To overcome head gasket failures that can occur in diesel engines employed in truck and RV applications, industry leader ARP has introduced extra heavy-duty head studs. These ARP studs are rated at 220,000 psi tensile strength, and provide the clamping force required to keep cylinder heads from lifting due to higher combustion pressures.

Replace the factory Flex Plate bolts in your 1998.5-2007 Dodge 5.9L Cummins with the ARP 147-2901 Flex Plate Bolt Kit. Flexplate bolts play an important role in the performance and safety of race vehicles and street machines. That's why the fastener experts at ARP have developed special bolts that are far superior to OEM hardware. ARP Flexplate bolts feature an exclusive flat 12 point head design and a larger than stock underhead radius for increased strength. Each bolt is centerless ground to ensure the bearing surface is perpendicular to the threads creating equal load distribution. Optimum design, enhanced reliability and increased strength are the main attributes of ARP's Flexplate Bolts.

ARP Diesel Main Stud Kit - 250-5801

ARP recommends the use of main studs 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.
