About this product
Upgrade your engine's performance with the Kibblewhite Black Diamond™ Engine Valve. This valve is engineered for superior flow, durability, and resistance to wear, ensuring optimal engine function and longevity. Made in the USA with premium materials and advanced manufacturing techniques, this valve is a top choice for enthusiasts and professionals alike.
Description
The Kibblewhite Black Diamond™ Engine Valve is CNC machined from a one-piece forging of EV8 Stainless Steel, providing exceptional strength and reduced weight. Its meticulously engineered profile enhances flow characteristics, optimizing engine performance. A special German infusion process penetrates the valve to a depth of 0.002", with a surface buildup of 0.0002", significantly improving wear properties, reducing friction, and offering superior corrosion resistance compared to traditional chrome and nickel electrolysis plating. Designed using Finite Element Analysis (F.E.A) software and tested on a computerized flow bench, each valve guarantees precision and performance. The stem is coated with black nitroneg for added durability and smooth operation. Whether you're rebuilding an engine or upgrading for performance, the Kibblewhite Black Diamond™ Engine Valve delivers unmatched reliability and power.
