What is the advantage of Multi-Layer Steel (MLS) head gaskets?

MLS head gaskets offer increased strength and resistance to corrosion due to their multiple stainless steel layers. They also provide maximum sealing performance for high-output engines and don't require additional sealants.

What is the role of the Viton coating on this gasket?

The Viton rubber coating on the outer layers is heat resistant up to 482°F (250°C). It's designed to meet the demands of harsh sealing environments and various surface finishes, ensuring a reliable seal.

Does this gasket come with any hardware?

This product is for the head gasket only. It does not include head bolts or other installation hardware, which should be sourced separately if needed.
