KIBBLEWHITE - 20-22100 - Black Diamond™ Engine Valve Kit - '48-'65 Harley-Davidson Electra Glide, Hydra Glide, Duo-Glide
When it's time to freshen up the heads on a '48-'65 Harley-Davidson, Kibblewhite's Black Diamond valve kit swaps in a full set engineered to outlast the stock parts. Every valve in the kit is fortified by a special process to a depth of .002 inches with a .0002-inch surface buildup, a treatment that improves wear resistance, cuts friction, and guards against corrosion far better than the factory finish. The valves run fine on both leaded and unleaded fuel, so there's no compatibility worry when sourcing gas for an older engine, and every kit is made in the USA to Kibblewhite's own quality standard.
