he bagged on that thing all the time and blew engines left and right because he ran it HARD, all he did to the rear was install a different diff cover that helps re-inforce the carrier bearing caps. a friend of mine used one in a turbo ls powered mustang with a 6 speed. they are easily beefed up if you think you need big power, check online there are lots of performance parts available. the 8.8 is a pretty tough rear and the flanges and drums/discs can be drilled for chevy pattern or whatever. Google ford 8.8 or go to 'the ranger station' for info.
