What makes this gasket a Multi-Layer Steel (MLS) type?

This gasket is constructed from three to five layers of stainless steel. This design offers increased strength and better rebound characteristics compared to single-layer gaskets, helping to maintain a consistent seal.

What is the purpose of the Viton coating on the gasket?

The Viton rubber coating on the outer layers helps create a robust seal against the engine block and cylinder head. It's designed to withstand high temperatures, up to 482°F (250°C), and various sealing demands.

Does this gasket come with any installation hardware?

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

About this part

Product Details

This Cometic Multi-Layer Steel (MLS) head gasket is built with three to five layers of stainless steel, chosen for its strength and resistance to corrosion. The outer layers feature an embossed design and are coated with Viton rubber, a material that can handle temperatures up to 482°F (250°C) and withstand tough sealing conditions. This gasket is specifically .040 inches thick with an 87mm bore, making it a precise fit for certain Mitsubishi 4G63T engines and compatible Dodge vehicles from 2006-2010.

The stainless steel construction offers improved rebound characteristics compared to softer materials, helping to maintain a solid seal even under varying engine loads. The Viton coating on the embossed layers is designed to create a reliable seal against the engine block and cylinder head surfaces, accommodating different finishes and operating demands. This gasket is a popular choice when rebuilding or replacing the head gasket on these specific performance-oriented engines.
