Ford Dana 20 into a YJ?

I was talking to my buddy last night about engine/tranny/tcase swaps into my YJ for future mods. He recommended I look into using a Dana 20 t-case out of an older Bronco. He said it's a beefy case, it's got a d/s drop, and you can get a reduction kit for it. What are your guys thoughts on this? I didn't know they made it a d/s drop. Any disadvantages to it? Is it very long? Or short should I ask? THanks!

Are the Bronco D20's hard to find? I don't know much about D20's. They're pretty strong, right? I believe you can get a gear reduction kit for them also, can't you? What about twin sticks? Think they'd work good behind a 5.0/T18? Thanks!

Re: Ford Dana 20 into a YJ?

Are the Bronco D20's hard to find?
--not really they auto versions are getting rare

They're pretty strong, right?
--all but the 10 spline output, but that is upgradeable

I believe you can get a gear reduction kit for them also, can't you?
--ya, the tshift has 2.46 and the J has 2.3? you can get 4.86 for 1600$ and 3.?? for like 1000$

Think they'd work good behind a 5.0/T18?
--with the cost of the d20 strong output(500$) low gears(1500$)its not really worth it unless there is no adapter involved.

Most bornco users don't use the atlas 2 because of the expensine adapters, and most people don't use the d20 cause of the cost to upgrade.

I run a C4 and D20 without adapters. Some people may argue that the C4 isn't strong, but I've yet to see one explode yet. the dana 20 gearset is low enough for me and my 36's even though I will go lower someday. I always keep a spare output on hand too.

go to http://www.wildhorses4x4.com/
http://www.broncohq.com/rmtt-dana20transfercase.html

for more info.

Yes they can be twinsticked.

Re: Ford Dana 20 into a YJ?

Well, I wouldn't mind sinking money into it over a period of time. I just don't think I'll ever have $2300 ALL AT ONCE to buy an Atlas II. So I was thinking if I could find a beefy transfer case and upgrade as I go, that it would work out pretty good. How would the 20 compare to an Atlas? Thanks for you help guys!

the case is strong, the output is the weak link, so if you get a few spares or the HD shaft then your golden.
