Upgrade your 2003-2010 Ford 6.0 Powerstroke with the ARP 250-4202 Head Stud Kit from XDP. It's a proven fact that OEM head bolts are the weak link in a diesel engine; especially if the engine has been modified. That's because most engines are typically assembled from the factory using Torque-To-Yield (TTY) bolts and preloaded to yield and beyond (typically 100-110%). Any increases in combustion pressure can lead to problems like blown head gaskets or catastrophic engine failure and because TTY bolts are yielded by design, they should never be re-used.ARP is the industry leader when it comes to fasteners and manufactures heavy-duty head studs for a wide variety of popular diesel applications. Using 6.0 ARP head studs instead of standard head bolts provides your engine with the clamping force required to keep your cylinder heads from lifting and blowing a head gasket due to higher combustion pressures. For the Ford 6.0 Head Studs, ARP starts with a premium grade ARP2000 alloy that is rated far superior to aircraft quality alloy steels. ARP2000 is an alloy steel that can be safely heat treated to a higher level, producing a greater strength material than Chrome Moly 8740. While 8740 and ARP2000 share similar characteristics, ARP2000 is capable of achieving a higher clamp load at 220,000 psi.Each stud is placed vertically into special racks and precisely heat-treated. This procedure ensures complete heat penetration, and the results are far superior to those lesser quality Ford 6.0 head studs from other manufacturers who just dump pieces in a basket and hope for the best. ARP head studs then go through a centerless grinding process to ensure that they are perfectly concentric. As many as ten machining steps are required to achieve this level of accuracy. The thread rolling operation (to MIL-S-8879A specs) is also done after the heat-treatment, which gives them about 2000% (that's twenty times) better fatigue strength than lesser studs that are threaded prior to heat-treat. It costs a lot more to do it this way, because it's tough on tooling, but the results are well worth the extra effort. Fasteners are then shot-peened to remove any surface irregularities and improve overall external integrity. The final step is a metal finishing process that is also performed in-house at ARP with a black oxide coating applied for long lasting corrosion resistance.There is a good reason that virtually every top professional engine builder relies on ARP head studs for their all-out competition powerplants. Simply put, there's not a better stud setup on the market today. These 6.0 Powerstroke ARP Head Studs are a direct-fit for 2003-2007 Ford F-250/350/450/550 Super Duty, 2004-2010 Ford E-Series Vans, as well as the 2003-2005 Ford Excursion. ARP also offers Inner Row Head Bolts as an add-on to compliment this head stud kit (sold separately, see related items below).
Features:
Proprietary ARP 2000 MaterialRated At 220,000 Psi Tensile Strength
Includes Chrome Moly Steel 12-Point NutsBlack Oxide Coating For Added Corrosion ResistanceCenterless Ground To Ensure They Are Perfectly ConcentricImproved Clamping Force Prevents Cylinder Heads From LiftingBroached Stud Ends Install & Make Cylinder Head Removal EasierHeat-Treated Prior To Thread Rolling And Machining For Optimum Fatigue StrengthShot-Peened To Remove Any Surface Irregularities And Improve Overall External IntegrityHardened Parallel Ground Washers For An Even Load Distribution And Accurate Torque ReadingsComes With 0.5oz Of ARP Assembly Lubricant XDP Thread Cleaning Chasers (Sold Separately):Both the XD40126TC (for head studs), and XD40128TC (for inner row bolts) are a great add-on that will be critical during installation. Thread Cleaning Chasers are an excellent tool to have on-hand to ensure you have properly cleaned the threads in your engine block before the installation of any fasteners. Clean threads provide accurate torque readings and will help give you peace of mind during your engine build or head gasket repair.Most orders ship within 24 hours. If backordered, a representative will contact you within 1-2 business days.
