This is what you need if you are looking to keep those main caps from walking around and hold your 7.3L together in high stress situations.  The kit will come complete with ARP main studs and the tab for the oil pick up tube.   Just have your machine shop align bore your crank and you are set!  

** Will NOT work on 94-95 without swapping the front cover to the newer ones!  

***ARP studs are final torqued to 125ft/lbs from the center out.
