i was told that you cant run a solid axel at 6"(4" coils +2"from axel)because of engine cross member.but broncograveyard has a kit so i imagine its possible.i would go higer(lke 10" but aint got the money for bigger tires and gears just yet.ok, im ready for the smartass comments now......

ok, you can, if you cut the front section of the crossmember, search for member chris85 xlt and i believe he has pics of how he did his on his superford page, its a good way to keep a low COG and still have the solid axle

wes

the axle doesnt give you 2"

i dont know where everyone is getting this 4" spring crap. run a 6" spring and be done with it, I know mine isnt any higher than a ttb truck with a 6". my diff comes close to the crossmember but dosent hit, I dont see a 4" coil even giving it enough clearance

i think thats just what i needed to hear.......so a 6" spring on a sa with 33's is gonna look the same as a 6" spring on ttb with 33's(i like more room in the wheel wells)?am i gonna need RA drop brackets for the sa or can i use my new ones?

you should really read thru what people have written here in this section about their swaps. Most of your qquestions will be answered there.

a 4" 78-79 lift spring with stock TTB spring buckets WILL give you 6" of lift when doing a sas

prove it tim. give some numbers here.
i know everyone says that the ttb buckets and old ones are different, but i have pictures to prove that is not true. there is about .5 inch difference between the two.
Are the older springs longer than the ttb ones? that is the only place that i could see gaining the two inches. it would not come from the lower mount ( which I know you are not implying) since either way the coils sits up a little off the axle tube depending on which type of front we are talking about.
the only way i could see using a 4" coil would be to lower the old buckets quite a bit o make up for the 2 inch shorter coil, but you would be lucky to use all (4 at least) of the mounting holes on the side of the bucket.
to specify my info, I ran old buckets, moved all the way up (Mine has the lower lip on it to go on the bottom of the frame), ran 8" 2wd fabtech ttb coils (.5" taller than superlift 6" ttb 4wd coils) and stock lower 79 mount on thop of the radius arm. I am like 1" taller than I was when I had a ttb front, and the difference came because these fabteck coils did not comporess as much as the ttb superlifts. that is the only difference i found with my sas

I am interested to see where you got an extra two inches.

well I have 6 inches of lift on my bronco and used 4" lift springs that davids78bronco provided for me and I am using the stock TTB coil buckets mount only 1" further forwad on the frame... what mor do you want me to prove!!! there it is plane as day i have it sitting in my driveway right now!

are you sure it is a 4" coil. what is the compressed length. IIRC, my free length was like 23.5, compressed it was 19 to 19.5 for the coils I am running now and with the 6" superlift. I wonder if the old coils for a 4" are really the same length as the 6" ttb coils. maybe that is where the difference is coming from.

just ran out with a flash light and a tape measure and the coil measure out to be about 19" hope this helps you out a little.

i've read on some forums that you gain 2" on the axle. guess the spring mounts are 2" higher then the ttb. i'm not sure on this just what i remember reading.
hope it helps

i think this is all coming from Fabitech. they said running a 6" coil would gain about 8" of lift. i could be wrong but i believe thats where i read it from.

The conversion utilizes the IFS type coil spring with a center mounting stud that yields 2" additional lift.
opps guess i misread it thought mounting stud was part of axle. f*&kin noobie:twak

massbronco, did you quote JBG or something? I think they are talking about using a ttb lower coils spring mount on top of the 78/9 rad arms (similar to chris c.), that would gain you an extra two inches. Chris85 can you verify that you gained approx that amount with your lower coil setup?

timmy, thanks. then my ASSumption seems to be about correct. i think the older coils are two inches longer for any given lift than the newer ttb. like I said with either the 6" superlift 4wd or the 8" fabtech 2wd coils, they are about 1 plus or minus at compressed height. So I would guess that a free 4" coil for 78/9 would be around 23 inches. Good to know.

i gained about 6-7" of lift with my 6" superlift TTB coils

i'm thinking of getting some Fabtech 6" 2wd coils hoping to lower the bronco an inch. think it would work?

About the crossmember. Yes, it will prob need trimming. If you use drop RA brackets, or extended arms, it will help alot. If the angle is still not that good, make a cut in the RA bracket and use a BFH to drop the face of the mounting plate back a couple degrees. Check for clearance. Adjust if necessary. Weld and gusset new 'custom' bracket.

my friend needed to trim his crossmember, and reangle his RA bracket. He did not use drop brackets. he also used 6" TTB coils on a 78 axle, giving him a total of about 8-9" of lift, mostly because of the coil buckets he made that were so tall.

the bronco graveyard kit is not at all like the do it yourself swaps the majority of people do. mostly because its just too damn expensive. secondly, it is rumored that the quality isnt that good, flex is poor, and it is more for show trucks than real wheelers.

there are also many good write ups on personnel pages, like Brian Soderblom's.

good luck, keep em comin.

It seems to me that one of the big variables and sources of confusion as far as net lift has to do with two things. One is that everyone uses springs for different applications (78-79 4x4, TTB 4x4, and even TIB 4x2) and thus the spring length and lift achieved can vary widely. The second variable is the Upper coil mount that is used. I have seen both the 78-79 application used as well as the stock TTB uppers, and some people make their own. So in order to really clear the fog some type of benchmark needs to be established i suppose. Perhaps there is some dimension somewhere that could be used or something.
I am planning my SAS right now. I have my D44, plan on using the 78-79 Radius arms, stock upper shock mount and coil bucket from TTB, TTB radius arm brackets (maybe 78-79 stock), 4 or 7 degree c bushings, and an adjustable track bar from superlift. Items that I am still finalizing are the steering (tie rods or heims?), coils, and the upper track bar mount.
The truck will be used for mild wheeling only as it is my daily driver, and the SAS is almost as much a repair as it is an upgrade. I am trying to be as frugal as possible, as I am on a college student budget as well.
One other big item I have to deal with is the engine crossmember. It is cracked severely and I am going to have to replace it. I am planning on using box steel, probably 2x6, and going from there when I pull the TTB. Has anyone done this or have the same problem?? If anyone has any input on this stuff, feel free to post up, PM, IM, email, whatever. And yes I know.....search. I have read through alot of posts, and while there are a lot of opinions, I am looking for direct evidence etc.

PS - all of this is on my F-150, but I can not find a very good forum or anything for trucks like I can broncs....hope yall can accept my ford cousin lol

FYI, skyjacker coils for ford ranger aplication measure 21" unsprung and 19" loaded under a 1990 302 bronco

massbronco, did you quote JBG or something
yes i did

wow, that is a hell of a spring rate for a ranger then. 2" sag under a fullsize pig seems to be quite litle for any bronco specific (ttb) coil. I guess that is what you were running? IIRC you seemed to like them right?

To the noob, one thing to consider, which maynot really matter much to you, is that with the old upper buckets, you can run a 9012 shock and get more travel than if you were to keep th ttb upper buckets. That is why most of us swapped them out.

Yeah I have knew that - but at this point right now, it would be more money, and also since i am not hard core wheelin i dont need the travel. It is something i could come back and do real easily for the same money, and also if i wanted to lower it some.....Thanks for the input....

I used 4" 78-79 Skyjacker coils on my 94F1504x4, keeping my stock TTB upper buckets. Used a 78 Bronco 44 with the stock 78 lower spring seats. I had a custom 18" track bar made at the local race-car shop and I mounted it to the middle of my crossmember. I have no clearance issues, and the truck still sits totally level after 2 years with the conversion. My previous 4" Rancho lift had the typical ass-high stance. A 6" spring or 4" spring will work, it all depends on your track-bar design. :imp

Yea, I couldn't believe it myself, but the tape doesn't lye! My bronco still isn't trail ready so I havn't got a chance to realy put them to the test yet. They did flex pretty good on our make shift ramp though. Heres the pichttp://www.superford.org/registry/vehicles/showmedia.php?id=88894
