Variances with JBA 4"

No our fronts are almost the same height , maybe .5 inch d inference. But his rear springs are taller. It's possible he was accidentlyvsent the 6" rear springs. I've read post that stock height is 18.5-20" if you go on the high end (I assume with fresh factory springs at 20") then a true 4" would be whereas is. How ever if fsctoryvis 18"b then mine is about right.
Problem is I found some of my old measurements. And I managed to find a stock at the dealership sitting at 19.5 in the rear. So it's really hardv to tell where it should be with all the variances in stock.

I can't stop looking at the difference between you and TR911's front end. Your springs shouldn't be stacked like that at all. There is zero uptravel allowed with it like that. Is the lower spring the tender (softer) spring on that set up? How does it ride?

I guess it rides fine, but I have v the "CRD " springs and was told it would be better with the weight of the bumper. I thought that the v softer spring on top was due to the differences in spring rate through out the spring. That it was intentional.

What I meant was the difference in the springs on the front end and that your rigs look the same height. It would take A LOT of pressure to compress those springs so they are squeezed together like that.

New stock KK were at 18-18.50 right in that range in front

Maybe bad batch? Mine should be lighter than his.
Just found out the other guy installed his Dec 27, so 3wks ago. Would it settle 1.25 " to my level in a year?
Tom I'm talking about rear measurements. That's where I got the 19.5" stock . They ghost ave that front rake.

This was exactly my thoughts. Your springs should not be stacked like that. Do you have any other pics of you front springs. Specifically a view from the front like Texas'?

Any chance, and I'm just taking a shot in the dark that the pressure on those springs like that could be making the rear squat?

Just throwing out possibilities at this point. I don't see any reason a spring should be touching itself like that

I hope this ends well.

This was as close as I could get with out taking off my bumper.

I have no idea. I've been in contact with Marlin. I'll let y'all know what he says.

No , would maybe make it appear to squat but would n't

Pictures look normal to me , with the type of spring you will have that look

here is a picture of mine when first installed, never ran yet and before I fully adjusted them down. Mine look like yours now with the top two/three coils sitting there
The issue is too many are comparing these to OME springs which they are not. Two different ways of making springs.
One type of coil spring is the helical spring. Helical springs are helix-shaped wires used for compressive or tensile loads. They are easy to install, assemble, and they are available in different dimensions and diameters. Because of their accurate performance and constant spring rate, many car owners buy helical springs.

Another type of coil spring is the progressively-wound spring. This kind of coil spring is used for different road conditions or applications. It's called a progressively-wound spring because its coil pitch gets tighter as it reaches the top. Car owners upgrade their OE springs to progressively-wound springs for better traction, handling, and control.
The springs used in the JBA adjustable coilovers in the progressive rate

I may have to dig my old books out on suspension systems etc that I went to school for years ago. Seems like we need a course on springs and how they are made/ how they effect the ride etc

Well that makes me feel better, I would hate to have to replace the fronts. His aren't compressed as much, could he just have an older spring design?
The back is still a problem though, I'm thinking they were too soft. I have managed to split my stock bumpstop on the bottom bumpstop while wheeling, imt going to try and replace the rear bumpstops I got from JBA with hockey pucks. TexasRugby doesn't have extended bumpstops in the rear but he hasn't compressed his shocks as far as I have. My little rubber ring on the shock is all the way to the bottom and split. I'm thinking his rear springs must either be much stiffer or longer.

tommudd · **Posted:** Fri Jan 17, 2014 12:56 pm

Your problem with the rear bumpstops is you left them too long. You should of cut at least 3/4 to an inch off of the top.

JeepNCrowd · **Posted:** Fri Jan 17, 2014 12:58 pm

Wouldnt Longer ones have prevented my shock from reaching max compression better than a shorter one?

This picture the springs are stacked, in the middle.

I'm ready professor!

FWIW I have the OME setup, three conduit nut clevis left, top plates and 2 extra isos per side in the rear and sit at 21.5" drivers side and 22" passenger side. You would think the JBA 4" should put it around 22.5" - 23" right?

So I found this topic I posted almost a year ago. http://www.lostjeeps.com/forum/phpBB3/viewtopic.php?f=88&t=73845&p=772332#p772332
It give some peoples measurements as of a year ago. I just find it weird the the rear 4" springs on some people seem to be giving about the sane lift height ad the OME lift.
I feel like I'm being greedy, but if I got a defective pair or the wrong size then I'm hoping to get the right ones. I played a lot of money for every inch. If there is an explanation that accounts for the height differences then I'll be happy. I'm sure Marlin will sort this out.
perhaps in the mean time I can put my old daystar rear pucks in and boost it back up 24"?

No the spring is not stacked in that photo
Those are two springs one on top of one another
some early models were that way to achieve the height and correct weight

You're looking at this all wrong :banghead:

What most are running with the OME lift is the springs along with the extra upper isolators which in fact gives you at or almost 4 inches of lift
SO YES you are almost or at the same height BUT you don't have to stack up isolators etc to get that height
trust me I've ran every combo now on mine that there is almost and when I went to the 4 inch springs I gained only about 1/4 inch. BUT i did it with only the stock isolators
Really you need to step back and take a break
