Supertech Performance uses their experience of more than 20 years in the manufacturing of racing valves, do intensive testing and work very closely with many engine builders in order to continuously improve and provide the market with the best possible product for every application. High flow rates, durability and quality are of great concern to Supertech Performance.
Stainless Steel Alloys
Made as a one piece forged valve for higher strength and reliability. We use mostly EV8 (21-4N) for intake and exhaust valves but there are other alloys that we use along with different heat treatments to manufacture valve for different applications. Other hard metal alloys may be welded to harden certain areas like the tips or seats. We use mainly two different types of coatings:
Chrome Coating
Widely used in high performance valves.
Includes a set of 8 valves
