Wiseco Piston Ring Set 85mm Bore Arctic Cat ZR 900 2003-2005 3347KD

Piston ring degradation is a silent killer of engine performance—allowing blowby, reducing compression, and bleeding power. The Wiseco 3347KD ring set delivers precision-fit sealing that restores combustion efficiency and maintains consistent compression across the entire RPM band. For Arctic Cat ZR 900 owners demanding reliability through extreme conditions, this is the OEM-quality upgrade that keeps your engine performing at peak output.

Wiseco rings are engineered with proprietary materials that resist thermal expansion and wear, ensuring your engine maintains proper ring-to-groove clearances even under sustained high-load conditions. Installation is straightforward—a bolt-on upgrade requiring no custom fabrication—making this an accessible performance refresh for both professional rebuilds and serious DIY work.
