transfer case

[kman458]

i am starting to get the drive line parts to get the cherokee up and running. i have a d20 and a 300 transfer i can use. which one would you use. it is going behind a 383 sbc/ 700r4 or maby 4l60. it will also have 44's for now unless i stumble across some 60's in the mean time as well as 38/15.5-16.5 ssrs. i will use this mostly as a spair run around town/trail runner.
thanks

sounds like you've got a sweet setup Kenny. I'm by far not a TC guru, just thought your post could use a boost smile.gif
I think the 300 has a lower range than the D20 fwiw.

thanks gawdzilla i hope it turns out well.

what no one has anthing to say about this.

Personally I would go with a NP208 since they are a Dime a Dozen and bolt up behind the 700R4. If you were to stay with the TH400 then a NP208 or a NP205 would be my choice

By the way nice Combo and good luck, I love them 383 SBC ;)

300! Lower low range than the 20 (somewhere along the lines of 2.6:1 VS. 2:1) and it's all gear driven-no chain to worry about! No brainer!!

No brainer!!Except for the weak output shaft, though I have no experiance with the D300, its reputation advertised by those that put them between power and big tires is what kept me from using one. While I have done everything imaginable to a NP208 and never had a problem, and the NP205..........Well its just STRONG! LOL.

Them desert racer chevy folks been running the piss out of those 208's for years now.
Got to be some method to their madness smile.gif

if you can find a 208 with the correct drop, go for it.

but since you have the d300 on hand, and it'll bolt up to the NP pattern, it's almost a no-brainer. you can get kits to strengthen the ouputs (really the only weak links, since they are aluminum.

if you want a truly strong tcase, look at a NP241. awesomely strong case, good low range.

thanks for the input. i will take a look at a 208. i thought i would stick with what i have on hand now and that would be a 20 or a 300 and there is a 203 in there somewhere.

[Crazy_Jeepman]

203 just sucks you do not want that. I was wondering if the D300 even bolts to the 700R4 without any big $$$$ adaptors? I can't think of anyway to make a D20 bolt to a 700R4 either. If you are going to try to use Adaptors to do it then I think you would be better off using what came naturally behind the 700R4.

Well then there is this option, since you have a TH350 version of the NP203, and that will bolt up to the 700R4, so then all you would need is................ THIS!!!!! (http://www.offroaddesign.com/catalog/doubler.htm) :D :D

[kman458]

i have read about doublers but had not really thought about going that way. i thought it was mostly for the crawlers. i will look into it.

I would go w/ the D300 since you already have it. The only weak link is the rear output, and they make 3/4 ton conversions for it.
I think you'll need an adapter to make it fit the 700r4, or you could always sell the 300 and get a 242 out of a hummer. Tough as nails and they have the 2.6:1 low.

What tailshaft do you have on your tranny?

The D300 has a 23 spline input and a chevy tailshaft has 27 splines (usually). The dana 20 has 10?

You're gonna need adapters or use a chevy x-fer with a 27 spline input
