MPP Billet Main Caps (11-19 Powerstroke)

Starting out as solid chunks of hardened steel, these have been bred from MPP's racing program, and the many they are involved in. MPP is taking all the data gathered over the past years to present real world solutions to this platform. These main caps are able to utilize stock configuration ARP main studs, as well as their street girdle, for the ultimate in performance and longevity. MPP started with a MUCH stronger material than OEM, provided much greater surface area contact than OEM, and the ultimate ability to be wrapped up tight with a bow using their Billet Girdle to ensure that rotating assembly stays right where it needs to be at all times. No more spun bearings, no more crank walk, just raw, unrelenting power, for a very long time. It is highly suggested to run MPP's Billet Street Girdle with these main caps, and of course ensure everything gets properly line bored before assembly!
