WSM Piston Kit - Sea-Doo 800 - Standard 010-818K

Sea-Doo 800 engines demand precision-engineered internals to handle sustained high-RPM performance, and OEM pistons often fall short in durability under aggressive use. The WSM Piston Kit delivers OEM-equivalent quality with meaningful upgrades—specifically, an advanced MOS2 coating on the skirts that actively reduces friction and heat while enhancing ring groove strength. This kit gives you the reliability to push your engine harder without sacrificing longevity.

Each kit is engineered as a complete system: you get the piston, rings, wrist pin, and improved E-clips all matched for optimal fitment. Order one kit per cylinder, and if you need additional rings down the line, they're available separately to keep your engine running peak performance.
