Ebay/ Pro Comp Head Studs Vs. ARP Vs. GM Strength Test!
With all the buzz around the ebay/ pro comp head studs available I wanted to do a side by side test! For this testing we had to contact a Metallurgical Services company to do a stress test on all three configurations!
The Competitors:
ARP 12 point Head Studs
Ebay/ Pro Comp 12 point Head Studs
GM Stock Head Bolt
(I figured why not kick a gm bolt in the test just for reference)
I was really surprised by these results! What do you guys think?
(shiny bolt is arp -- dull is pro comp/ebay -- gray bolt is GM stock
Interesting. The stock GM bolt is better than the Ebay/Pro Comp studs. It would have been interesting to see how the ARP head bolts compared to the studs.

Shouldn't be much different at all. It's just testing the tensile strength of the material.
