Supertech Engine Valves are engineered for high-performance street and racing applications, delivering exceptional strength, heat resistance, and precise fit.
Production begins with a one-piece forging, where the head is formed under a slow two-step process to maintain optimal material grain flow.
Each valve undergoes multiple CNC machining steps, stress-relieving heat treatments, and either nitride hardening or application-specific coatings.
