What is the difference between MLX and MLS head gaskets?

MLX (Multi-Layer Stopper) gaskets, like this one, use an integrated stopper layer for enhanced sealing and clamp load. They are made from the same materials as MLS (Multi-Layer Steel) gaskets and offer similar durability and performance.

Does this head gasket come with any hardware?

This product is for the head gasket only. Any necessary head bolts or other installation hardware would need to be purchased separately.

What does the .040in thickness mean for my engine?

The .040 inch thickness refers to the compressed gasket height. This specific thickness is important for maintaining the correct compression ratio and valve-to-piston clearance in your 5.0L Coyote V8 engine.

About this part

Product Details

When you're rebuilding the top end of your 2015-2017 Ford F-150's 5.0L Coyote V8, a solid head gasket is crucial for proper engine function. This Cometic MLX head gasket is specifically made for the Gen-2 Coyote engine, featuring a 94mm bore and a .040 inch thickness, designed to seal the combustion chamber effectively.

Cometic's MLX (Multi-Layer Stopper) technology uses an integrated stopper layer. This design helps improve the clamp load around the cylinder for a better seal without causing distortion to the bore. These gaskets are constructed from the same well-built materials as Cometic's popular MLS head gaskets, ensuring durability and reliable performance for your F-150.

One notable benefit of this gasket is that it requires no additional sealants and does not need to be re-torqued after installation, simplifying the assembly process. This makes it a straightforward component to install when working on your engine.
