Description
When you’re pushing your Polaris to the limit, stock pistons become your bottleneck—they’re simply not engineered for sustained high-performance demands. The WSM Piston Kit delivers OEM-equivalent quality with critical performance upgrades: a proprietary MOS2 coating that actively reduces friction and heat while strengthening ring grooves against detonation. This is the foundation of a reliable, powerful build.
Order one kit per cylinder and experience measurable gains in efficiency and durability without compromise.
