What is MLX technology and how does it help?

MLX stands for Multi-Layer Stopper. This technology uses an integrated stopper layer specifically to seal the combustion chamber. It helps improve the clamp load around the cylinder without causing extra distortion, ensuring a reliable seal for your engine.

Do I need to use any sealant with this head gasket?

No, this Cometic MLX head gasket does not require any additional sealants. It's designed to provide a complete seal on its own, simplifying the installation process.

Does this head gasket require a re-torque after installation?

No, a significant benefit of this gasket is that it does not require a re-torque procedure after installation. This saves you time and ensures the seal remains consistent.

About this part

Product Details

When you're rebuilding the top end of your GM Duramax, you need a head gasket that seals reliably. This Cometic MLX head gasket is built for the 6.6L Duramax engines found in a range of trucks and vans, including models like the Chevrolet Silverado 2500 HD and GMC Sierra 3500 HD, as well as the Chevrolet Express and GMC Savana vans. It's designed with a 4.130-inch bore and a .062-inch thickness, making it a solid choice for many Duramax builds.

What sets this gasket apart is its MLX (Multi-Layer Stopper) technology. It uses an integrated stopper layer specifically for sealing the combustion chamber. This design helps improve the clamp load around the cylinder without causing extra distortion in the bore, which is crucial for maintaining a good seal under pressure. It's made from the same robust materials as Cometic's popular MLS head gaskets, so you know it's built to last. A key benefit is that it requires no additional sealants, and you won't need to re-torque it after installation, simplifying the assembly process.
