Description
If you’re running a Polaris Ultra 1997-1998 at the limit, your original pistons won’t cut it. Wiseco’s high-silicone forged pistons are engineered specifically for 2-cycle engines, delivering the strength and thermal stability needed to handle extreme conditions without sacrificing efficiency. This complete kit eliminates guesswork—you get pistons, rings, wrist pins, circlips, and gaskets all matched and ready to install.
Wiseco pistons are known for reduced thermal expansion and superior durability under sustained high-RPM operation. The high-silicone bar stock construction resists wear and maintains tight tolerances, critical for maintaining compression and power delivery in demanding applications. Installing this kit means you’re not just replacing worn parts—you’re upgrading to components designed for performance.
