Description

Piston Kit – 80.40 mm – Yamaha

The WSM Piston Kit for Yamaha, part number 010-829-05PK, offers high-quality construction that meets or exceeds OEM standards, ensuring reliable performance and durability. Designed with a nonabrasive, MoS2 (Molybdenum Disulfide) coating, these pistons significantly reduce heat and friction during operation, which enhances power output and extends engine longevity. The MoS2 coating facilitates heat dissipation by drawing heat through piston walls and out the bottom, contributing to more efficient cooling and smoother performance. The pistons feature specially hardened tops that add strength to the ring grooves, preventing wear and maintaining optimal sealing for consistent compression. An improved E-clip design simplifies installation and improves security, reducing the risk of component failure. This kit is ideal for replacing worn or damaged pistons in Yamaha engines, providing a reliable upgrade that enhances engine efficiency and lifespan. Suitable for applications requiring an 80.40 mm piston diameter, this kit delivers precision fitment and robust performance for demanding marine or recreational engine use.
