The Black Diamond™ Valve from Kibblewhite is a one-piece valve designed for Vintage/Classic and Road/Touring engines where longevity and reliability go hand in hand with demanding riding. Made from nitrided stainless steel and featuring a Stellite tip, it benefits from a special nitriding treatment (depth 0.002" and surface layer 0.0002") to enhance wear resistance and reduce friction without compromising corrosion resistance.
Lightweight and streamlined for excellent gas flow, this valve is particularly suited for the Harley Davidson cylinder heads listed below, as well as for any restoration or preparation requiring durable and precise parts.
