About This Product
If you are looking to squeeze more performance out of a classic Knucklehead, these Kibblewhite Black Diamond intake valves are a top-tier choice. This is a standard size replacement but features an oversized 1.940-inch head diameter for improved flow. Manufactured in the USA from one-piece stainless steel forgings, these valves receive a black nitrided finish for superior wear resistance and reduced friction. With a 0.3765-inch stem diameter and an overall length of 3.590 inches, they are designed for 1936 through 1947 Knucklehead models. KPMI uses advanced CNC and 3D modeling to ensure these components meet the highest performance standards for vintage restorations.
Manufacturer part number: 20-20414.
