WSM Piston Kit - Sea-Doo - +.5 mm 010-815-05K

Stock pistons are a compromise between cost and performance—but your Sea-Doo engine deserves better. WSM Piston Kits deliver OEM-equivalent quality with measurable gains in durability and power through advanced materials and precision engineering. Whether you're rebuilding after a season or upgrading for increased displacement, this kit gives you the reliability of factory components with proven performance enhancements.

The MOS2 coating on the piston skirts is the key differentiator here. This molybdenum disulfide layer actively reduces friction and draws heat away from the combustion chamber, lowering operating temperatures and extending component life. Combined with specially hardened ring grooves and an improved E-clip design, you get a complete package that resists wear and maintains ring seal integrity under sustained high-RPM operation.
