Material Options & Construction:

• Stainless Steel (EV8 / 21-4N Alloy): One-piece forged construction for superior strength and long-term reliability. Supertech primarily uses EV8 (21-4N) stainless alloy for both intake and exhaust valves, with additional alloys and heat treatments available for specialized applications.
• Inconel 751 Nickel-Base Alloy: Used for exhaust valves subjected to extreme heat, making it the preferred choice for turbocharged and supercharged engine builds where standard materials fall short.

Protective Coating Technologies:

• Chrome Coating: A widely used finish in performance valve applications, providing a hard, wear-resistant surface layer.
• Black Nitride Treatment: A hardening process that produces a smoother surface finish than chrome, resulting in reduced friction between the valve stem and guide for improved durability and performance.

Each Supertech valve is manufactured to exacting tolerances, ensuring consistent performance whether used in naturally aspirated, turbocharged, or supercharged applications. Note: Valves are sold individually (per valve). Please order the total quantity needed for your application.
