Well looking for opinions and ideas here. Yesterday I installed the front eibach front adjustable struts and 2.75 coils along with the 3 inch zone rear kit. I set the fronts to the second notch which was supposed to have the front end sitting at 3.5 inches. Thus retaining some rake but slightly less then factory. Well I have everything installed and I am sitting ungodly tail high.
Measurements being
Lf 38 1/8 rf 38 3/8 lr 42 3/8 re 42 3/4
Full tank of gas so the back being off seems about right.
I dont have before measurements because I came off of spacers however running off of average numbers posted on here the rear sound correct at about 3 inches. The front that was suppose to sit at 3.5 is only sitting about 1.5 even thought just the coils were suppose to be 2.75 themselves then on the second notch as the kit states it is suppose to be 3.5
The ride is amazing all the way around but the stance is terrible and 1.5 will not do. Has anyone else had this problem on the install. Right now CV angles are perfect so I'm thinking about jumping up 2 or maybe getting ballsy and going up 3 notches so start to bring it closer to level. Each notch should raise it .75 but my faith is no longer in eibachs measurements. Attached is the installed pic and angles of the CVS currently.

It may be my eyes or the pic, but I see a ring below the seat on the passenger side, but not on the driver’s side...maybe just the clocking of the spring seat...

So my measurements are

Front- 23.75"
Rear- 25"

Both sides were within an 1/8" so I just rounded

Front is on 6112s set to 2.3" clip
Rear is on Bilstein +1 rear coils. So you definitely way under advertised height up front.

So the rears are spot on being 3 inches. I dont understand unless they are just way off on rates of lift with the springs. My question is and wondering what people thoughts are on going up 2 or 3 notches. Ideally 3 would get me the height I was expecting maybe a little over. By the look of the CV shafts I do have a little room to play.

Is the part number on the eibach coils correct for your truck?

Yup first thing I checked! That was my initial thought
E30-27-001-02-20 for the springs

So, that's a loaded question in a sense, I get you want the height but you need to make sure you don't run over extended. When you get a chance measure how much down travel you have. Just tire gap to fender at ride height and than again with front tires off the ground. You're gonna want to keep around 2.5" of droop travel to maintain a decent ride quality. I'm gonna assume at the height you're sitting you prob have 4" of down travel so ball park you could prob get another 1.5 of lift (2 c clip notches) and still have a nice ride.

Edit I posted a while back about the rebel on air suspension I wheeled with running about 4" loft with NO upgrades and he had no issues. Take that with a grain of salt but there's some fudge room, so it is possible. I personally wouldn't run it that high, but for what you want it's worth a shot. After seeing all these installs of the eibach stuff coming up way short compared to advertised height I wonder if this is why they have production issues, I'm sure it rides super nice tho!

@FF1899 im not sure of your intentions, are you trying to do a 4” lift without the lift kit? Eibach only gives a 1” lift in the rear and you jumped to 3” the only option is to be incredibly tail high. Without pre measurements it’s really hard to do the math.
You mentioned that you had a spacer lift on there, a lot of those spacers require the top hat to be rotated 180 degrees that may be an issue but from the pictures they do look good. I would not recommend going over the 3.5 setting the amount of preload on those springs would definitely break something. If anything put the spacers on top of the eibachs.
I’m still trying to figure out your thought process? Are you trying to get it to be level? Or are you retaining your factory rake?

From the picture it looks like you got the full 3.5” in the front. It’s definitely got a good gap between the tire and fender

I wanted to go basically 3inch all the way around to maintain rake not all but most. The goal was 3.5 in the front 3 inches in the back. When I had the 3 inch spacer on the stock struts and 2inch rear spacer in the back it was in my eyes needing more rake the. Being me to this. 3.5 in the front and 3 inch in the rear. And with the top hats I had to reuse the stock ones so they were orientated to the new spring and they are not side to side specific so shouldn't change height at all also only bolt in 1 way.

With mine I have rubber coil spring isolators top and bottom. That may be giving me the full 3.5 ?

I didnt recieved anything other then the springs and the struts with the sleeve and ring. I'm thinking this is going to be somewhat trial and error for a little while with this stuff. There is no way I have 4 inches of rake by lifting the back 3 inches and actually getting even close to proper lift in the front. I'm expecting somewhere between 1.5 to 2 inches of rake all said and done which is where I would have been if the numbers held true. It's just a matter I think at this point of what ring to put it on looking at my angles right now. According to their documentation each notch should give an additional. 75 inches of lift. If I'm around 1.5 on springs and notch 1 it should take 2 more rings to get to 3 inches which I know is safe on the CV angles. It comes down to a matter of ride quality at this point and how steep the angles sit weather I go to 3. I guess do I go for it and see what happens lower back some if I need to or do I go 2 know it will be ok and continue to wonder what would happen if I went up 3 hahaha

If I grab a jack and measuring tape and jack at the front cross member to the specific heights will that give me a rough idea of CV angles. Hmmmm

On the coil springs themselves the word eibach should be readable not upside down. Their orientation matters. I can see the drivers side in you pictures look correct. I’m really trying to think if there was anything else that I read.

This is boggling my mind the only thing I can think of at all is the springs are not as advertised. Just shorter close to stock that is why I will have to up the rings
