FAQ
Is this an “upper” or “full” gasket set?
This is an upper (top-end) set designed for head-off service. Bottom-end components such as oil pan or rear main seals are not included.
Will this fit my 2012 Ram 2500 6.7L?
Yes, 2012 falls within the 2007.5–2018 coverage. Always confirm by VIN/ESN for exact compatibility.
Does the kit include head bolts or studs?
No. Bolts/studs are sold separately and should be replaced per manufacturer recommendations.
Do I need to choose a head gasket thickness?
Follow Cummins procedures to determine required gasket grade based on piston protrusion and service manual specs.
