About this product
Upgrade your engine's performance and reliability with the Kibblewhite Black Diamond™ Engine Valve. Engineered for superior flow and durability, this valve is a must-have for motorcycle enthusiasts and professionals seeking to optimize their engine's capabilities.
Description
Kibblewhite Black Diamond™ valves are CNC machined from one-piece forgings of EV8 Stainless Steel, ensuring exceptional strength and lightweight performance. The valve's profile is designed to provide excellent flow characteristics, maximizing engine efficiency. A special German infusion process enhances the valve's wear properties, reducing friction and offering superior resistance to corrosion and wear compared to traditional chrome and nickel electrolysis plating. Each valve undergoes rigorous design and testing, utilizing Finite Element Analysis (F.E.A) software and computerized flow bench analysis. The stems are coated with black nitroneg for added protection and reduced friction. Made in the USA, this valve embodies quality and performance.
