It's been 5 years since we first started this chat. Has ANYONE heard anything different as far as getting some gearing into the 80?

Yes its called an atlas 4 speed transfer case Atlas 4 Speed Transfer Case Builder | Advance Adapters
Absolutely is a way to make it work with the 343f. Buy yourself the output shaft and tail housing from the AW4 Cherokee auto. Swaps right into the a343f (requires a tear down to swap), and then you can use any one of the clockable novak, aa, etc adapters for an AW4 to a dana 300, atlas, etc. Dana 300 (super light and strong, lots of upgrades, 4:1) would be an awesome swap and half the price of an atlas.
Has anyone done this swap?
Love NWF.
It's on the website but they don't have anything available yet that bolts up to a stock 80-series. It's been 'in-progress' for 4 years.
pfffttt. That blows.
Do they at least have input and output shafts that match up? Lets make a CAD file for some adapter plates for this thing.
Or we should call and ask them whats available, and then mention that advanced adapters is going to do a run of input and outputs for a 10 order group buy... just to put some pressure on them.
I know that there is someone running the NWF doubler on their 80. Pretty sure I saw it mentioned on Pirate, but, I can't tell you exactly where. Not being able to run a doubler was one of the primary reasons for me getting out of the last 80 and back into a 40. The lack of gearing makes for way to exciting (read body damage inducing) wheeling in the big pig of an 80 series.
Huh, well thats too bad, hopefully you enjoy the 40 no less.
Just my opinion, but if anyone had their heart set on a doubler, they should just make it happen. Maybe that sounds flaky, but we can get shafts made or cut and splined (see the NV4500 HF2A adapter thread), and we can certainly get adapter plates cut to mate them up with some time measuring and scratching together what you need. If I had a need for one and my mind set to it, I'm sure it could happen. There may be a whole bunch of collateral changes, fuel tank, driveshafts, suspension etc, but I'm sure it's still possible.
A person can certainly make it happen, but being that person to do the initial r&d, go through a few incorrect parts to the tune of a couple thousand dollars isn't in the picture for a lot of folks. Personally, I'd rather go with something tried and true and put my few thousand towards having it done correctly the first time.
I emailed NWF to ask, they're response:
Cody,
We have cases and outputs to work with the 80 Series Transfer Case.
The Adapter to go to the Transmission has been designed we just haven’t been able to get input shafts made yet.
So far they are only available to mate a 80 series Case to a Domestic Transmission.

I need to ask more about what they have for input shafts.
Perhaps we should be considering a swap to a different transmission to allow the NWF doubler and the HF2A / HF2AV case.
Edit:
I sent an email to ask if they would sell the doubler (ecobox or blackbox) with the adapter for the HF2A, and if we could order a "blank" input shaft with it, to get it cut/broached elsewhere to fit, also if they would sell the trans adapater.
Alternatively, if the A440f trans output shaft is the same as the H55F, we could take the input gear hub (female splined input) of a split case, cut it down and mate to another cut output shaft to feed the NWF blackbox, based on whatever options they have for inputs into it. Just the adapter would need to be longer as it would have a spud shaft between them, but could basically be done. I will let you know what I hear from them.
Heads up, this will likely interfere with your fuel tank though.
This just moved forward, maybe millimeters, maybe an inch even.

And another email back from them, they don't want to sell anything without testing it first and don't know when they will get around to making the input shaft yet.
Anyone know of an place to "Start with a 21 Spline Jeep Input and have it Wire EDM’d to the correct profile" as per the last email I recieved from them?
Also per their email:
"No Parts are leaving our Facility until we have had a chance to bolt everything together to verify everything works the way it would, we have been burnt in the past sending parts out before we have a chance to do our test fitting."
This just moved backward, maybe millimeters, maybe an inch even.

Understandable. The potential risks of selling untested parts far outweighs the measly couple of bucks from trying to make a quick sale. Can't fault them for putting quality first.
I agree. Can't argue that.
Reality is... If as per above, they've been working on it for 4 years, it aint gonna happen this year either. So if anyone really wants to move forward, I don't see waiting on NWF helping. Not trying to knock them, its just being realistic.
Having said that, I think that it could be made to work still. Spud shafts can be made, so can adapters plates without them. I am not needing or interested in having an NWF box, so i won't have one in hand to work with, but someone else here should certainly break new ground. I emailed them to see if they would at least sell the box with an HF2A shaft on the output side of it.
I guess this is the final option, from NWF (Kris):
"Right Now we can do Domestic Transmissions to 80 Series Transfer Case, 60 Series Transmissions to 80 Series Transfer Case, Domestic Transmissions to 60 Series Split Case and 60 Series Transmissions to 60 Series Split Case. "
So you can run a doubler and split case or HF2A. But you have to put a domestic trans in front of it.
More info related to the topic:
"
Products don’t get designed over night, and when custom gears are involved it can be a very lengthy process. We have sent the Splines for measuring to 4 different shops now all saying they could measure it and create a profile to work with and each time after waiting months thee send it back saying they couldn’t do it. I just shipped it agin to another place with a 3d scanner that thinks they can create a profile that way, we will see.
The 80 Series is a good market and we fully plan on completing the project but its not our number one priority we have to keep the shop doors open producing the parts we already manufacture.
Honestly i have only had a few people ask about retaining the Stock Transmission most guys buy this as an adapter when doing say and LS swap and want to use the GM Transmission. From the 80 Series Owners i have talked to alot of guys are interested until you mention gas tank relocation or modification. Alot of them are not will to get that crazy with their builds."
Did they specify what kind of modification would be needed to the gas tank? Seems like a little bit of persuasion with a hammer could do the trick.
No they didn't, I don't think they would want the liability of describing the work involved. Understandably neither would I.
We do need someone to move forward with this, and either define what hammer work is involved, or find a shop who will do the mods and let us know the cost and contact info.
I guess if someone wants to swap a manual anyway but retain the AWD/4WD it is totally an option. You'd need an AA adapter for the trans and maybe to mod the fuel tank regardless.
You seem like a fella who gets things built... How about a 5 speed transmission, doubler and an HF2A?
