The ARP rod bolts are still in development here.. I approach these things that will be included on our engines with extreme care. We'll be running a set in our ITR car next season, I plan on a tear down at 20 hours to measure stretch and etc compared to the stock units.

The main reason for this is to find the optimum torque values and procedures, things that the MFR normally can't dictate absolutely and only practical application will quantify.

Until then the billet rods are the only proven solution as they use an ARP custom aged bolt that I have 13 years of experience with at outputs over 650HP.
