crawler boxes
Has anyone ever mated a 203 range box to a BW-13xx box? (you know, like a 1345 or 1356).. I think the 205 has the same adapter has the BW, but I'm not sure. I think it'd be nice to have another 2:1 gear reduction + the 2.7:1 on a BW. I'd go with a 205+203, but I have no use for twin sticks, at least yet.

I was looking up at the Offroad Ulimited site to find out the same thing once. I did find in that site that there adapter will work to mate a np203 to any transfercase Ford uses. Or thats how I interperted it.
I looked on the website again but I did not remember where I saw that disclaimer in their site.

I am running a 203/205 doubler. I want more strenght over super sick low gears. I have hammered on it pretty hard and everything is holding together so far. my doubler adaptor was also alot cheaper than AA's is.
what are you doing that your going to need more than like 120:1 for?

I'm not sure exactly how much space you'll have with the 203 box bolted to the 205 but I'd imagine you could leave the stock single stick shifter on the 205 if you wanted. You will, obviously, have a second stick to operate the low gear on the 203. Maybe Jopey can tell you if the 205 needs to be twin sticked for the conversion. In any event it takes less than an hour to do with basic tools. You may just need to rent a back to move the damn thing.

well, I like to go really slow, and sometimes 2.7:1 and a 6.7:1 low gear isn't slow enough . Seriously, I don't know if it worth it to find an NP205 to swap in. I don't know if I could actually find one around here.. it'd be nice..
jopey- which adapter did you use? the one that dude sells on pirate?

don't know what type of vechile your putting the doubler in but in my 78 bronco a 2" body lift would have saved me alot of cutting and chopping. just simply fitting the cases in there was extremely tight.
If you use the stock shifter for the 205 it may not clear the 203 and adaptor housing.
I made some shifters similar to the ones that ORD has for sale for the chevies.
if 2.7 and granny low are not low enough so your thinking the 203-205 doubler is not going to be low enough you need to get your diffs alot lower than they are right now.
I am running the 435, 203 - 205 doubler and 5.13's in the pumpkins for a 137:1 crawl and it idles over just about everything in sight.

I'm going by my beater- it has NP435+NP208+3.08s+29" tires. At idle, it was going a little faster than I wanted it to when I was crawling up between these two trees on a trail I was on a couple weeks ago. [3.08 gears suck, but unfortionately I haven't had the time to switch out the locked 3.50 geared 9" for the 3.08, and I have to find a front pumpkin too). I'm not afraid body damage with the beater, I just don't wanna bust out any of the taillights or mirrors
However, the doubler would going into my F-250. It has a C6, which would probably work a lot better with the 4:1 gears. However, depending on how I feel, I might swap the C6 for the NP435, and I really doubt I'll have gears lower than 4.88s in it.

Right now I'm trying something along those lines, but going the other way. I'm doing a setup to put a 208 infront of my 205. The way i have it figured the 208 has two weak points: the chain and the THIN front output housing. If I eliminate them both and only use the planetary assembly it'll still be plenty strong. All I need to do is have the output shaft for the 208 shortened 1", seal the case where the front output housing is going to be removed, and then do up an adaptor. I figure i'll have about a 115:1 low range for under $200.

Don't worry about that chain. It's actually purty dang strong, just not as totally bulletproof at a gear-to-gear. Just make sure that it remains unaltered, so it can be changed out if something happends to it. Honestly, I haven't ever heard of the chain breaking, it's usually either the case or, I think it's a planetary gear that goes out, and warrants the entire T-case unusable.
