    If a person like myself was to build a Transfer Case like the Atlas T/C what gear ratio would you put into it. It would be a 2 speed setup. Why can't you run a Atlas in a Fullsize? What breaks on them? Just looking for some information. Thanks guys.

    Well they get put behind V8s all the time. I think they are supposed to be able to handle up to 750 lbs/ft of torque. Alot of the jeeps they get thrown into arent all that light either. Should work just fine in a fullsize with a small block.

    Got this from the Advanced adapters site:
    The Atlas has been tested and proven to handle 900 plus ft./lbs

    the atlas was redesigned a couple years ago. its the old ones you cant use in a full size the new ones are fine. actually either of them will be stonger than just about anything stock fullsize or not.

    friends romans countrymen, lend me some parts

    Well there is a guy on this board that has a Atlas in his blazer and it seems to be working fine. I had a chance to look at the insides of a Atlas at High Country 4x4 in Denver and I was not at all impressed on the unit. Don't get me wrong, it is very nicely made, but the gears are way to small for a fullsize blazer or truck. The width of the gears are only .900" wide. Look at a NP205 and the output gear is 1.000" wide,but remember that you are twice as low as a 205. So this is why I don't think that you should use them. I just think a better case can be built. I am going to try and do it. It will have one large ass output shaft. So what gear ratio do you guys like or would like to have.

    Approx. 2.5 and 5.0 would be nice.

    You might want to talk to Dblazer I think he's running an Atlas II in his K5. He wheels his blazer pretty hard and it seems to hold up.
