| Price | Included in base price | Added cost (ARP parts cost more) | Added cost |
| Why choose it | Shop-proven; we have run them for years | Long-established name trusted for decades | ARP's premium stud material, often chosen for heavily modified, high-boost builds |
| Our take | All three are solid choices for a stock, mild or wild built truck. Pick the one that fits your build. | ||
All head stud choices are in the same head stud dropdown. Pick one.
Optional. With the head already off, these parts fit the 5.9L Cummins and are worth considering now:
Do I need head studs?
Yes. The head stud set is the one required option, and each kit takes one set. Factory torque-to-yield head bolts are single-use, so the base price includes Tracktech studs; ARP 2000 and ARP 625+ studs are available for an added cost. Follow the stud maker's included instructions for installation.
Why only one head gasket?
The Cummins is an inline six with a single cylinder head, so it takes one head gasket.
Does this fit a 2007.5 truck?
No. Trucks built from 2007.5 on have the 6.7L Cummins. Use our 2007.5-2018 6.7L kit.
