94 sas

[foodstamp]

ive been looking over sites the past 2 days about the sas swap, and their is some things i dont understand.

so i gues im going to use 50" springs, but which ones? do they come stock under the front of a older chevy, or what

and the axle... do i really want to change my t-case, i have a 700r4 tranny mild shift kit. and i heared that if you changes and mix match parts, the speedo wont work and the tranny wont shift right. i want this to be street legal, so can i use a ford d 60 axle sence their driver-d?

my truck is 6 lug, and i have a set of tire that are new, mounted on these weld racing rims, and i have another set of nice aluminum rims that are 6 lug, where im going with this is, is their a 6 lug d-60 or do i have to shit can these rims and get 8 lug?

will my stock steering box and pitment arm work?

[just4cuz]

What are you generally gonna do with the truck? I see you have the M715 which is plenty heavy duty. Do you want this truck to be comparible strength wise but have more creature comforts? If so then the 3/4 or 1 ton running gear is in order. If not you can get by with half ton stuff, but the factory rear axle will be your first weak link (unless you have a 14 bolt semi floater).
Personally if I was going to the trouble of doing an SAS on my truck, I would go with the big stuff. The 6 lug wheels will be easy to sell and with gas prices like they are I'll bet you can find some nice 8 lug stuff for sale cheap.

[foodstamp]

i just want it to be a truck that can go on/off road, im not going to beat the hell out of it since its my daliy driver, but the way the front is right now i dont like it. its not bad, but i just want something more off road looking.

my truck is a light 3/4 ton, so im not sure what axle it is, but i know its a 14 bolt, and it has a limited slip and i think 4:75 or something odd ball like that stock.

i want to keep the 6 lug if i can but if i cant it dosnt really bother me because it would be stronger...

is their a dana 60 6 lug on fords? or is their another axle i can use that would be better and i wouldnt have to change out my t-case

i want a practical sas swap that looks as bad ass as BGGRNCHEVY's truck

[ljhasaz71]

If your worried about the cost of new wheels than this swap isn't for you.

[just4cuz]

Your light duty 3/4 ton is a semi floater 14 bolt. Gear ratio will be in the paper glued in the glove box. It will be a G-- (a GT4 is 3.73) G80 will be your limited slip. If you want to keep the six lug and trans and transfer case, get a Dana 44 from a Ford full size, cut all the brackets off it weld on spring perches and convert the hubs to six lug. I do not remember if you have to change the the spindle but you need the Chevy caliper bracket, rotor and hub. No Ford does not make a six lug solid axle front end. Their six lug bolt pattern is on the IFS stuff just like your truck is now. Why would you want a truck that looks bad if it isn't?

[PsychoticDeadGuy]

Just go down to PnP, find you a D44 from a Furd, swap out everything, spindle on out fron a Chevy and you should be able to walk out of a PnP for under $150. ORU makes a kit to swap this axle under your truck, and they use a super common ??-88 (Dont remember when they got rid of the shorty springs) K5 and Suburban front leaf spring. Or you could fab it all up yourself. I am going to be doing a SAS on my '05 Duramax in a few months or so with the ORU kit and a Furd axle...

[foodstamp]

ok, cool thanks... no ill convert to 8 lug i wanted some rock crawler rims anyways, theirs 95 cal trans dually that ive been eyeing the axle for my 715, but i think that if i take off the spacer on the rear it might fit under my chevy right? then ill get a ford axle... my friend has a farm with a bunch of trucks, and i usually buy stuff from them all the time. next time i go out their ill have to start paying more attention and look for a 60 front on a ford... their mostly f250 and f150...

ill just start collecting parts as i go.

The f150 may have nothing you need (it could have a pre TTB solid D44 but some years had those funky C-bushing/coil mounts cast into the axle tube), the F250 will have the D44 leaf sprung....it may have a D60 if it was the snowking or some "package" like...or all "F250 Highboys" that IIRC, the d60 were generally specific to F350's....it sounds like, from your description, that you could use either a D44 or D60....whichever you happen upon 1st.

You could use a more common GM D44/10bolt or GM D60 and swap to a late 80's to early 90's NP241 drivers drop T-case if you find it difficult to obtain a ford D44/D60 without paying thru the nose for one. You'll just lose the "4X4" indicator light on the Tcase floor console.....I believe that is all you'll lose. I was thinking of that with my '94 K1500.

[foodstamp]

ok, thanks...a 44 would probaly work fine.

if i can get my hands on that dually rear end would that be good? its a 8 lug floater, then i can take the spacers off right?

then grab a 44.... im going out to the farm in a couple hours hopefully, ill try to rember to grab a camera...

i was checking out the paper in my glove box, and i gave up, theirs a ton of numbers... ill look later on

[rcurrier44]

Personaly I think you are way over your head but I will try to help out with questions others have missed.

so i gues im going to use 50" springs, but which ones? do they come stock under the front of a older chevy, or what

There is no 50" spring. People use common 52" and 56" for their front axle swaps all the time. Search I'm sure there are over 1000 posts on here about this setup.


will my stock steering box and pitment arm work?

Box should but you will probubly have to change the arm. All depends on what you want to do. Again Search.


if i can get my hands on that dually rear end would that be good? its a 8 lug floater, then i can take the spacers off right?


I have never seen a set of factory spacers on a rear end for DRW.... Some are wider than a normal SRW and some are not, it all depends on what you are getting it out of. Break out your tape measure and start looking.

[foodstamp]

i just heard their was spacer, i dont know from experiance...

but i found a ford 44 front on a 2000 something f250, should i get the rear axle while im at it, or keep the 14 bolt idea?

I believe that would be a Dana 50 sir. That is not a highly desireable piece.

[axisT6]

Your truck is a 94' so it has the 4L60E trans (electronic 700R). Also, there never was a factory 6 lug D60 on a Ford. Dually Rear 14 bolts had a wider housing, no spacers.

The 6 lug option you want is the 6 lug 14 SF and D44/10BLT front as mentioned. You can also run a 6 lug 14 FF in the rear, but you will have to have the hubs machined (contact Donovan for this).

I would highly recommend doing a little more homework before diving in.

As stated, that would be a D50. In your application, it would work great if the price was right. Be sure and get the rear axle with it because it will have the bastard ford metric bolt pattern.
Your steering box will work fine, just need a a drop steering arm. Check out Sky Manufacturing for an affordable set of spring hangers and a decent price on a steering kit.
How much lift was u planning on running and what tires?

[cj8scrambld]

Doesn't Sky Manufacturing only offer huge ass lift brackets....something like 8" above any spring lift? They should offer a lower lift option, they have a decent pre-made bracket for a good price. For another idea (one I liked) search a few pages back for "livin low suburbon"......or something like that. A nice clean low OEM look....although the OP never returned with any good photos of his brackets....makes me wonder if it was just a pic he snapped....? hint hint

Yeah the Sky brackets are 6", but by the sound of things that is probably the direction the build will go.

[foodstamp]

im prety sure its a 700r4, is their a way that i can make sure though?

im going for about 6 to 8 inches of lift, and 35's maybe 38's...

last night i made some drop hangers, well one anyways, ill have to get some pics up as soon as i find a camera.

i got word today that were going to cut off a dump bed on some guys 1 ton chevy, and then the truck is going to the smasher, so im going to try and take the rear end off that

i just re read the post about the metric bolt pattern..... how about a dodge front? will i be able to run the same pattern


am i going about this wrong, should i keep the ford or dodge idea or should i get a turbo 350 or 400 with a np205 and a chevy axle? i want it done right of corse, but i want it to be done cheap as possible, and be reliable

[cj8scrambld]

700R4 eneded in '93...it'll have a TV adjustment cable on it. The 4L60E (really a electronic 700R4) was intro'd in '94....no TV cable.

6 - 8" of lift..I guess you could use Sky's kit with a 0 - 2" lift GM spring setup.

Is that GM that's going to the smasher a 4x4? If so, grab the front axle. You could then use an early 90's NP241 Tcase for the D drop.

[Red Chevy]

Most likely the easiest way for u to tell the difference is to look on the passenger side of the tranny. 4L60E will have a big round plug for the wiring harness. My 93 model had a 4L60E. This is what is causing the issue with running a passenger drop front axle. Unless u can find a passenger drop 241 for your speed sensor, this tranny won't shift out of second. U could always put a manual shift kit in it. When I had my tranny rebuilt, it would hold any gear until the engine blew(literally), u just had to manual shift it.

Also, search for a thread of a guy puting a 205 behind an allison tranny. He was able to mount his speed sensor in the 205, something to look into.

[foodstamp]

yea its a 700r4... no round plug.... i have some funkey linkage going to it like a turbo 350 or 400...

i just took a 350/ tranny and t-case out of a 97 silverado, and that must be a 4l60e, it had a cable for linkage... right?

my t-case is a 241 C with 272 ratio

[cj8scrambld]

A '94, I am sure it is a 4L60E. Is that "funkey linkage" on it on the drivers side?<<<goes to your shifter.

So, now we're talking 38's........keep an eye out for a Ford D60....watch out for the metric lug pattern.....I forget the actual years......? 90/91 and up? With the Ford axle you can keep your Tcase.....you'll only have to deal with the axle install.....no Tcase swap etc...since you've just aquired a drivers drop drivetrain.

[b454rat]

I would go with a Ford axle, 44 or 60. This way you won't have to figure out what tranny/case to use, finding the right one etc. 77.5-79 Ford 3/4 and 1 tons is the axle your looking for. A dana 44 will probly do OK for what your gonna do, cheaper and easier to find than the 60 of the same year. Yard here has aboot 5-6 HP44s..

If you want a 60 but can't find one out of the 70s, Ferd started to use them again in 85 but in 1 tons only. They had the 36" spring pad width, which is about the only major difference. That style went to 92 I think, then they went to balljoints, then in the late 90s went with the metric crap. Try to stay away from the 93 and newer, it can work, but crossover is more expensive....

[foodstamp]

damn, ill need to look for some other truck then, this is a 200 something f250, and all the other trucks have the scisor style fronts... i looked under every ford their, and the 2000 was the only straight axle... time to hit up the junk yards

yes, the linkage goes straight off the tranny, to a butterfly setup on my frame rail, and up to the shifter on the steering collum

[Red Chevy]

If u can get the 2000 ford axles for a good price, grab it up.

[cj8scrambld]

yea its a 700r4... no round plug.... i have some funkey linkage going to it like a turbo 350 or 400...


Ok so the funky linkage is your shifter linkage, we have that out of the way. Now, were you "only" looking on the drivers side? Because what Red Chevy was talking about is located on the pass. side. Anyway, you "should" have a 4L60E in it.

[Red Chevy]

Ok, to clear any confusion about the tranny. Climb under and unplug the speed sensor on the tailhousing of the t-case. Get in your truck put it in drive and take off down the road. If it shifts through the with no problems it is a 700R4. If it takes off in first and shifts pretty hard into second and won't shift any further up or downshift then u will know it is a 4L60E.

[chevy_man]

I believe 91-92 was the last of the 700R4's. The 94 is definately a 4l60E unless somebody has swapped in an older 700.

[foodstamp]

im going to take it down the block in a sec. ill get back on that in a sec

[foodstamp]

you guys are right. i went to 4500 rpm and it wouldnt shift into 2nd...its a 4l60e... now whats the difference between the two? a 700r4 is a 3 speed with overdrive right? and i think mine is a 4 speed with overdrive, it grabs the last gear going 65

[abig84]

the 4l60 and 700r4 is basically the same thing, 3 speed with over drive (so technically a 4speed) except the 4l60 is computer controled

i got the same problem with my truck i swaped on a np208 and it wont shift but i only really use first. you can manually shift it. if you leave it first and get up to like 3000rpms and bump it up one itll shift into second
