What is a multi-layer steel (MLS) head gasket?

A multi-layer steel head gasket uses several layers of steel stamped and coated to create a strong sealing surface. This design is common in modern engines because it can better withstand the high pressures and temperatures found in the combustion chamber compared to older composite gaskets.

What vehicles does this MAHLE Original head gasket fit?

This gasket is made for the 6.6L Duramax L5P engine and fits the 2017-2022 model years of the Chevrolet Silverado 2500 HD, Chevrolet Silverado 3500 HD, GMC Sierra 2500 HD, and GMC Sierra 3500 HD.

What else might I need when replacing a head gasket?

When replacing a head gasket, it's often recommended to also inspect and potentially replace head bolts, as they can stretch under heat and pressure. Always refer to the manufacturer's service manual for a complete list of recommended parts and procedures for your specific vehicle.

Product Details

This MAHLE Original cylinder head gasket is built with a multi-layer steel (MLS) design, a common choice for modern engines because it handles the high pressures and temperatures found in the 6.6L Duramax L5P. It's designed to seal the combustion chamber, oil passages, and coolant passages between the engine block and the cylinder head, ensuring proper engine operation and preventing leaks.

When you're rebuilding the top end of your 2017-2022 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD, a solid head gasket is crucial. This gasket from MAHLE Original is a well-built replacement that aims to restore the seal between your cylinder head and engine block. The multi-layer steel construction offers good resilience against warping and blowouts, which is important for keeping your Duramax running smoothly.

This gasket is specifically made for the 6.6L Duramax L5P engine found in the specified GM trucks. Make sure to follow the manufacturer's installation instructions carefully, as proper torque sequencing and cleanliness are key to a successful head gasket installation.
