Ultra Series Valves are heat-treated using a proprietary process for extraordinary strength and durability. Chromium Nitride coating is deposited on each valve using physical vapor deposition (PVD) process. This coating significantly improves wear and heat resistance, creating conditions for more durability and long term usage. Chromium Nitride coating is a remarkable solution as it improves the friction coefficient between the valve's stem and valve guide; a necessity for engine components that demand resistance to high heat level environments.
