About This Product
This standard size Kibblewhite Black Diamond exhaust valve is a premium replacement for 1970 through 1983 Sportster models. It features a 1.750-inch head diameter and a 0.3384-inch stem diameter, with an overall length of 3.620 inches. It is designed to replace OEM 18080-70R. Forged from one-piece stainless steel and finished with a black nitrided coating, this valve is built to handle the extreme heat of the exhaust port while maintaining its structural integrity. Manufactured in the USA, these valves are the choice of professional mechanics for their consistent quality and superior performance over stock components during a top-end rebuild.
