Will this fit my 2003–2007 5.9L Cummins?
Yes—this kit fits 2003–2007 Ram 2500/3500 trucks with the 5.9L 24-valve Cummins (VIN C).

No. Head bolts/studs are sold separately. Pair with quality bolts or studs during reassembly.
Is the head gasket MLS and over-bore?
Yes—this set includes a 1.20 mm service-specific over-bore, multi-layer steel head gasket designed for durability under cylinder pressure.
Do I need machine work?
