Im getting closer and closer to finishing my SAS on my truck, now that im down to suspension i need some new coils for the new radius arms. the coils have to be for an EB or 78-79 Full Size. But i am having trouble finding some good felxy coils. i was thinking about getting some 9" lift coils and making taller coil towers to keep ride hight the same, but i would be able to have more flex from the bigger coils, but a lot of people told me that the bigger coils would be more stiff. I saw that Wild Horses has some "rock crawler" springs but the biggest lift they have is 5.5", that might be enough, im just not sure. im going to call around to see who has the best coils for my truck, but i thought i would ask here first too see if I could get some quick answers.
Thanks!

I have the Superflex coils from JBG and they are great. I think they have a 4" and a 6" version.

dont want to sound stupid or anything... but what is JBG?

Jeff's Bronco Graveyard

I have the 5.5" rock crawler from WH's and they work great. I also have alot of crap done to mine to use the spring fully.

just did an sas on a BII and put in the james duff eb coils way flexy... would highly reccomend

heres my whole system for the SAS, im using the james duff stage 3 radius arms for an EB, getting the spring cups from bronco grave yard, and the axle wedges form james duff.

the only thing that im really worried about is that my truck is a full size, and if those springs will hold it up fine. and i also dont want to lose any lift, i guess i can always just lower the coil towers if those 5.5"ers (if thats what i chose to run with) dont bring it to the hight it is at right now. But like i said im going to call around also, i just would like some input from people that have used the material and could give me some insite... and i also get stage fright on the phone. haha

I didnt realize Jeff's Bronco Graveyard and Bronco Graveyard were the same thing... haha school is taking its tole on my poor mind.

rockcrln: what is done to yours to use the coils "fully"?

Coils are rated by weight of a vehicle so EB Coils will probably be really soft with your fullsize rig and will be loose handling. I would see what Duff has for their fullsize Bronco line

What do you plan on doing with this truck?

you can also call a few places that make coils & get custom ones for extra flex & made for your trucks weight so the "rate" is right & not too stiff. isnt there a place called national spring? i cant remember the name but i am sure someone will.

wow, thank you so much for bringing that up. i knew i had forgotten to ask something. any body know of places that can make coils? i know national makes leaves but what about coils?

You can start here.....

You could also try some of the EB shops and ask them who you could try to make a custom one or see if they have something rated for your motor and truck.

If you go the custom route you should weigh your truck to get an exact weight, if you are going through all that trouble you should be as accurate as possible.

Good luck

I run the 3.5" rock crawler coils from Wild Horses. They are really soft. Some people don't like them because of the softness, and that they are prone to sagging. Keep in mind that to get a ton of travel you'll probably have to do something with the radius arms like going to a wristed arm, extended, etc. I run a wristed arm, but would really like to go to the Duffs for all around use. You might also want to address such issues as shock mounting if you are going to get extreme with the travel so that you don't bend the hell out of them.

Well you really didnt tell the specs of your rig, but I would check out a racecar supply mag and get some 15" ~225lb coils and build the top mount at wherever you want your ride height to be, or even make them adjustable. You can get those coils for 40 to $45 in most mags.

I say the Wild horses 5.5's..............The flex awesome, and have road manners like a cadillac.......:D

the specs are: '87 F-150, its got a 302 but am upgrading to a 351, c6 tranny, 205. thats all that i think would matter for the front. im building the truck as a trail rig, just something that i will have confedince in to do anything any trail will have to offer, mud rocks whatever. ill probably end up having to get some made, but i guell ill just have to see when i call.

My specs are as follows~
5225lbs (351W, hanson bumpers 12K warn and the kitchen sink)
wristed housing
longer tube arms w/johney joints
19" of front shock travel
5.5" WH RC springs
and rear flex that matches the front real well.

wow. your rig weighs that much? my 79 has a 460 & tips the scale at pretty close to 5500 with my 280 pound ass in it. dont have a winch yet.

Wow that is pretty heavy. What are you shooting for with the new buggy?

full size f-150...just get the 4 or 6 inch coils from jeffs. I have them on my 78 and like them alot.

i think the three places im going to call for coils is wild horses, bc bronco, and bronco grave yard.

any of yall know anything on the stage three radius arms with heim joints for the EB, that is what i plan on running, but if yall think the wristed arms are better and there are some places with some good tech write ups on that mod, let me know.

5.5 wild horses fronts at both ends the day they were installed new. no break in yet.

Coil Spring Specialties
look it up on the web, I've been buying stuff from him for 20 years. Tell him what you got & how you want it and you'll get it. My EB coils came in at the exact height and were perfectly indexed.

I am running "rock crawler" springs I thought they came from JBG. They have a winch option which I picked because they are EB springs and I am running a 78 bronco. The 5.5s lifted me about 4" at the time I installed them. They work well, but I know some of my buddys wild horses and Duffs work as well or better on their ebs. Mine has home made extended arms with heims on the end and now has a tube body and probably has closer to 4.5 inches with the weight loss. It has a 400, C6, 1/2 of 208 and a 205, but I don't know what that weighs as I am not done adding things.

I am thinking about 3700lbs. It will be full tube chassis, fiberglass rear quarters, not much inside (heater,cb and tunes) and I will be running the fox air shocks.

I plan on weight savings in these places this is on the light side.
no bumpers (-500 to -600lbs)
9kfor the 12k winch (-50lbs)
glass skins for the full body (-100 to -300)
frame and cage to full tube ( close to even)
4 link and fox airs for coils, radius arms and leafs (- 100lbs)
air/power lumbar seats w/back seat for master craft rubicon seats (-75lbs)
12 rancho shocks for none!! (-60lbs)
and more odds and ends.

so, anyone know anything about those james duff arms, or any way to build some good arms?

i have the JD arms. they work awesome, but i wish i would have went with a wristed arm instead. both flex the same, and i could have done the wristed arm for about $25 vs. $550 or whatever for the JD's. oh well, you live and you learn. :p

what about making some wristed arms with those big hiem joints on the ends like are on the JD arms? would that work or would there be too much play with all the joints? and where could i find a tech write up on wristed arms?

ok, i have searched, read, and searched some more. but i still cant find any good tech write ups on how to wrist the arms. i found one on the wristed axle that bc makes, but nothing on arms. i found this site http://www.broncofix.com/board/viewtopic.php?t=1613&highlight= i liked the way his bracket looks, but i cant tell how he has his radius arm. just need to find some good sources that say HOW TO...

and one more thing, why do some people only wrist one side? i couldnt reall find an answer.
Thanks all.

Don't know why you can't find the tech info. Search Google with "wristed arm" and you'll get five or six good links right off the bat, I just checked.

Wristed arms aren't high tech. Look at a few pics and you'll be able to figure it out.

wlendmn did one, its in the tech section at wt4wheeling.com, but the site has been down for a few days for some reason

if both sides are wristed with no pin in either, then the axle housing wont have much of nothing to keep it from twisting....itd be the same as running one link from the middle of the housing to the frame on each side

good writeup at http://www.broncoii4x4.com/

several good pics
what we are doing on a ranger soon!!!

thanks a lot guys, im going to wrist my passenger arm, and put spherical joints at the ends. its all coming together now...

ill post some pics of the finished product when im done for shits and giggles.

should of search here :p
