What is the purpose of the HP shim technology in this gasket?

The HP shim technology increases the clamping force around the combustion chamber. This helps to create a stronger seal, particularly important for engines with an open deck block design like the Coyote V8.

What is Viton and why is it used on this head gasket?

Viton is a high-performance fluoroelastomer known for its excellent resistance to heat and chemicals. Coating the outer layers with Viton helps ensure a reliable seal against combustion pressures and engine fluids.

Does this head 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.

About this part

Product Details

This Cometic MLX head gasket is built for the 2015-2017 Ford Mustang 5.0L Coyote Gen-2 V8 engine. It features a 94mm bore and a .051 inch thickness, designed to work with the open deck block design.

This is especially important for maintaining a strong seal on engines with an open deck configuration.

The outer layers of this gasket are embossed and coated with Viton, a high-performance fluoroelastomer known for its resistance to heat and chemicals. This coating helps ensure a robust seal against combustion pressures and fluids, contributing to the overall reliability and longevity of your engine's seal. If you're rebuilding the top end of your Coyote V8 or need a dependable replacement for your Mustang, this gasket offers a well-built solution.
