I am thinking of keeping the np208/241 thing going until I can afford a single low case . No more thoughts of doublers . Perhaps an Atlas or comparable single case next year .
So should I sell my 205's ? Or is saving them for some future use stupid ?
I have a passenger drop Chevy 10 spline , and a drivers drop Ford 31 spline that I got for the input shaft .

Pauly...
I too, have a 205 collection that I'm not sure if I'll ever get to the bottom of....
Oh... and I found these in there too....?!?!
just kidding....
Anywho.... what would make you not want a doubler in favor of an Atlas or Stak?
For a Big Truck like yours, I think the Doubler is better cuz:
1) You can assemble it cheaper than A or S.
2) Your rig is not light...... so no need to go on a Transfer Case "diet".
3) Drive line angles work out better w/ the added length of the Doubler.
4) As fullsize guys migrate towards buggyland, you can scoop up a good deal on a Doubler while they bite the big $$ on A or S. [Bootieman and DJ may soon fall into this category]
To me the cheap/hot ticket right now is the 241 rockbox with a 205 behind it. It offers a 3spd case with 3 different ratios for wheeling. If you have a 241 & 205 that would work for the combo you are only looking about about $400 for the kit plus driveshaft mods & crossmember mods.
241 plantaries are pretty strong & a 205 is indestructable so you get a pretty bulletproof setup for a good price.

Andrew has been messing around with a prototype of his own off a 208 but I don't know how it is coming. He was just starting it when I talked to him a few months ago.

I was just looking at the dimensions of some things , and think I may want to get a Stakk . The rear shaft gets longer by a hair , which may help angle and get rid of the CV ( which I can sell ) . And my front driveshafts are easier to work with , as I can go 32 spline flange .
Which is cool , as I have several easily modified front shafts , and several non CV slip in the shaft type shafts like behind a 205 at home .
I know I should want a longer front shaft , but I haven't even broken a front yet . It seems perfect length for my lift combo at the moment . And its 24 years old original .
In the meantime , I think I am gonna box in my 208 crossmember so I don't bend it , and run a piece up front under my exhaust ( I hit it hard last week ) .
It will be a year or two minimum before I do anything ( Then I can sell my CV to some neebie with a shackle flip and vibes )

J.B. conversions makes a 4:1 now for 205's if you want to stick with a single case.i have the 4:1 and 32 spline outputs on my 300 and i'm very impressed with both.
Pauly, the 700R4 208 combo makes the front shaft a bolt in with the doubler. The STAK and alike will knock 6-7" off of your shaft.
Oh duh , my bad , yeah the np208 does go back a little bit from the mounting flange of the adapter . And the Stak is pretty much flat on the front .
I'd rather not move my exhaust .
Well , its all speculation right now anyway . But you all know from watching my progress that I will make it happen sooner or later .
So which combo would be good , heres what I have already :
Chevy 10 spline 205 Ford 31 spline 205 part time 203 with flat flange front output ( and a parts case with the same ) Full time 203 with a bad chain and u-bolt front output . 700r4 installed now np208 installed now
I have a spare th350 , but rather not lose my 700r4's first gear .

Keep in mind though that Fred gets away with alot because he has the drivetrain to flog the dog shit out of his truck without breaking it. You start gassing on 1/2 tons like he does on his 1 tons you will be replacing ALOT of axle parts. Big tires, beefy drivetrain, & low gearing allow Fred alot of leadway that smaller tires & weaker drivetrain won't allow you to get away with.
You will have to be careful on any route you choose with gearing that deep. It will make it alot easier to break things. You will have to practice good throttle control to keep breakage to a minimum. Fred doesn't have to practice good throttle control.
I really like the 241/205 setup because of the cheap factor & the range of gear options available.

I have a contingency plan . If I break the current 12 bolt , I am putting a 14bff in my tow rig , and putting the 14bsf in my Blazer . Stronger and six lug

Paul, the doubler is cool. But after all of the adapters are sourced, x-members, yada yada, it is going to be pricey. And 4:1 aint that low anymore. I wanted to go with a klune when I first made that step. They needed a longer lead time and I didn't want to wait. I like the 2.72 middle gear. It is nice gear for tooling and the extra low makes a huge difference.
The 241 planetaries are a hot ticket. That is basically the Goliath klune set up. If you can cut the chain box off of the 241 it is a bolt in for your current set up. The shafts will be close in length and you can adapt your CV to the 205.
Also, if exhaust is an issue, don't do any kind of t-case switch. It is too cheap and easy to modify to let it get in the way.

I have duals on my truck and I HATE it. It is always in the way and takes up WAY to much room. If you have/can find the right 205 to sit behind the 241 rockbox you can get double cases pretty easy since the 241 rockbox will bolt right up to the 700R4. Just have to worry about crossmembers, shifters, & driveshafts.
