        Great Product

        I fought in my head on whether to go ARP or not. If I did them in one spot I would feel compelled to put them anywhere I could. I did main studs, harmonic balancer bolt, and the head studs. Reusable, and great quality. ARP also came with the rods I got. I will use ARP on every build going forward.

        Killer head studs

        Even just the feeling of the bolt in your hands, they feel super durable and no where close to cheap. Definitely recommend ARP studs!

      Can you reuse these Head Studs? I have them on my motor and it is coming apart for a refresh.

      • You can reuse the ARP Head Stud Kit - 12 Point (96-04 4.6L) since they are are not a flex stud. ARP bolts are solid and will not flex, thus you are able to reuse them.
