Product Description
The ARP 247-4202 Head Stud Kit is one of the most trusted cylinder head fastener upgrades for 1998.5-2024 Dodge Ram and Ram 5.9L/6.7L Cummins 24V engines. Designed to deliver stronger and more consistent clamping force than factory head bolts, this kit helps improve head gasket sealing in trucks used for towing, tuning, higher boost, and performance diesel applications.

WHY UPGRADE TO ARP HEAD STUDS?
Factory head bolts can become a weak point when boost pressure, fueling, towing load, or cylinder pressure increases. ARP head studs provide stronger clamping force to help keep the cylinder head sealed to the block, making them one of the most important upgrades for a modified 24-valve Cummins.

Hold that head down
I have always been a believer in head studs vs head bolts. ARP provides options for head studs, depending on the level of your build. I am confident that the head studs will keep my head secured.

The extra security....
Makes it completely worth the investment. My set was missing a long stud, BUT when I informed CPP and ARP about the incident they both jumped all over it and took care of it within 24 hours, at my door, ready for install.
