Wiseco Piston Kit for Harley M8 128ci 2017-2022 K2802

Stock pistons can't handle the demands of a high-performance M8—especially if you're running forced induction or aggressive tuning. The Wiseco K2802 delivers the durability and power gains you need with proprietary coatings and precision engineering designed specifically for the Harley M8 128ci platform. This is the upgrade serious riders choose when reliability and horsepower matter equally.

Built for both stock and Screamin' Eagle cylinder heads, this kit features Wiseco's ArmorX™ and ArmorFit™ technologies to eliminate ring flutter, reduce friction, and ensure consistent performance across thousands of miles. Whether you're tracking your bike or maximizing weekend rides, these pistons give you the confidence to push harder.
