The Kibblewhite White Diamond® Engine Valve is designed for riders and builders who want dependable sealing, durability and consistency in demanding engine conditions. Each valve is CNC-machined from a one-piece forging (EV8 stainless steel or Inconel-751 depending on application) to deliver stable strength and precision where it matters most in the valvetrain.
To improve wear resistance and longevity, White Diamond™ valves are electroplated using a 360° anode process, creating an even coat of high-grade hard chrome across the valve surface. This helps the valve stand up to heat, friction and repeated cycles—ideal for performance-focused maintenance and rebuilds.
