Description 1998-Current Dodge Ram 5.9L & 6.7L 24 Valve Cummins Diesel Automotive Racing Products ARP 625 Head Stud Kit Automotive Racing Products ARP part number 247-4204 is a Custom Age 625 head stud kit for 1998.5 (24 Valve) and newer Dodge Ram trucks with a 5.9L or 6.7L Cummins diesel engine. ARP was the first company to design and engineer fasteners specifically for racing. They developed many patented processes for manufacturing high-strength fasteners from very strong materials. ARP has continued to improve their processes and quality control, and is currently ISO 9001 plus AS9100 registered for aerospace manufacturing. There’s not another company in the world that is as focused on building superior quality fasteners for all forms of racing and non-racing applications as ARP. CUSTOM 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 . It is expected to soon replace MP-35 as the material of choice in the high strength, super-alloy field. The typical tensile strength is 260,000-280,000 psi. This is the extreme level head stud kit that performs better than the factory head bolts and the ARP 2000 series. If aggressive modifications like larger injectors, bigger turbo or turbos, and engine programming are used, this kit is recommended.
