Skunk2 Ultra Series Valves are premium valves constructed of HNV3 martensitic steel (IN) and EV8 austenitic steel (EX) one-piece forgings. The Ultra Series Valves are designed to provide optimized airflow and ensure exceptional strength and power. They are highly resistant to oxidation and corrosion and are designed for engines that output extremely high temps! Each valve comes heat-treated using a proprietary process and then coated with Chromium Nitride using physical vapor deposition (PVD) process. This results in unparalleled structural strength and heat resistance, making the Ultra Series Valves built to last and perform. The Chromium Nitride coating has shown unbeatable results when it comes to improving the friction coefficient between the valve's stem and valve guide - a must-have for engine components that require resistance to high heat levels. If you're looking for exceptional performance, reliability, and quality, then the Ultra Series Valves are just what you need!
