The MAHLE cylinder head gasket in Grade B, 1.00 thickness, is a single head gasket for the 6.6L Duramax in 2001-2016 Chevrolet and GMC heavy-duty trucks. MAHLE grades the Duramax head gasket by thickness, and this is the Grade B version at 1.00. You buy it when a head is coming off and the gasket underneath has to go back new.
Fitment
Fits the 6.6L Duramax in 2001-2016 trucks. The 6.6L ran in several versions across those years, so the year alone does not settle it. More important here is the thickness grade: this gasket is the Grade B, 1.00 version, and the grade has to match what your engine calls for. Pick it by the grade your engine needs, verify fitment by VIN, or call us and we will match it. Do not cross a 6.6L Duramax head gasket with any other engine.
Why this part
The head gasket seals the cylinder head to the block and keeps combustion pressure where it belongs. Any time a head comes off a 6.6L Duramax, whether for a reseal, a head job or head studs, the gasket under it is a one-time part and goes back new. Running the correct thickness grade is what keeps the deck sealed, so match the grade to your engine instead of guessing.
What you get
- One MAHLE cylinder head gasket for the 6.6L Duramax, Grade B, 1.00 thickness
This is the head gasket on its own. MAHLE catalogs its Duramax head sets and complete engine gasket sets as separate parts, so order those by their own numbers if your job needs more than the one gasket.

Frequently asked questions
Which thickness grade do I need?
MAHLE grades the Duramax head gasket by thickness, and this listing is the Grade B version at 1.00. The grade has to match your engine, so confirm the right grade before you order. Send us your VIN and we will help you check.
Does this fit every 2001-2016 6.6L Duramax?
It is listed for the 2001-2016 6.6L Duramax. Because the 6.6L came in several versions over that span, verify fitment by VIN before you buy.
Is this a full gasket set?
No. This is the cylinder head gasket by itself. MAHLE sells head sets and complete engine gasket sets under their own part numbers, so call us and we will line up what your reseal needs.
