EB Coils - think I found the unicorn

[littleredrangerhood]

I do not know the weight. I am hoping that the springs do squat a good bit. That is why I opted for the longest available length. If I have too, I can run a 1" spacer if I am still not happy with the amount of lift it gives.

Really, I don't care what lift these suckers give me as long as it is more than the 4.5" I already have. What I am really interested in is the extra flex I'll gain.

I do not know the weight.

Then you really have no idea what springs you'll need. Knowing the weight on the spring is the only way to determine the rate. You know the compressed height and the free length, the only other variable is the spring rate.

Yeah, I am kind of shooting from the hip on this one but I am confident I can make it work. I am also making some educated guesses based on the setup of my truck and the setup of some of the other guys running similar or even softer springs.

Those coils are going to sit WAY lower than 19" on that thing.

Do you know what the frontend (sprung weight) is on it?

Taking a guess that if it's around 2400lbs sprung, those coils are going to sink down to about 16.5" or so on that truck.

(there's another discussion about coils currently taking place here
Maybe some of the figures there might help you out as well.

For starters I doubt they are 250 Lb/in rate. Getting a 23.5" long coil into place with a stock RBV bucket is going to be a challenge. I believe Todd had to use a spring compressor to get his in. Bobby walter needs a compressor to get his Jeep coils inplace. I remember having a tough time getting the 19" SJ coils in place.

JBG superflex 6" coils for the 79 Bronco reported to only settle to 21" and they are 26" with a 200 Lb/in rate. That's on a Big Block truck too.

This guy needs to do more reading on the subject. But I guess it's too late now since he ordered the coils already. Pirate4x4 has lots of info on this subject.

FWIW Shawn I'm at around 2300 Lb's on the front of my B2. My 5.5" coils only settle 4.5". Total truck scaled in around 4500Lbs

I looked at getting the EB coils to fit in a stock bucket and it fits like ass. Most guys that do SAS with EB coils end up changing out the buckets to EB buckets anyway. You can space the coils from there if you need more height.

BTW if the coils don't work out for you I may take them off your hands for $160 Shipped

Good Luck

Stabbing in the dark................Good luck with that. Could get expensive, real fast. Next thing you know you'll be one of the TTB haters spouting SAS is the only way to go.

FWIW your not breaking new ground

Again good luck

Again, I am not stabbing in the dark. I researched this very thoroughly and you are wrong about Pirate4x4. There is not a lot of USEFUL info on that board concerning the EB coils in a TTB. I have put countless hours into finding a coil that is as close as possible to the ideal one for my application. As far as I know, I am the first person to actually get the spring rate info on the EB coils from BC Broncos. The owner told me that he just had it calculated himself not very long ago.

As far as your spring's compression versus how these springs will compress, you are mixing apples and oranges here. The BC coils are linear and your WH coils are progressive.

At this point, I cannot know for certain whether or not I will use the EB coil buckets. I am going to use a fail-proof strategy called 'trial and error'. Either they work with the stock buckets, or they don't. Simple as that.

BTW, I don't have any major problems with the TTB besides lack of flex, but the TTB can't be blamed for that. I will never become a "TTB hater", heck, I have put quite a bit of money into the thing because I don't want to give up on it. I like a challenge that way. However, I have been planning to do an SAS anyway in a couple years, moving up to 1 tons and 38.5" tires. In the meantime, I am still interested in trying to get the TTB to be the best it can be. Who knows, if this works maybe I won't do the SAS for another 5-10 years or something since the TTB definitely has nostalgic value for me.

All that being said, if these coils turn out not to work for me then I will strongly consider selling them to you for the $160 shipped. That seems fair enough to me.

I welded a piece of 1/8" strip (3/4" wide) to the coil bucket right at the top where the coil wants to protrude out a bit. This adds a bit more support to the coil and almost eliminated all the coil bow with the Jeep coils. The EB coils being the same dia, I think it'd work well with them too.

Getting a 23.5" long coil into place with a stock RBV bucket is going to be a challenge. I believe Todd had to use a spring compressor to get his in. Bobby walter needs a compressor to get his Jeep coils inplace. I remember having a tough time getting the 19" SJ coils in place.

Not if you have the proper lift on it (proper space between the axle and bucket).
If the coil is so long that you can't get it in easily, then it's not the right one for your suspension (if the axle can't drop down enough, you won't be using all of the coil's travel anyway).

FWIW, I'm just finishing up putting some 22" long coils into mine (SJ #JC60F). I raised the buckets up 2" and they easily dropped right in, with maybe an inch to spare. My axle brackets are 2.5", so this would effectively be the same as a 4.5" lift.

.

If you don't like what I said, fawk off.

So what the hell crawled up your ass?

Junkie could you get some pics of your recent work?

We all know johnny screws his new dodge, fawk him.

Nope, As Junkie said if I had to do that I wouldnt be using all the coil I have. With my rad arms the beam will drop farther then the coil will go. The coil is the limiting factor in the down travel not the beam binding.

I agree. This is a 21" long coil. The lower bucket has a 1.5" spacer under it.

The beam will drop further. The rotors were sitting on the ground.

Right now the front mounted shock is my limiter. Once I get the 14" travel one in place It should then become the spring. One day when I have the $$ and the right parts come along.....................

The front shocks were stopping any further movement. damn 12" stroke shocks.

Actually, the 5" exhaust isn't big enough for me to screw it.

 

[littleredrangerhood]

That would be like throwing a hot dog down a hallway.

That sounds like a personal problem.....

what make and model of spring is this?whats your compressed height from top of spring to bottom? thanks.

Nothing. However anytime anyone says anything against the TTB Suspension, they are labeled a "hater", and their opinions are argued over. I made several statements that MANY here would not agree with. I'm not going to argue my opinion with anyone. I've come to the realization that in many cases, but especially mine, TTB just is not the answer.
