To overcome head gasket failures that can occur in diesel engines employed in truck and RV applications, industry leader ARP has introduced extra heavy-duty head studs for the popular Ford, Dodge and GM powerplants. These ARP studs are rated at 220,000 psi tensile strength, and provide the clamping force required to keep cylinder heads from lifting due to higher combustion pressures.

The studs are manufactured in ARP's Santa Paula, CA plant from proprietary ARP 2000 material, with threads rolled after heat-treat to provide optimum fatigue strength. They are centerless ground to assure perfect concentricity. The ends of the studs are broached to facilitate easy installation. This feature also enables the cylinder head to be removed in tight quarters. Also included in each kit are heat-treated, chrome-moly steel 12-point nuts and parallel-ground washers. They are black oxide finished for extra durability.

Just finished up the upgrade to the head studs, other than working on a lifted truck and laying in weird angles, the install was simple and straight forward. Had about 100,000 miles on the truck and just increased the HP. I wanted no worries in the potential of lifting the head so ARP studs installed!!. I believe this was a great investment and quality product. I did order more lube to go with this, the 10oz bottle was over kill, ordering the 1.5 oz tube along with what the kit comes with would be enough.
Straight forward install

I installed these head studs about a year ago with a turbo upgrade on my late 04. I had about 225000 miles of the truck at time and did them with out removing the head. The instructions lay everything out step by step if you are replacing the head gasket at same time, if you are completely removing head I recommend having it check by a machine shop for straightness. As said in the other review you will need to order more ultra torque lube the little packet that comes with the studs will only get you trough about four of them. If not removing the head pay attention to how far the stud has screwed into the head. Had a couple that the hole filled in with some engine oil and cause a slight hydraulic effect, which if you take your time threading in you will get it to bottom out. I have had no issues with head gasket since install and have worked the truck hard. (order# 526521)

Note: It will be necessary to machine the lower rocker arm cover at the No. 24 bolt hole location in the torque sequence to facilitate installation of the lower rocker arm cover

Will these head bolts work on a 2014 6.7L Cummins?
View Staff Answer 

The ARP studs are listed on the manufacturers site for the Dodge Cummins 5.9L/6.7L 24V '98 - Present.

Can you change one at a time?
View Staff Answer 

Yes it can be done. You must maintain stock torque on the cylinder head until all stock bolts have been replaced with ARP studs one at a time. After this is done, you can then follow the torque sequence to being bringing the stud up to their final torque. (This is done in small increments.)

What is the maximum torque?? 125 seems very little
View Staff Answer 

125 ft/lbs is the max recommended by ARP - In actual practice many installers go to 135 ft/lbs
