Engineered for the rigours of V-Twin operation, these Kibblewhite High Chrome valve seats are machined from solid bar stock rather than using powder metal processes. The inclusion of 18-22% chromium and 1-2% nickel creates a seat that resists deformation and wear, even when subjected to the high temperatures of a Harley-Davidson combustion chamber. These seats are compatible with various fuel types, including leaded, unleaded, and alcohol-based fuels like ethanol. The solid bar stock construction ensures a uniform material density, which translates to better heat dissipation and longevity. Whether performing a routine valve job or a complete head restoration, these Kibblewhite seats provide the reliable foundation necessary for a long-lasting engine build.
