FAQ
Is this everything I need for a full rebuild?
This is the lower engine set. For a complete overhaul you’ll also need an upper/head set and any one-time-use fasteners, plus bearings, rings, etc. as required.
How can I confirm fitment?
Check your VIN and engine serial number (ESN). This set is for 2003–2007 5.9L common-rail engines only.
Do I need additional sealant?
Yes—some joints specified by Cummins require RTV in addition to the supplied gaskets. Follow the service manual for exact locations.
