97.5-2007 Dodge 5.9L Cummins Main Studs
Not sure if yours is a 97.5 block? Look on the passenger's side of the engine. If there are 2 turbo drain ports, you have a 97.5. Please call if you have further questions.

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 (very critical on aluminum blocks). Finally, there are factors
of easier engine assembly and proper alignment of caps every time.

There are many important reasons to use ARP main stud kits, including the elimination of main cap walk and fretting, as well as protecting the threads in your engine block. All kits come complete with hardened parallel-ground washers and high quality nuts. Some applications have provisions for mounting windage trays and have specially designed standoff studs with serrated lock nuts to position the windage tray and lock it securely in place. The studs are manufactured from 8740 chrome molysteel, heat-treated in-house to 200,000 psi tensile strength, and precision J-form threads rolled after heat-treat to create a fastener that has threads 1000% stronger than others

Please note: These studs WILL work on a 03+ Dodge 5.9L Commonrail, but some machining will have to be done to the stock block stiffener for clearance.
