Made with premium Super Clean Chrome silicon Vanadium Steel alloy for higher performance and durability at high rpm's and better memory. The valves are computer designed to ensure that wire stress levels do not overpass the limits of stress defined in the diagrams of fatigue for long durability under extreme conditions. Computer software also allows us to make sure that the harmonics are well under control limits.
