Fitment
Listed for the 2011-2016 6.6L Duramax LML in Chevrolet Silverado 2500HD/3500HD and GMC Sierra 2500HD/3500HD trucks. The part description also names the LGH version of the 6.6L Duramax for the same 2011-2016 years. We have this kit tagged for the LML, so if your engine is an LGH, verify fitment by VIN or call us before you order. It is not listed for the LMM before it or the L5P after it. You can shop the rest of our Duramax parts by engine.
Why this part
Lower-end work takes real time, and once the bottom of the engine is open, the old gaskets and seals are not what you want going back in. A kit puts the lower end gaskets and seals for the LML under one part number, so you are not piecing the job together from separate orders. MAHLE makes the CS54580B to OE specifications, and the point of that is simple: the engine goes back together sealed the way it left the factory and keeps its factory performance. If you only need to replace a single leaking gasket, check whether that piece is sold on its own first. This kit is meant for a job that opens up the bottom of the engine.
What you get
One MAHLE CS54580B Lower Engine Gasket Kit with the lower end gaskets and seals for the 2011-2016 6.6L Duramax LGH/LML. The listing does not itemize each piece, so if you need to confirm a particular gasket or seal is in the box before you tear down, call the shop and we will check it for you. MAHLE lists these features:
- OE Quality
- Maintains a Factory Performance
About MAHLE
MAHLE has been in the engine business since 1920, when it opened as a small shop in Stuttgart, Germany, building pistons. Its aftermarket line now runs from pistons and bearings to head gaskets, head sets and complete engine gasket sets. These are the hard parts and sealing parts diesel shops have relied on for years, and we stock more than 500 MAHLE part numbers for Duramax, Cummins and Powerstroke engines.
Frequently asked questions
Does this kit include the head gaskets?
This is the lower engine kit. MAHLE sells head gaskets and head sets as separate parts. Call us if you want upper and lower sealing parts matched for a full reseal.
Will it fit an LMM or an L5P?
It is not listed for them. The CS54580B covers the 2011-2016 6.6L Duramax LML, and the part description also names the LGH. For other years, look for the MAHLE kit listed for your engine or send us your VIN.
Is this an OE-quality replacement?
Yes. MAHLE makes the CS54580B to OE specifications to maintain factory performance.
