ARP Head Stud Kits for 2007.5-2010 6.4L Ford Powerstroke Diesel

These Pro series studs from ARP are cold-forged to ensure molecular integrity. They are heat-treated prior to thread rolling and machining and are rated at a whopping 190,000 psi. The Pro series kits are also available with 12-point nuts, and all kits come complete with hardened parallel washers for an even load distribution and accurate torque readings.
ARP uses a premium grade 8740 alloy that is rated far superior to aircraft quality. Then, each stud is placed vertically in special racks and precisely heat-treated to 200,000 psi. ARP studs are thread rolled after heat-treat, which gives them about 1000% (thats ten times) better fatigue strength than those studs that are threaded prior to heat-treat (a very common industry practice).
Manufactured in ARP's Santa Paula, CA plant from proprietary ARP 2000 material.
Premium parallel ground washers are also included with each kit.
TECH TIPS: HEAD STUD INSTALLATIONS
Clean and chase all bolt threads in block to ensure proper thread engagement and accurate torque readings.
All hardware should be cleaned and inspected for possible shipping damage prior to installation.
Since most studs extend into the water jacket, coat threads with ARP thread sealer and screw in hand tight ONLY.
Install gasket and head, then lubricate washers and nuts with oil or ARP moly assembly
