FAQ
Is this the correct set for LMM trucks?
Yes. CS54580A fits 2007.5–2010 LMM Duramax applications.
Does this include head gaskets?
No. This is a lower engine/conversion set. Pair with a head set (e.g., HS54580B) for a full engine gasket kit.
Are the materials OE-equivalent?
Yes—MAHLE Original uses OE-equivalent or better materials and meets/exceeds OE specs.
What other parts should I replace while I’m in there?
Consider rear main seal, front crank seal (if not included), oil pan gasket, and fresh fluids. Inspect crankcase ventilation parts and seals.
