New valves from Erson Cams are designed for high performance diesel applications. Intake valves are made from 21-4N stainless alloy and exhaust valves are Inconel alloy with a stellite facing for maximum durability under the extreme heat and stress produced by turbocharged and supercharged diesel engines.

All valves feature full machined heads with swirl polished stems for increased flow and consistency, and are fully Nitrided to increase strength and create a much smoother surface finish for less valve and guide friction, resulting in less wear and more power. They also offer improved corrosion resistance when used with exotic fuels, including nitrous. Available for Powerstroke, Duramax and Dodge Cummins engines.
