Kibblewhite 80-80435 Black Diamond Exhaust Valve 34mm Oversize

The Kibblewhite 80-80435 Black Diamond exhaust valve delivers premium valvetrain performance with advanced materials and precision engineering. This 34mm oversize valve is CNC-machined from a one-piece forging of EV8 stainless steel, providing exceptional strength and durability for high-performance applications.

Advanced Surface Treatment:

Each valve undergoes a proprietary German impregnation process that penetrates .002 inches deep with a .0002 inch surface buildup. This specialized multi-stage treatment creates a friction-reducing coating that offers superior wear and corrosion resistance compared to traditional chrome or nickel electroplating. The subsequent oxidizing and polishing process produces an ultra-smooth surface finish that minimizes valve guide wear while eliminating the risk of flaking or debris that can cause valve seizure.

Key Features:

• 34mm oversize diameter for improved flow characteristics
• One-piece EV8 stainless steel forging for maximum strength
• Black Diamond surface treatment for reduced friction and enhanced durability
• Designed using Finite Element Analysis for optimal stress distribution
• Flow-tested on computerized bench for proven performance
• Lightweight construction reduces valvetrain mass
• Non-flaking surface treatment protects valve guides

Engineered for racers and performance enthusiasts who demand the ultimate in valvetrain reliability and efficiency, this valve combines cutting-edge metallurgy with precision manufacturing to deliver measurable performance gains.
