About this product
About this product
The Kibblewhite White Diamond® Engine Valve delivers exceptional performance and durability for your high-performance engine. Manufactured in the USA with meticulous attention to detail, this valve ensures optimal gas flow and reliable operation under demanding conditions.
Description
Kibblewhite White Diamond® valves are engineered to withstand the rigors of high-performance engines. Each valve is CNC machined from a one-piece forging of premium EV8 Stainless Steel, providing superior strength and heat resistance. The valve undergoes a specialized electroplating process, utilizing a 360º anode to apply an even coating of the highest grade hard chrome finish. This protective layer minimizes friction, enhances wear resistance, and extends the valve's lifespan. The 20° tulip angle promotes efficient airflow, contributing to improved engine performance. Whether you're building a race engine or upgrading your existing powerplant, Kibblewhite White Diamond valves provide the reliability and performance you demand. Designed for intake applications.
