thats why I'm feeling the need for a real crawl ratio in the transfer case(s) if I'm keeping the auto, otherwise I'm afraid it will hook up and jump foward in a fashion I won't be able to keep under controll.
with the np435 I could probably keep the stock transfer case gearing, still would need an overdrive unit though for highway speeds
The ratios of the ZF6 would be awesome, but would limit your options for cheap double transfer cases with the 4wd version. It has a larger output shaft. A 2wd trans and divorced setup could work. But I'm not sure if there is a 203/205 doubler based off of a divorce mount 203. It may work, assuming that the married and divorced 203's are identical where they attach to the drive section. The problem I would have is that extra long front driveline.

The TC allows you to cheat a bit with higher gearing, but they tend to build a lot of heat in the transmission by doing it.
so dragging this back up and dusting it off, cause my tax check is in
I'm down to two options, I have a line on parts for both right now
e4od-np203/205 doubler
c6-bw1356-gear vendor(maybe in the long term divorced np205for doubling)
seems the advantages are:
e4od I'll have a lot easier time getting the double low for wheeling, and lock up converter
c6 might be more reliable and with my injection pump letting me turn 3500 i'll have over second for steep hills
costs are likely to be
e4od tranny $500 controller $800 check and replace week parts??? any driveline mods or is it the same length as the 4x4 c6? down the road probaly $4-600 to build the np203/205 doubler box up and replace driveshafts
gear vendor $1200 for complete setup used with drivelines, same $4-600 likely for finding a divorced np205 and custom driveshafts
What are you going to be using it for? What size tire are you planning on? Axle ratio?
Unless you are going to be doing some extreme rock crawling with your diesel, I would spend your money on an overdrive and forget about doubling the transfer case. With the right gearing and an OD automatic, there aren't many trails that you can fit on where gearing will stop you.
its not so much gearing will stop me that I worry about, as lack of gearing leads to more breakage, especialy with an auto as I tend to get an undesireable ammount of wheelspin every time they break loose. nothing snaps axles like smoking tires catching on something sudenly.
I'll most likely end up on something close to a 35" tire at stock ride height with a body lift and some fender clearancing though a dana 60 front and small lift is definitly a posibility if I find one cheap
and as to use I like to claim I just keep a 4x4 to get to the better camping and fishing spots, but that being the case I often don't have another truck along to help me get out, been some long walks due to breakage, so i move real slow and carefull and value controll over abosolute ability.
I would invest your money into a rear locker before a second transfer case. Without traction at the wheels, the tires will still want to spin.
And there is more chance for breakage with more torque multiplication and a lack of traction. You will be amazed at how much farther you can go with just a rear locker.
With 35's and a Dana 60/ 10.25, you're not going to have much problem with breakage as long as you keep the maintenance up.
