ARP fasteners makes the best and strongest engine main studs on the market today. Your GM 6.6L Duramax came from the factory with main cap bolts . The factory main bolts were designed to stretch but over time the bolts stretch past the designed length and allow the bearing caps to "walk". With ARP main studs there is no more stretch and thus preventing issues with mains walking.
