What does the .040 inch bore size mean for my engine?

The .040 inch bore size indicates that this gasket is intended for engines where the cylinders have been enlarged beyond their original factory dimensions. This ensures a proper seal in a modified engine build.

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

Viton is a high-performance synthetic rubber known for its excellent resistance to heat, oil, and other fluids. Coating the gasket's outer layers with Viton helps create a more robust seal and improves its durability in harsh engine environments.

Does this gasket come with any hardware or sealant?

This product is for the cylinder head gasket only. It is recommended to use new head bolts and follow the manufacturer's specific installation instructions, which may include the use of appropriate sealants in certain areas.

About this part

Product Details

This Cometic MLX head gasket is built with embossed outer layers that are coated with Viton, a material known for its resistance to heat and oil. This gasket is specifically made for the Chrysler 6.4L Apache Gen-3 Hemi engine and features a 4.150-inch bore, which is .040 inches larger than stock, making it suitable for engines that have been bored out. It's designed for the right-hand side (RHS) cylinder head.

When you're rebuilding the top end of your 6.4L Hemi, a well-made head gasket is crucial for sealing the combustion chamber and coolant passages. The MLX design from Cometic uses advanced materials and construction techniques to ensure a strong seal under demanding conditions. The .040 inch oversize bore means this gasket is intended for engines where the cylinders have been enlarged, ensuring a proper fit and seal in those modified applications.

This gasket fits a wide range of Chrysler, Dodge, Jeep, and Ram vehicles equipped with the 6.4L Hemi engine, including models like the Dodge Challenger, Charger, and Ram 2500. Always refer to the manufacturer's installation instructions for proper torque sequences and procedures to ensure optimal performance and longevity.
