Upgrade the valve covers in your 2011-2016 GM 6.6L Duramax LML with the HSP LML Billet Valve Covers. Designed to give your engine a dressed up look, the HSP Valve Covers are built from 6061-T6 aluminum and are available in multiple colors to match your truck. HSP Billet Valve Covers feature an o-ring seal to eliminate the need for silicone. It's recommended to run these valve covers with their forward facing thermostat housing as there are no provisions to mount the factory hardware to the upper valve cover. 1/2" center port for optimized crankcase ventilation.
