KIBBLEWHITE - 20-23100 - Black Diamond™ Engine Valve Kit - '05-'17 Harley-Davidson Electra Glide Ultra Classic Low FLHTCUL, Electra Glide Ultra Classic FLHTCU
Riders rebuilding the top end on a '05-'17 Harley-Davidson need valves that won't be the weak link, and Kibblewhite's Black Diamond Engine Valve Kit is built for exactly that job. 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.
