KPMI Valve Kit 20-22400 for Harley-Davidson Shovelhead 74 1966-1977
$220.00
This KPMI Black Diamond valve kit delivers superior performance and durability for vintage Harley-Davidson Shovelhead engines. Each one-piece forged stainless steel valve undergoes a specialized German impregnation process that significantly improves wear resistance, minimizes friction, and offers protection against corrosion superior to standard chrome or nickel electrolysis plating.
Engineered using Finite Element Analysis and validated on computerized flow benches, these standard-sized intake and exhaust valves feature optimized profiles designed to maximize airflow and engine efficiency. Lightweight yet exceptionally strong, this full set provides reliable valvetrain stability for demanding riding conditions.
