Most Heavy-Duty Tranny/T-case setup for 4.0L

[BONES]

No the c4/c5 are early 80's at the newest and the 4.0L started in the early 90's I believe. The 2.9 is the same block from what I understand and it has a different bolt pattern than the c4/c5 applications. I could be wrong but the c4/c5 never came behind the 2.9/4.0 based block at all.

does anyone know if the c4 was ever even offered as a 4x4 tranny? that would save me some time. as of right now i dont think they did

I think the early broncos auto was a c4.

 

[BONES]

Yes only 4x4 C4 was offered in the early Broncos. Early Bronco was produced from 66-77.

oh ok. so if i was to find one of these all i would have to do is switch out the front bellhousing, unless i like the c5 options for transfercases better. i dont even know what that bronco c4 would take

quote=what the c4 would take?
Not sure what your asking here.

Yes to the bell housing change, because the Early Bronco 4x4 c4 never came behind these v6's. Far as I know the Spicer/Dana 20 is the only tcase that bolts to the 4x4 c4 (28spline output), unless you get the tail shaft and housing from the c5 (25spline output) then the 1350/1354 will work.

i was refering to what tcases the bronco c4 would take. ive been looking at the 1350/1354 doubler build and i really think i could do it. i got plenty of time its not like the splash is going anywhere. i think im going to keep close eyes on the classifieds and eventually come up with a c4/c5 combo. this would eliminate having to shorten/get new driveshafts. it really seems like the best option.

I know hey, there really is limited choices on what will work with these trans. At least without spending a ton on custom parts.

yea man no joke. those adv. adapter setups are crazy high like a good $500. i dont have that kinda money. it sucks cause i have a hard time putting this time and effort into all this for a 4 liter. i want a 351 but i dont have the materials or the right place for that right now. do you know if the c4 bellhousing will mate to it. that way i can have a built c4 that would be as good as a stock c6 when that day comes. thats if i get the bronco c4 i guess unless all c4 bellhousings sre the same, that does make sense. then i can swap the front bellhousing when ever the v8 comes around

That is an option I'm looking into. There are kits available to put the low range box from a 203 t-case in front of a Dana 20 t-case. You can also twin stick the 20 and or install a low gear set.

Just more options with the EB C4/D20 combo than a RBV C5/1350.

 

[BONES]

Do you have a link to these 203 kits for the C4? I'd very interested in this please.

My 4x4 C4 came from a v8 early Bronco, came with v8 bell housing factory, unfortunately the guy I got it from wanted to keep the dana 20 and adapter.

 

[Bent Bolt]

Yup

OK cool, thanks for that link man, much appreciated!!

You know I looked and looked, I found specs on the c4-203 adapter length but no other info on it or price. The link you provided was all manual trans applications.

I know it's going to cost 500bucks or more for the kit and I'm not spending that unless I can get a doubler out of the deal at the least.

I actually just need the intermediate shaft if they sell separately. They have the 10 spline c4 to atlas intermediate shaft for 150$, I hope they do have the c4 to np203 intermediate shaft separate. It says they use the Dodge 23 spline tcase in the manual trans set-up's, but either way, this may work out to be another option.

I would love to end up doing an np203/205 doubler behind the c4 if this pans out, Think about it for a second, my set-up, fm146/1350, is roughly 40 ish inches long and the c4/203/205 would be only a couple inches longer at 42" and the c4/d20 is 35.5" long.

The c6 is so much longer (27") than the c4 (17") that I wouldn't have been able to run the 203/205 doubler and still have a long enough rear drive shaft....... I hope, but I'm not holding me breath. lol

I contacted them through email to find out more.

yea man thats what i'm saying. if im spending 500 on an adapter kit i might as well get an atlas case and some currie built axles to ice the cake (sarcasm), but no i want 500 to put it all in the truck lol.

What i want is a business that will make and sell the sector shaft thats one piece not two pressed together. id be willing to pay up to $200 for it cause thats the hardest part i feel like. i've heard of d.d. machine making them but i heard he is real bad at getting back with you and with delivery times.

a 203/205 doubler behind a built c4 would be sick too.

I picked up a well abused 84 BII today that has the fabled C5. $100.00
I'll still use the 1350 for now but I can upgrade to a D20 or Atlas in the future easier now.
