Track-tested at over 30psi of boost, L19 head studs are designed with serious clamping force in mind.

L19 is a proprietory alloy offered by ARP that is MUCH stronger than any off-the-shelf headstud previously available. Exhibiting tensile strength of 260,000psi vs the standard 190,000 - 210,000psi of a typical 8740 chromoly stud; L19's will allow you to turn up that boost while being confident that your cylinder head will stay planted.

Now you're able to utilize this great product in your Nissan QR25DE exclusively through Vision One Racing!
