Atlas II Transfercase

[Shaggy]

I just started looking for transfercases for the bronco and I am thinking of ordering this one.
Atlas II (http://eshop.advanceadapters.com/commerce/catalog/productmisc.jsp?product_id=2370&czuid=1096230313328)
I don't know a whole lot about it yet. I have some questions that some of you might be able to answer. Will this bolt to my transmission without an adapter? Will this reduced transfercase gearing be enough to make up for running 39.5" tires with 4.10 gears? Does anyone know any other companies that might have them at a better price?
These are all the questions I have right now.

[bburris]

If you buy one you can get a much better price through one of their dealers. If you're not in too much of a hurry wait for a vendor on Pirate to have a sale on Advance Adapters stuff.

What transmission and t-case do you have now? That will make all the difference on whether or not an Atlas will bolt up or not.

You're low range while off-road will be much improved, but you won't notice a difference if you plan to drive the Bronco around town. With 4.10s and 40s it'll probably be a dog, but off-road you should have much more control with a 4:1 low range.

As an example of the difference a 4:1 low range makes, Blake (buddy here) has a 4cyl in his YJ with 42s and a 4:1 kit in his NP231. It can't go more than 45-50 on the street with 5.13s, but he still has a whole lot of control over everything when he's off-road. I think it's actually better than when he had 4.56s and 35s, because it would actually go too slow at times on 35s and he had problems with his tires scooting on downhills (not wanting to go fast enough). Now it seems to have evened out some.

i currently have a c6 and 208

[AgDieseler]

You might consider a Klune V in front of the 208. It's not a weak t-case as long as it has plenty of skid plate protection, and therefore never sees a hit from a rock.

An atlas is very nice, but I would think that more low range options would be a nice thing - dual transfer cases.

[CRaSHnBuRN]

would it be possible to swap out the 208 for a NP203? Then you could use something like a ORD or stazworks doubler to run a NP205 behind that. That would give you more gearing choices (1:1, 2:1, 4:1). Plus they use easy to come by OEM parts, and can be done much cheaper than the atlas.

[Shaggy]

well i am not against doing dual cases but i dont know which ones would be best... i also have the transfercase out of that f350... not sure what it is... what i do know is that the 208 is chain driven and i have heard chain cases are hard to do dual cases with and i am curious as to if i can do it.. i have heard that the 208 is pretty strong but it its gearing is only like 2:1... does anyone know what transfercase i have from this 92 f350... i could go look but it is covered up in storage by lots of stuff

[AgDieseler]

208 is 2.61:1

[StevenAg03]

the 350 will have some sort of borg-warner t-case. i would be careful with too much gearing and an auto. might be kind of hard to stop it if your brakes arent perfect.

[bburris]

I think swapping a 203/205 doubler would probably be your best option. You can find whatever NP203 and a Ford NP205 and run the ORD Doubler kit. That way you'll have a 2:1 low range for normal train riding, and a 4:1 for crawling like you'd have with the Atlas.

[Shaggy]

i was just looking at the klune v as well and that might be another root... but i dont really understand how the shifting works in them... does it have a separate shifter and you would still have to twinstick the transfer case separately... from what i know you cannot twinstick a 208 becase it is chain driven... one of the goals other than gearing i want out of this project is twinsticks... i watched troy using the twin sticks in the comp last weekend and was sold on it...
from what i could tell with a klune v i could get even lower gearing than an atlas and still be able to use the higher low range... they appearantly have the same bolt pattern as the 208 so no adapter is needed but if i went to a 205 and had to twin stick it this would be more expensive than just ordering an atlas

[stx4wheeler]

tate you can dual case the 208 there was a guy on pirate i think that did it a month or two ago or either a 1356 borg warner case i dont remember, which might be the one outta the 350, you can buy a 205 pretty cheap, and twinstick it pretty cheap as well,and the 205 is gonna be the strongest out of all of those 3 cases.

[bburris]

The Klune is shifted as a seperate range box. All you can do is select high and low range with it. That's the same as you would accomplish with the 203 range box in a 203/205 Doubler.

The difference is that with the Klune you will only have lots of gearing choices. With a 203/205 Doubler you will have similar gearing choices, but you can modify the 205 to work as a twin stick (you can shift high/low and front/rear) like an Atlas.

You'll have a much shorter driveline with an Atlas, but you get an extra gearing choice with the Doubler setup.

[AgDieseler]

The Ford 208 and 205 is a five bolt pattern, so be careful what you try to put together. You're right, a chain case can't be twin sticked. The Klune V is shifted by a seperate shifter - either cable or hard mount.

If twin sticking is that important to you, than look into a doubler. ORD has some great customer service, so just give them a call and see what can be made.

Here's the doubler page:

There's a guy in the vendor's forum on pirate that sells doubler kits pretty cheap. I think about $450. That's just for the adapter.

[Sharpe]

With the ORD kit you could Triple Stick it :gigem:

[Shaggy]

i read about that earlier... what can you do with a triple stick that cant be done with twinsticks

[AgDieseler]

Triple stick comes from having a twin sticked 205 plus a 203 range box. You can run front in 2:1 lo or 4:1 lo. Once again, more options.

[Shaggy]

ok i get it

[CRaSHnBuRN]

the vendor that eight mentioned is stazworks.

http://www.stazworks.com/doublers.html

ORD has a good product too, but last I checked they were still quite a bit more than the stazworks one.

The prices is pretty good, and its clockable for a flat belly. Its gives you the most options, and is relatively easy to do, versus the klune, which I have always heard can be kinda tempermental to get lined up right.

[Shaggy]

should i spend the time searching junkyards for a 203 and 205 and rebuild them or should i just try to find some online that are already rebuilt

[Shaggy]

this is a pretty good website i found that has specs on a lot of transfer cases
http://www.offroaders.com/info/tech-corner/facts/trans/trans.htm

[fbronco86]

does anyone know about how much just that shaft would cost to make? I have all the stuff to make a doubler but i am cheap I can make everything else but the shaft.

[CRaSHnBuRN]

do a search on the yota part of pirate for D300 by DSI. He built a home brew yota to d300 adapter, and built his own shaft. Perhaps that can give you an idea of the price and where to go to get it done.

As for rebuilding the cases, to tell you the truth, I wouldn't really bother unless there was major signs of leaking or something. Both of those cases are pretty strong, and you're junking the only real weak link on the 203, which is the chain drive in the back of the case. I've helped swap several of these into different trucks, and never rebuilt a thing, and they run fine. Junkyards or swap meets are great places to get these things. What kind of prices are you looking at for a rebuilt one? The biggest concern is what is it gonna take to attach the 203 to your C6? Was it a factory option?

[bburris]

I agree about not rebuilding it. If you find one that is out of a wrecked vehicle or one with a blown motor or something you'll be fine. The seals are the only things that might need attention, but I doubt many people even change those.

[Shaggy]

im not sure what kind of adapter it will take to put a 203 on a c6... i guess i need to look at that too

[BigRedFord04]

i put together a 205 and 203 with a triple stick from ORD when i worked at Vilas. it was definately bad arse, i wanted one. you should have plenty of wheelbase to keep angles down right?

yes, rebuilding them is a pain...pull it and run it, change the fluid if you think its needed. people dont run them b.c. they're pieces of sh!t that need to be rebuilt all the time.

[Sharpe]

If it were me I'd rebuild them if they aren't in imaculate shape. I know it would be a pain in the ass and more expensive, but most of the 203's and 205's I've seen have been in poor shape, they're just so old. I just think it'd be easier to do it now than a few months or years down the road.

[Sharpe]

Here's a writeup on the ORD doubler

[Shaggy]

thanks but i too can find sites that come up in the top 5 in google search

[william_ace]

i think he might have been just tryin to help out

[Shaggy]

i know but i too am not retarted... he should have figured i have done some research

[Sharpe]

I didn't do any research to find that. That website is my main source of info and I just knew about the article anyway and firgured you'd like to see it.

[uglyota]

so what kind of painkillers did they give you? ;)

[fbronco86]

I would not rebuild them unless they dont work. How many broken 205 have u heard about?

[Shaggy]

so what kind of painkillers did they give you? ;)
hydrocodine bt it doesnt work

[usmcagg02]

hydrocodine bt it doesnt work


drink a beer or two with it and it will :gigem:
(not that i speak from experience or anything :D )

[uglyota]

I don't think he's gonna do that

[usmcagg02]

prolly not but it worked for me

[uglyota]

just striving to promote the warm and fuzzy, supportive TAMOR :gigem:

[AgDieseler]

I can still hear the surgeon's words ringing in my ears...

Me (slurring from the anesthesia): "Hey, Doc. There's a batchelor party tonight. Am I cool to go?"
Doc: "Um, yeah, but don't drink. Vicatin plus alcohol will do some nasty things to you."
Me (still slurring): "......sweet."

Turns out, the batchelor party was a no-go, and I have leftover Vicatin for sale. :laughing:

[Disclaimer: The preceding message, while containing drug references, in no way condones the abuse of controlled narcotics. In fact, there is no Vicatin for sale.]

[Shaggy]

i actually have drank after taking hydrocodine and it does make you pass out... but as i dont drink anymore that is all in my past... becides... the pain isnt too bad... for i am no *****

[Shaggy]

i am putting together what i need to do my np203/np205 setup and i need to make sure this transfer case i got is indeed a ford np205... i am pretty sure it is but it has no tags... i also still need a np203 gearbox

[Shaggy]

well i have come to the conclusion that it is indeed a np205... i just dont know if it is a ford one or not... im not sure if that matters yet either

[CRaSHnBuRN]

Here is a dumb question, but its a driver side drop right? If so, it has to be a ford in my opinion. Chevy and dodge had passenger side drops until chevy did away with the straight axle and went ifs, and dodge changed when they went to the last ram body style. At that point they both switched to driver side drop, but started using NV cases. I believe driver side drop 205s were used by ford. How about a pic of the thing?

[Shaggy]

i guess your right

[Shaggy]

[Sharpe]

Judging by the shift rail and PTO cover, I would cast my vote for driver's side drop. Is it supposed to have anything else on the front?

[Shaggy]

i know it is a driverside drop np205 and i didnt realize that ford was the only ones that made the driverside drop so i guess that it is a ford

[J Cooper]

i have a driverside drop ford np205 here at the house if you wanna compare them... i could go take a few pics for you if you want

EDIT: i may have read that wrong... i think tate was throwing down the sarcasm maybe cause i thought a 205 was only ford.....

either way i have one that needs a home
