    I'm tossing around the idea of doing dual 241 t cases. Using a driver side front section for the front and tie it to my passenger side 241 rear. I think 5.44 low would work out ok but the problem is will the rear t case hold up? I am pretty sure the only problem might be the chain. Has anybody even tried this? Is it realistic to think it will hold up fairly well? My reasons for even thinking about this is because I can do it pretty cheap and it will be some serious low range.

    I'm having a hard time picturing what you are saying. I guess its to early or something. Are you talking about doing a doubler-type set up with two NP241 transfer cases?

    yes he is, there are kits to remove the chain from a 241 and run another case behind it. Personally I'd consider something stronger for the second case if you were to even consider it. Maybe a Dana 300? Then you have the option to build it up and use a 4:1 kit down the road for EVEN more low range?

    I have a round pattern 205 sitting in the garage. I just want to mess around with stuff I already have set up.

    That is an awesome idea! Never heard of that before. This place rocks.

    Not sure how you came up with that number. The t case's have 2.72 low so double is 5.44.

    I believe you multiply the two numbers, not double them.

    yes, you multiply the numbers... so its ~7.4:1.

    :doah: What was I thinking. I totally forgot to multiply instead of add. Anyhow 7.4-1 would be super low. I seriously think I'm going to do this and see what happens.

    Yes I have 1 in my dodge cummins/ats/241 But I think the 241 in that has beefier parts than 241 in the blazer.

    I run double stacked 208's in my "Marvzda"....

    The 208's are holding up fine.... But I think they are because I'm pumping 1.6 liter 4 cyl power thru them and the rig weighs 2k lbs...

    With a fullsize truck and even mild V8 power, I would bet on the 2nd 208 checking out early....

    Using the front half of it for a range box and a 205 downstream sounds like a much better deal... :waytogo:

    BTW.... I'm making an assumption that the strength of a 208 and 241 are pretty much in the same ballpark...

    as far as I know the critical dimensions of the 208 and 241 are similar. Dunno about the 241 HD though, I forgot about them being different in the dodges. :thinking: Wonder if they are beefier, other than the chain...

    Well I guess since nobody seems to have actually tired this I might give it a shot and see what happens. I believe the weak link will be the chain so I will pack a spare.

    oh I didn't realize you don't know. There is a guy on Pirate who sells kits to do it... He mainly uses 231s for the reduction box but I am pretty certain he uses 241s as well. Look in the Vendor's Section.

    And I must say Wayne, its not so much the chain breaking, but if it lets loose, the case is a goner. A spare case would be a better thought if you are really worried.
