Deviant 72800 Valve Cover | 04.5-10 GM 6.6L Duramax 2500HD / 3500HD

We designed these valve covers for the 2004.5-10 Duramax 6.6L engines. One piece o-ring seal, provided counter sunk fasteners makes for a very clean install. The PCV provisions are over sized to 3/4 inch, and an ORB to -12 JIC adapter is included. Finish is raw aluminum engraved with Deviant Race Parts logo.
