KIBBLEWHITE - 20-20925 - Nitrided Valve - '99-'04 Harley-Davidson Electra Glide Ultra Classic FLHTCU, Electra Glide Standard EFI FLHTI
For '99-'04 Harley-Davidson engines, 20-20925 pairs a one-piece stainless-steel, stellite-tipped valve with Kibblewhite's nitriding treatment, a .002-inch deep hardening process that outperforms hard chrome or nickel plating on wear and corrosion resistance while keeping friction low. Its lightweight profile is shaped for efficient flow, and it's compatible with both leaded and unleaded fuel, a detail that matters on older engines still running pump gas blends. Made in the USA.
