About this product
Kibblewhite Black Diamond™ Engine Valves are the pinnacle of performance and durability. These exhaust valves are engineered for enthusiasts and professionals who demand the best in valve technology. Experience improved wear resistance and superior flow characteristics with valves crafted in the USA.
Description
The Kibblewhite Black Diamond™ valves are CNC machined from one-piece forgings of EV8 stainless steel, ensuring lightweight strength and exceptional reliability. The valve profiles are designed using Finite Element Analysis (F.E.A) software and tested on a computerized flow bench to optimize flow characteristics. A special German infusion process penetrates the valve to a depth of 0.002", with a surface build-up of 0.0002", drastically improving wear properties and reducing friction. This advanced treatment provides corrosion and wear resistance far exceeding that of conventional chrome and nickel electrolysis plating. The stems are coated with black nitroneg for enhanced durability and reduced friction. Upgrade to Kibblewhite Black Diamond™ valves for unparalleled performance and longevity.
