The WSM Platinum Series piston kit is engineered from high-strength hardened aluminum, a material selection specifically designed to prevent skirt and ring groove breakage under demanding conditions. Each kit contains one piston, one ring set, one wrist pin, and one pair of circlips, ensuring a complete assembly package that adheres to exact OEM specifications for precise fitment and reliability.
To optimize performance and durability, the piston walls feature a nonabrasive coating that reduces heat and friction. This treatment contributes to added horsepower while significantly extending the overall life of the piston, making it a robust choice for riders seeking consistent power delivery and long-term component integrity.
