About This Product
These Kibblewhite Black Diamond valves are a top-tier choice for anyone maintaining or restoring a classic 1929 to 1973 45-cubic inch Flathead, including W and G series models. Manufactured in the USA, these valves are one-piece stainless steel forgings featuring a signature black nitrided finish for superior wear resistance and reduced friction. This standard size replacement features a 1.625-inch head diameter, a 0.3395-inch stem diameter, and an overall length of 5.585 inches. KPMI uses advanced 3-D computer modelling and CNC equipment to ensure these components meet high-performance standards. Whether you are doing a stock rebuild or looking for more durability, these valves provide the precision machining your vintage Harley deserves.
