WCFab Billet Aluminum Upper Valve Cover sets fit LLY, LBZ, and LMM Duramax and are a great way to clean up your engine's appearance. Integrated o-ring seal replaces OEM gaskets and prevents the need for use of silicone sealers. Includes countersunk stainless steel fasteners and black anodized #10 JIC (-10AN) PCV fittings. Finished in raw aluminum ready for polishing or painting standard. Custom Color Powder Coat finishes available as an optional upgrade and carry additional lead time. 

We recommend pairing these with our Top Outlet Billet Thermostat Housing and Upper Coolant Pipe kits (or a forward facing thermostat setup) because these valve covers do not include brackets for the side mount routing of the OEM setup.

***NOTE: These valve covers do not have OEM style mounting bosses to accept factory fuel filter housing bracket and other OEM type items. Modifications to wire harness tabs and mounting brackets are necessary for installation of this product***
