized chassis is extremely lightweight, making it agile and easy to handle, no matter your skill level. With a lightweight mountain seat and a short tank, this sled makes transferring weight while cornering effortless.
ARCTIC DRIVE SYSTEM
SMOOTH POWER DELIVERY
The lightweight, low-maintenance Arctic Cat M Belt Drive System has a CVTech Trailbloc drive clutch and CVTech Invance driven clutch to deliver power to the snow. It also provides more low-end power and throttle control, which is needed when navigating deep snow.
G2 PROCLIMB SKIS
EASIER STEERING
The lightweight G2 ProClimb™ 7-inch Mountain Ski is tapered to stay on top of the snow. The ski works in tandem with the AMS spindles for easier steering and better deep snow performance.
