EB Coils - think I found the unicorn

[Mutant Pony]

My 5.5 coils hit the frame way before the axle hits the bumpstop. Rather than spending big money on coils that are way to big, just move your buckets down a little. Make use of the wasted spring.
I have a sas on my MUD truck as well, I'm not gonna say anything bad about a TTB though. My offroad truck has a TTB and is a lot more fun to drive on the trails then my mud truck.

with all these springs getting thrown around its hard to keep track of whos got what.what springs do you all have installed right now-how much lift-how soft/streetable are they.if i could do a little thread jacking also what do you thinks needed for about 4" and closer to 300lb in than 200 lb in.i have double shocks with duff buckets(i'll cut them up if need be).i want more flex and street manners(at least where it don't scare me to drive on highway)

I had Rancho 3" XJ/ZJ springs on my BII.
They are rated at 240lbs
They gave about 2" lift initially (12.5" compressed), but sagged out over time (my BII is around 1500-1600lbs SPRUNG weight on the frontend).

I just the other day swapped to 6" Skyjacker XJ coils. These are sitting at about 5" lift on my BII (a bit over 16" compressed).
IIRC, they were claimed to be rated at 237lbs, but I think they may be a tad stiffer than the Rancho springs (maybe because the Ranchos had gotten all sacked out).

It seems like the SJ coils could work nicely for a 4" lift on a non-Supercab Ranger with a 4.0L, they seem like they'd support it.

I have those springs marked down as being 190 lb/in. Unless they changed the rating since the last time I checked, either they gave me the wrong number initially or you are talking with someone at JBG that is getting confused.

Part #23210 are 300lb/in but they are 27" long free length.

rickcdewitt:
I don't think there is really any spring out there that is going to give only 4" of lift with a rating of 300lb/in but here are some numbers for you to consider.

JBG #13202 320lb/in 18.5" free length
JBG #23202 320ln/in 18" free length
JBG #33510 progressive (unknown values) 21" free length

Tom's broncos SKU:6808 5.5" lift; 25" free, 19" compressed (under bronco)
these are progressive rate - 1st = 180, 2nd = 315

Maybe the 3.5" WH progressive coils would work for your needs. Personally, I like to stick with linear rate coils.

JBG (Deaver) did change the design on some of their springs probably about two years ago.
I have found a lot of published ratings to be questionable though. Putting the coil into a press or something with a scale under it might be the only reliable way to see what a specific spring has (short of knowing what the exact weight of a vehicle with "_______" springs on it is).

Yo,
yeah littleredrangerhood, your right, i had my part numbers off. This is the spring i was thinking of.
http://broncograveyard.com/bronco/i-23210_super_flex_coils_6_inch.htm It is a bit longer, but if i went with it, i was planning on using EB or 150 upper coil mount.

 

[littleredrangerhood]

Yeah, I thought that spring was just a little too long. I figured would rather come up short in height using EB buckets and then use a spacer than be too high even with the EB buckets.

Or the other way around.

The Old JBG 6" superflex (Deaver) 78-79 Bronco coils were 200 Lb/in rate and 26.25" free length.

Yes JBG did change the 6" lift coil this past spring. When I called about them they had none of the old ones in stock and were expecting the new ones that week.

The new 6" lift Superflex coils were bumped to 300 lb/in with a 24"free length.

i have stiff 4" duff 2wd b2 springs in my truck now with 3" duff axle brackets.almost anything will give it more flex its too bad the zj's diden't have a heavier v8 spring about 290-300#'s.my truck has a long wheelbase,wide stance,sway bars most of the time,and the double shocks so it should stay pretty stable with eb or f-150 stuff and raised buckets it sounds like.lets keep it up guys this is one of the best coil threads i've seen.

so is the pony the mud truck or trail truck?theres a guy around here who has a 4x4 67 GTO with the trunk lid and rear window removed to make room for a 4' wood bed in back. 455 makes a hell of a mud truck engine.kind of a shame though it used to be a nice goat

Or the other way around.

???? I said "Unless they changed the ratings of the springs since the last time I checked, . . . ". How can there be a "other way around". As far as the numbers you are reporting, why haven't they updated the site about them? I have those springs (#23209) as being 190 lb/in and 24.5" free length. Those numbers are from the Spring and they don't match any of your numbers. BTW, those springs are even more expensive than the BC broncos ones I ordered. You know, stabbing in the dark can get real expensive real quick

 

[rickcdewitt]

i wonder what the spring manufacturers would say about just choosing the rate you want and then cutting the spring to height on a band saw with water or oil cooling to save the temper?i don't know much about springs but it seems that might save everyone a lot of trouble if it was practical.

 

[littleredrangerhood]

It doesn't quite work that way. When you cut coils you change the rate. There is some equation in the tech library about it.

Nope you said

"either they gave me the wrong number initially or you are talking with someone at JBG that is getting confused."

I haven't ordered springs yet. Unlike some.


I guess I know nothing.

hmm i guess each loop has so much compression and the more loops the more travel=softer rate.it would be interesting to see what 8" or 10" XJ springs minus a few coils would behave like.so long as you were using a linear rate coil you could trim coils until its right.haha more guesswork

Dude, go back and read the F*cking post you quoted from. I prefaced that comment with the line, "Unless . . . ". The last time I edited that post was a couple minutes after I posted it yesterday so I haven't changed it. AND, the guy even admitted that he made a mistake and was talking about the wrong springs.

I don't know what you think you know or actually do know. However, I KNOW that I started this post trying to offer some useful information for other people that might be interested in using the BC bronco springs like I plan to. I am not looking for gratitude and I am certainly not looking for the approval of some wannabe know-it-all j@ck@ass like yourself. All you have done so far is say how sh*t is not going to work and I have know clue what I'm doing.

So, in light of that fact, let's try something here. Let's see if you can figure this out. What do Junkie, Todd, JohnnyU, and I all have in common? I admit that I am less knowledgable than some of the guys on the boards that have been running the TTB for the past >6 years but at the same time you're not talking to some stupid newbie here buddy, I know my way around a RBV.

 

[CopyKat]

Whatever Dude

I guess the fact that I've run EB coils for a year now means I don't know anything. Maybe my name says alot about me, maybe not. Clearly you don't know me. The three guys that you mentioned know me. If my first impression comes off as an Ass Hole then that's too bad.

My two suggestions still stand

1. Use the EB buckets off the bat.
2. 8" lift on a trail truck is "Stupid"

It's not your first impression that makes you seem like an @sshole, it's your consistent pessimistic, condescending posts that do. I might indeed take your suggestions in the long run but first I have to see what happens when I put the coils in. However, I know that I want at least 6-7.5" of lift because that is what I have now with the Susp and BL combined.
