FULL DESCRIPTION
Vertex Performance Top End Piston Kit
The Vertex Top End Kit provides a complete, high-quality solution for restoring engine performance and reliability. Designed as an exact OEM replacement, this comprehensive kit includes all essential components required for a successful top-end rebuild, ensuring optimal function and seamless installation.
Each piston is engineered for durability, utilizing a gravity cast aluminum alloy with an 18% silicone content. This advanced composition creates a component that is exceptionally lightweight yet maintains high structural strength. To further enhance longevity and efficiency, the pistons feature a hi-tech molybdenum disulphide coating on the skirts to facilitate a faster break-in period, along with a nitride coating for increased overall piston life.
