I have found that ARP makes a set of main studs for the 04 and up 5.9 cummins that will clear the stock block stiffener. I thought this was neat but my truck is an 03... Does anyone have any info on what the difference is between the 03 and newer CRs as far as why ARP would list these for 04 and up and not all CR trucks. Ive tried calling ARP and the person I talked to seemed to have no clue what I was talking about.
