BLACK DIAMOND EXHAUST VALVE HD SPORTSTER 57-69 UTV Vehicles>>Polaris crisp sound and horsepower gainsAll KPMI Black Diamond stainless steel valves are impregnated by a special German process to a depth of . 002, with a surface build up of . 0002. This Black Diamond process improves wear properties, reduces friction, and provides resistance to corrosion and wear that is superior to chrome and nickel electrolysis plating. Black Diamond Valves are light, strong, one piece forgings with profiles that provide excellent flow characteristics.
