About this product
Upgrade your engine's performance with the Kibblewhite Black Diamond™ Engine Valve. These valves are engineered for superior flow, durability, and wear resistance, ensuring your engine operates at its peak potential. Made in the USA, these valves represent the pinnacle of quality and performance.
Description
The Kibblewhite Black Diamond™ valves are CNC machined from one-piece forgings of EV8 Stainless Steel, providing exceptional strength and lightweight performance. The optimized profiles deliver excellent flow characteristics, enhancing your engine's power and efficiency. A special German infusion process penetrates the valve to a depth of 0.002", with a surface build-up of 0.0002", significantly improving wear properties, reducing friction, and offering superior corrosion and wear resistance compared to chrome and nickel electrolysis plating. Each valve is designed using Finite Element Analysis (F.E.A) software, and profiles are rigorously tested on a computerized flow bench to ensure optimal performance. The stems are coated with black nitroneg for enhanced durability and reduced friction. Upgrade to Kibblewhite Black Diamond valves for unmatched reliability and performance.
