794781 Valve Seat Hi Chr 2 257 X1 550 X 500

Designed for the rigours of Harley-Davidson engine operation, these Kibblewhite High Chrome valve seats are machined from solid bar stock to provide a stable and wear-resistant surface. The material composition features 18-22% chromium for heat and abrasion resistance, alongside 1-2% nickel for added toughness. This makes them an effective choice for engines running various fuel types, including ethanol-rich blends and methanol. Unlike powder metal seats, these solid units machine as a continuous chip, which is preferred by machinists for achieving exacting tolerances during installation. Kibblewhite’s focus on material science ensures these seats maintain their shape and seal under the thermal stresses common in air-cooled V-twin engines.
