Tensilite Titanium Exhaust Valve

All KPMI titanium valves are manufactured from solid U.S. milled titanium bar..The titanium bar is cut, forged and then the stem is pulled from the forging process and cross-sectionally reduced..After all final grinding and machining the valve is encased in a hard titanium nitride shell..We have tested these valves in the lab and on the track..They have proven themselves time after time in many high-demand applications, from a dual stage nitrous motor to a recent Superbike from Hell
