The WSM Piston Kit, designed for Polaris engines, offers reliable performance with high-quality construction that meets or exceeds OEM standards. The pistons are equipped with a nonabrasive MoS2 (Molybdenum Disulfide) coating, which reduces heat buildup and friction, resulting in improved power output and extended engine life. This coating actively draws heat through piston walls and directs it out the bottom, helping to maintain optimal operating temperatures during demanding conditions. The specially hardened tops provide added strength to the ring grooves, ensuring durability and resistance to wear over time. Additionally, the kit features an improved E-clip design that enhances assembly security and ease of maintenance. Ideal for cylinder-specific upgrades, this piston kit is recommended to be ordered one per cylinder to ensure proper fit and performance. Constructed with precision and attention to detail, the WSM 50-300-07PK piston kit is a dependable choice for enthusiasts seeking to restore or enhance their Polaris engine's power and reliability.
