About to have ARP studs installed.

Hey guys. The truck's at the dealer needing head gaskets. I'm supplying them with ARP studs in place of the stock crap. Does anyone know the tensile strength of the stock studs by chance? I know the ARP's T-strength is stated to be around 220,000psi. Thx.

I heard the stock ones were also 220,000 tensile strength.....and I also heard that tensile strength doesn't matter.

Hmmm....I wonder then, exacty what metalurgic property is responsible for resisting necking or the stretching in the studs, which ultimately causes the heads to lift. I'd be interested to hear what does matter if tensile strength doesn't.

There is a good discussion thread over on PSN in the 6.4L Aftermarket forum that is all about ARP studs vs. Elite H-11 studs. I can't remember what the title of the thread is, but the "search" function should help you out.

Did you blow your Head Gaskets with the 310 tune?

Head BOLTS (factory) can't be torqued to the same number as head STUDS. More torque on the heads = tighter seal on the gaskets = less likely to blow.

He told you that their tow power turbo's will work without head studs or an EGR delete w/wastegate? That sounds a little far fetched to me.

It's not about tensile strength, or the amount of torque put on them.

It's about fatigue. Tensile strength is how much it takes to actually break them in two. Fatigue is the amount of "stretch" a bolt allows before failing.

ARP's studs allow much less of this stretching to occur and it's all about the metalurgic properties of that specific fastener. When a head gasket blows, most times it doesn't actually break the studs, the stud just stretches and allows the explosive gasses to get under the head.

Dieselkane, The intital leak occured when running the 310. I'd been running the 210 for almost a year with no problems and had just recently retuned with the 310. At first I had a very small leak, visible only by a small stain on the driveway. I took it to the dealer and they said it was the radiator. That was replaced on my dime and on the way home with the new $1150.00 , I lost at least a gallon of coolant on the 10 mile trip. I called again, they sent a tech to my house to look and make sure he didn't F/U something. nothing was found while he was here. The tech drove the truck back to the shop and a few days later i was told that it was the head gaskets. I am having the old radiator pressure tested by a third party, assuming I payed for a radiator replacement that wasn't needed. Still waiting to hear on that.
