Kibblewhite KPM-20-21062K White Diamond 1.0mm Oversize Exhaust Valve for Harley-Davidson Milwaukee-Eight 17-Up High Flow

We fully CNC machine our White Diamond® Valves from a one-piece forging of either EV8 Stainless Steel or Inconel-751. 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. 

Inconel® is classified as a “Super Alloy”, meaning that it is designed to survive under the most extreme temperatures and pressures where other valves will begin to burn, corrode, or completely fail. This is the material of choice for high output engines running turbos, superchargers, nitromethane, or nitrous.
