What is Multi-Layer Steel (MLS) construction?

MLS gaskets are made from multiple layers of stainless steel, typically three to five. This design provides increased strength, better sealing capabilities, and resistance to corrosion compared to older gasket materials.

What is the purpose of the Viton coating?

The Viton rubber coating on the outer layers helps the gasket seal effectively in demanding conditions and on various surface finishes. It's also heat resistant up to 482°F (250°C), making it suitable for high-temperature engine environments.

Does this gasket come with any hardware?

This product is for the cylinder head gasket only. Hardware such as head bolts or studs are typically sold separately and should be checked for compatibility with your specific engine build.
