ARP
There are a number of important elements in the production of specialty fasteners, not the least of which are materials, design and manufacturing. Extensive backgrounds in mechanical engineering, metallurgy and stress analysis complement the extraordinary steps taken by ARP to produce the very finest products of their kind on the market today. ARP's product line contains thousands of part numbers, and has expanded to include virtually every fastener found in an engine and driveline. These range from quality high performance OEM replacement parts to exotic specialty hardware for Formula 1, IndyCar, NASCAR and NHRA drag racing and marine applications. Their head stud kit for diesel truck applications provides the solution to a problem that many have experienced. OE head bolt stretching has been a problem to many diesel truck owners, both those who are into diesel performance and those whose truck is still stock.

The ARP 150-5801 Main Stud Kit for your 2003-2007 Ford 6.0L Powerstroke is recommended over bolts whenever possible for several key reasons. First is the ability to obtain more accurate torque readings because studs don't "twist" into the block. All clamping forces are on one axis. By the same token, there is less force exerted on the block threads, which contributes to improved block life.
Finally, the there are factors of easier engine assembly and proper alignment of caps every time. All kits come complete with hardened parallel-ground washers and high quality nuts. The studs are manufactured from 8740 chrome-moly steel, heat-treated in-house to 200,000 PSI tensile strength, and precision J-form threads rolled after heat-treat to create a fastener that has threads 2000% stronger than others.
