Piston Kit – 75.50 mm – Polaris

The WSM Piston Kit, part number 50-310-07PK, is designed for optimal performance and durability in Polaris engines. Crafted with high-quality materials, this piston kit features a nonabrasive MoS2 (Molybdenum Disulfide) coating on the skirts, which helps reduce heat and friction during operation, resulting in increased power output and extended engine life. The MoS2 coating actively draws heat away through the piston walls and out the bottom, enhancing cooling efficiency and preventing overheating under demanding conditions. Its specially hardened tops add strength to the ring grooves, ensuring reliable performance and resistance to wear over time. The kit also incorporates an improved E-clip design, providing secure and easy installation, and is intended for use with one piston per cylinder to maximize engine efficiency. Engineered to meet or exceed OEM standards, this piston kit is a dependable choice for restoring or upgrading your Polaris engine’s performance and longevity.
