ARP - Custom Age 625+ Cylinder Head Studs (Evo X)
ARP's Custom Age 625+ material is a newly formulated super-alloy, which demonstrates superior fatigue cycle life, tensile strength, and toughness - with complete resistance to atmospheric corrosion and oxidation. ARP is the first to develop manufacturing and testing processes for fasteners with Custom Age 625+. Best of all, it is less expensive and expected to soon replace MP-35 as the material of choice in the high strength, super-alloy field.
