Intoducing the Custom Age 625+ head studs from SPEED PERF6RMANC3. These studs have an even higher UTS (closer to the 280 ksi limit of the material) than our previous L19 offering and have the added benefit of better corrosion resistance. We also upgraded the nuts in our head stud package to a heat treated version which have a lower failure rate when paired with an equally heat treated stud. The best part about the new 625+ studs is that we are able to keep the price the same. Many other platforms charge a premium for this material but we believe the price should stay the same even for a better product.
Our 10mm head stud kit comes with upgraded nuts and washers along with a special assembly lube that has been tested to provide the most accurate torque spec of any lube on the market. These are only available through SPEED PERF6RMANC3 and don’t stay in stock very long!

Manufactured by ARP for Speed Performance, these 635+ head studs will handle all the boost that you want to throw at this engine. When I was gathering parts for an Ecoboost job, I found that ARP did not have these in their catalog but the guys at Speed Performance already did the work for us and had them made for them and they have them on the shelf.
That aside, they are good guys to talk to and I appreciated all their help!
