This Straightline Performance clutch kit is engineered for Arctic Cat Catalyst 858 snowmobiles ridden off-trail between 0 and 3,000 feet, where boondocking demands instant, repeatable clutch response. It fits Catalyst 858 models from 2025 through 2027, so you can dial in the power delivery of a current-generation mountain sled without guesswork.

Each kit ships as a complete, sled-specific package weighing 5 lbs and measuring 11 x 9 x 6 inches, with fitment guaranteed for the listed Arctic Cat applications. Straightline Performance backs the kit with in-house expert support and an easy return policy, and it is available for pre-order ahead of its January 10, 2027 release.
