KDD Duramax Stainless/Inconel Nitrided Valves
Upgrade the valves in your Duramax to these premium stainless intake/inconel exhaust valves, nitride coated and swirl polished for lasting quality in the most demanding conditions. Inconel is the highest quality material available for diesel exhaust valves. These are a direct replacement for factory Duramax valves, plus we use these top shelf valves in 100% of our new KDD/Mast Duramax cylinder heads. Don't forget to check out our valve spring upgrade kits, also used in our Duramax cylinder head program.
