Cometic MLS-5 head gasket for 2001–2006 GM 6.6L Duramax engines with a 4.100" bore and 0.060" compressed operating thickness; right-side. The multi-layer stainless construction uses embossed outer layers coated with Viton and an uncoated center shim, delivering sealant-free sealing for high-output diesel applications. It withstands mixed-metal shearing, resists corrosion, rebounds under load, and distributes clamp forces to limit bore distortion.
