2011-2016 GM Duramax 6.6L LML Oil Pans, Valve Covers & Accessories

As the name implies, a valve cover for your 2011-2016 GM 6.6L Duramax LML simply covers the valves and protects the internal components from the outside elements when you're behind the wheel. Typically this cover doesn't impact engine performance unless it becomes cracked or damaged; however, many diesel truck owners like to swap out the original when rebuilding their engine for preventative maintenance. Here at Alligator Performance, we carry a selection of these valve covers that will maintain a consistent and reliable seal on your engine components without compromise.
