1998-2025 Cummins 6.7L ARP2000 Head Stud Kit (247-4202)
The ARP 247-4202 Diesel Head Stud Kit from OCDiesel let's you build your Dodge Ram 5.9L/6.7L Diesel engine to last. 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 and builds heavy-duty head studs and fasteners for a wide variety of popular diesel applications. Using head studs instead of standard bolts provides your engine with the clamping force required to keep your cylinder head from lifting due to higher combustion pressures. For the 247-4202 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 studs from other manufacturers who just dump pieces in a basket and hope for the best. The head studs next 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 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 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.
It is for good reason that virtually every top professional engine builder relies on ARP head studs for their all-out competition powerplants. Simply stated, there's not a better stud setup on the market today. This head stud kit is a direct-fit for 24-valve 5.9L and 6.7L diesel engines found in Dodge Ram 2500/3500 pickups.
