Cometic MLS head gasket for 2001–2006 GM 6.6L Duramax engines with a 4.100" bore and 0.051" compressed operating thickness; right-side. Built from multiple embossed stainless layers with Viton-coated outer surfaces and an uncoated stainless shim core, it seals diesel heads without sealants. The MLS design resists corrosion, rebounds under load, accommodates mixed head/block materials, and evens clamp loads to reduce bore distortion and sealing issues.
