These studs are manufactured specifically for us by ARP and utilize an L19 material that is much stronger than the typical 8740 chromoly and yields a tensile strength of 240-260,000 psi. They are also provisioned with a hex broach on the top of the stud for ease of installation and enabling you to install them with the cylinder head on the car if necessary.
What makes these head studs better than the competition?
Initially these might look just like other ARP and A1 Technologies head studs available on the market, but that isn’t the case.
