2026 Arctic Cat HCX 858

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.

A NEW BREED OF POWER

858 ENGINE

The 858 two-stroke engine is designed for seamless integration into the new CATALYST platform. With an 8% increase in displacement, this engine houses an 11% increase in output over the C-TEC2 800 and weighs 4% less. It features an optimized air intake system, a new exhaust valve design for more consistent power and cleaner emissions, and an all-new crankcase for increased stroke and integrated engine mounts.

SMOOTH POWER DELIVERY

ADAPT CVT SYSTEM

With its lightweight, narrow design that increases performance and belt life, as well as the industry’s only self-adjusting clutch, the ADAPT™ CVT system provides better throttle response, smoother power delivery and a ride like no other.

UNPRECEDENTED TRACTION

Power Claw Track

Unlock the backcountry with Power Claw™, 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 or 3.0-in lugs.

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.

Keep Yourself Planted

Twin Rail Suspension

The twin rail braced suspension is built for one thing: carving and climbing with control. With two braced 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.

BRIGHTEN ANY RIDE

Asymmetrical LED Headlight

A premium LED headlight is crucial to optimize your visibility. Equipped with both high and low-beams, this headlight casts an LED light pattern with great range and width. Plus, with it's unique asymmetrical design, everyone will know that you're on an Arctic Cat.
