About this product
Upgrade your engine's performance and reliability with the Kibblewhite Nitrided Valve. This high-quality valve is engineered for superior wear resistance, reduced friction, and optimal flow characteristics. Experience the benefits of enhanced durability and performance in your engine.
Description
The Kibblewhite Nitrided Valve is constructed from one-piece stainless steel and features a stellite tip, ensuring exceptional durability and longevity. A specialized nitriding process, with a depth of 0.002" and a surface buildup of 0.0002", fortifies the valve to improve wear properties and minimize friction. This process offers superior corrosion resistance compared to hard chromium and electrolysis nickel-plating. The lightweight design and optimized profile provide excellent flow characteristics, maximizing engine performance. Compatible with both leaded and unleaded fuels, this valve can be used with cast iron and bronze-type guides, allowing for tight tolerances to enhance oil control and heat dissipation. Proudly made in the USA, this valve is engineered to meet the demands of high-performance engines.
