ARP Custom Age 625+ Cylinder Head Stud Kit Exhaust Hardware 2LSU sensors are laboratory calibratedCUSTOM AGE 625 PLUS: This newly formulated super alloy 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. Typical tensile strength is
