ARP 247-4202 Diesel Head Stud Kit Dodge Cummins 5.9L/6.7L 24V '98-present

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.
