About this product
Upgrade your engine's performance and reliability with the Kibblewhite Black Diamond™ Engine Valve. This high-performance valve is engineered for superior flow, wear resistance, and durability, ensuring optimal engine function and longevity.
Description
The Kibblewhite Black Diamond™ Engine Valve is CNC machined from one-piece forgings of EV8 Stainless Steel. These lightweight yet strong valves feature profiles designed for excellent flow characteristics. A special German infusion process enhances the valve's surface with a .002" deep layer and a .0002" surface build-up, dramatically improving wear properties, reducing friction, and providing exceptional resistance to corrosion and wear, surpassing 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 testing to ensure optimal performance. The valve stems are coated with black nitroneg for added protection and smooth operation. Made in the USA, these valves guarantee top-tier quality and performance for your engine.
