207-4302 - ARP 94+ Mitsubishi 4G63 M11 Custom Aged 625+ Head Stud Kit

ARP Custom Age 625 Plus

ARP's Custom Age 625 Plus material is a newly formulated super-alloy that 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 is expected to soon replace MP-35 as the material of choice in the high-strength, super-alloy field. Typical tensile strength is 280,000 psi.
