Black Diamond Exhaust Valve

These materials have proven heat and corrosion resistance properties. Each valve is designed using Finite Element Analysis software, and profiles are tested on our computerized flow bench. Strict attention is paid to the surface preparation of the valves, and the purity of the chrome is closely monitored. A 360 degree anode is used to produce the highest possible grade of hard chrome finish. White Diamond? Valves are light, strong, one piece forgings with profiles that provide excellent flow characteristics.
