Fits: 2004.5-2010 GM Duramax LLY, LBZ, LMM
Sinister Diesel's Billet Valve covers for the 2004.5-2010 Duramax will help clean up the engine bay, and add a little more clearance for custom turbo or fuel upgrades. These are fully CNC machined, then they are anodized in the Sinister Blue color for good looks and a long life.
These retain the factory Fuel Filter housing as well as the Radiator hose hard line.
These DO NOT have any other provisions for wiring harnesses or accessories. These will work on a stock truck with the wiring harness tied back.
Upper valve cover includes new gaskets, and will retain factory hardware, or will work with aftermarket hardware like the ARP dress up kit.
