Does any one know the low range on the NP 208 t-case? I read that the NP 208 would bolt up to a zf trans with a kit from advance adpaters, is anyone familiar with this? I was also told that the np 205 was much stronger and would be a better choice, is there any way to bolt up an np 205 to a zf? Thanks for any feedback.
the 205 is a lot stronger than the 208, a 208 is an all time 4wheel drive t case. i found a 205 in pa for $150, im about to order a 205 for that same price from someone else in pa. the guy with the 205's e mail is chilly460(No Email Addresses In Posts!). im not sure about all the bolt ups though.
Thanks a lot orange peel. No one seems to know anything about transfer cases for Big Broncos. Sounds like the np 205 would be ideal, this may be a stretch but have you or anyone else for that matter, ever heard of going with dual np 205 t-cases? Is it possible? I am looking at a zf tranny in my bronco and since I have to get a new t-case anyway I want to upgrade my t-case strength and low range if possible, but I'm on a budget of course, so no Atlas II t-case.
Thanks.
http://www.offroaddesign.com/catalog/doubler.htm, thats the url for the place that makes a dual t-case kit, my friend is gonna do it to his truck, not sure if im gonna do it or not though. that site tells you what all needs to be done.

The NP205 is a gear driven case. The NP208 is a PART-TIME, chain driven case. The 205 would be the way to go if you are going to do some heavy wheeling.
Kerry is right, the 208 is a part time case. It's also aluminum and about 50lbs lighter than the stronger, cast-iron cased 205. The low range on the 208 is 2.61:1, on the 205 it's 1.98:1.
Thanks all for the replies. The np 205 sounds like the way to go but does anyone know if the np205 will mate to a zf or if there is an adapter kit available? Has anyone heard of this? I read quickly in the new Petersen's about the f-150 on the cover with an np205 bolted to a c-6 and then doubled again through an np203, is anyone familiar with this? How much work is it? Thanks again for any responses.
I just read the article that orangepeel listed so I guess my last post about the np203/205 is not important, but what about mating either of those t-cases to a zf? Anyone have any ideas? By the way does anyone know how many spline an E40D output shaft is? Thanks for the help.
The ZF has a round 6 bolt pattern and a 31 spline output shaft (I'm assuming you are talking about the 5-speed).
NP205s came in a bunch of different trucks with different input/output shafts, and the earlier ones even used an oval 8 bolt pattern (GM). If you find a "Ford" version, it will have the same 6-bolt round pattern and a 31 spline shaft that will match the ZF.
Factory 4x4 versions of the E4OD also have a 31 spline output shaft and the same 6-bolt pattern. E4ODs need the factory computer to run... something to think about.
Everything should just bolt together, except I'm not sure about the lengths of the input/output shafts. You might need a simple adapter plate (spacer) that any machine shop should be able to fab. The tail housing on the ZF will interfere with the 205 shift rod, I know a guy who just ground down a bit of the tranny case for clearance (don't recall if he had a spacer/adapter). Also, the ZF uses a hydraulic clutch, and the 205 is HEAVY, and probably will require some kind of support.
