  • Valve stem is 21% smoother than  a chrome plated stem. This has  been proven in scanning electron  microscope examination.
  • Smoother valve stem means  less valve and valve guide friction,  resulting in less wear and  more power.
  • Stronger and more corrosion  resistant than a chrome plated valve.
  • More ductile throughout the entire  valve material than a valve that is  not five step liquid nitrided. Proven in Rotating-Bending Fatigue Tests.
  • Valve is less likely to break even if contacted by the piston.
  • Improved corrosion resistance  when used with exotic fuels,  including nitrous.
  • Our nitrating process is much cleaner than chroming. It’s better  for the environment.
