FAQ
Does this kit include head gaskets?
No. This is the complete engine gasket set without head gaskets and without head bolts.
How do I confirm it fits my truck?
Match model year (2004.5–2007) and engine VIN: LLY is VIN “2”; LBZ is VIN “D”.
Are the exhaust manifold gaskets MLS?
Yes—the set uses multi-layer steel where required (e.g., exhaust manifold) for durability.
What other parts should I pair with this?
Add LBZ/LLY head gaskets (grade matched), head studs/bolts, and fresh coolant. See Recommended Products below.
