Wossner Piston Kit 80.86mm Arctic Cat ZR 800 2001-2002 K7011DA-2

The stock piston in your Arctic Cat ZR 800 is a wear item—and when clearances open up or ring sealing degrades, you lose compression, throttle response, and fuel efficiency. The Wossner K7011DA-2 piston kit delivers OEM-grade replacement or performance upgrade with precision engineering and durable materials built to handle extreme cold and high-RPM demands. This is a bolt-on refresh that restores your sled's original power or sets the foundation for reliable upgrades down the line.

What you're getting is a complete kit with everything needed for installation—pistons, rings, and pins—so you won't be left hunting for compatible components. Wossner's reputation in motorsports is built on tight tolerances and quality control, and this kit reflects that commitment to reliability in harsh riding conditions.
