About This Product
For builders looking for a bit more flow on the exhaust side of an Ironhead, this Kibblewhite Black Diamond valve is an excellent choice. It is a standard replacement style but features an oversized 1.630-inch head diameter. The stem diameter is 0.3384 inches and the overall length is 3.510 inches. Forged from one-piece stainless steel and finished with a black nitrided coating, this valve is built to withstand the high temperatures of the exhaust port while reducing friction. It fits 1957 through 1983 Sportster models. These USA-made valves represent the pinnacle of valve train technology for vintage Harleys, offering superior performance and longevity.
Manufacturer part number: 20-4197-1.
