Hit Hard. Hold the Line.

If you ride deep powder, you need a snowmobile that’s built to a higher standard. With the ultra-agile CATALYST™ platform and your choice of ALPHA ONE® mono-rail or twin-rail suspension, this lineup floats, climbs and carves with purpose.

Features may include:

Peak Performance Unlocked
  • CATALYST CHASSIS

The revolutionary CATALYST platform has been built from the ground up to optimize every aspect of your ride, so much so that you’ll feel at one with the sled. With enhanced ergonomics, a lower center of gravity, our exclusive laydown engine design, specially calibrated suspension and more, this changes everything.

Purpose-Built Power
  • 858 ENGINE

Push the limits with a strong, responsive output across the full RPM range with a consistent pull you can feel. The 858 two-stroke EFI engine is designed for seamless integration with the Arctic Cat CATALYST platform. Patented exhaust valves and a sealed intake system maximize airflow and throttle response, while a purpose-built design reduces weight. All resulting in a compact, durable package built to perform season after season.

Keep Yourself Planted
  • TWIN RAIL SUSPENSION

The twin rail suspension is built for one thing: carving and climbing with control. With two rails, it delivers a solid, predictable feel that keeps the track straight and the power locked in — even when the hill gets rutted, windblown or near vertical. Compared to single rail setups, it’s less flickable but more planted — perfect for riders who’d rather hold the line than play around it.

OPTIMIZED FOR DEEP SNOW
  • AWS 36 FRONT SUSPENSION

The AWS 36 Front Suspension was designed specifically with the M 858 in mind. With lightweight spindles and precision engineered geometry, this suspension system optimizes your performance in deep snow.

ULTIMATE ADJUSTABILITY
  • AC5S SHOCKS

Meet our anything-but-stock shocks. AC5S ski, front and rear track shocks are designed and calibrated at Arctic Cat for Sno Pro® sleds and feature a unique color scheme. The 5-position adjustment with adjustable spring preload gives you even more flexibility to finetune your ride.

INCREASED DURABILITY
  • ARCTIC CAT MOUNTAIN BELT DRIVE

The CATALYST platform utilizes Arctic Cat's belt drive system rather than a chain drive. This allows for enhanced durability and fewer parts in the system. The adjustable center distance allows for multiple ratio options and makes servicing simple. Additionally, the track included with the AC Mountain Belt Drive ensures that the sled gets up on the snow quicker, avoiding trenching issues.

UNPRECEDENTED TRACTION
  • POWERCLAW TRACK

Unlock the backcountry with PowerClaw™, a lightweight track that delivers the ultimate deep snow traction and performance. The staggered, forward curving paddle tower design won’t fold over, allowing you to float over the deepest snow. Available in 146-in and 154-in with 2.6-in lugs.

EASIER STEERING
  • G2 PROCLIMB SKIS

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.
