I know a guy who used one of these in his rock crawler. I don't know much about them other than they did come in 3/4 ton pickups and up. Correct they are factory 4.56 gears, and from what I recall he had a hell of a time locating pinion bearings for it, or they were extremely expensive, I forgot. But that is a BAD A$$ rear end my friend. Wouldn't necessarily put it in anything 2wd but definitely a 4wd beast. I'm sure there are plenty of people on here that can tell you more.
