Description
Worn or damaged piston rings are one of the fastest ways to lose compression and watch oil consumption climb—especially in a high-revving 440cc two-stroke like your Arctic Cat ZR. The Wiseco Ring Set 2618CD restores proper ring-to-bore sealing, bringing back the combustion pressure and fuel efficiency your sled lost over time. If you’re rebuilding your engine or looking to maximize performance during a top-end refresh, these rings are engineered to deliver reliable operation whether you’re trail riding or pushing hard on the ice.
