Dodge Cummins 6.7L 2007 - 2016, with factory girdle (block stiffener plate), 2 bolt.
Main Stud Kit
The ARP 247-5405 Main Stud Kit for your 2007.5-2015 Dodge 6.7L Cummins is recommended 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.
