Head gaskets for the 6.7L Cummins (2007.5–2018) seal the cylinder head to the engine block, preventing coolant, oil, and combustion gases from mixing. Built to withstand high compression and extreme temperatures, these gaskets are vital for maintaining engine integrity.

Upgraded options often include multi-layer steel (MLS) construction for improved sealing under boost, especially in performance or heavy-duty applications. Replacing a head gasket is critical during top-end rebuilds or if symptoms like coolant loss or white smoke arise.
