(16)21-4N Forged Stainless VALVES
10+ CFM Air Flow increase over Stock
•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 nitrated. 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 nitro-us.
•Our nitrating process is much cleaner than chroming. It’s better for the environment.
