The WSM Complete Top End Kit features Platinum Series pistons constructed from high-strength hardened aluminum, a material selection specifically engineered to prevent skirt and ring groove breakage. By adhering to exact OEM specifications, this kit ensures precise fitment and structural integrity, providing a reliable foundation for high-performance engine builds.
To optimize thermal management and mechanical efficiency, the piston walls are finished with a nonabrasive coating. This treatment significantly reduces heat and friction within the cylinder, contributing to increased horsepower output while greatly extending the overall service life of the piston.
