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 performance consistency.
To optimize engine efficiency, the piston walls feature a nonabrasive coating that significantly reduces heat and friction. This surface treatment not only contributes to added horsepower but also greatly extends the overall lifespan of the piston, providing a durable solution for riders seeking reliable power delivery and long-term component integrity.
