The lift heights are in line with the advertised numbers from Eibach. When measuring as best as I could to the center of the hub I have +1 9/16 in the front and +1 1/8 in the rear.

My .02: Been driving on these 2 weeks now. Put the Eibach pro springs in the front. In the rear I went with their load-leveling system (250 lb/inch coils).
Overall, I think the ride is much improved from where it was right before the install. I think it’s damn close to being as good as a TRD Pro right off the lot when it comes to overall dampening. Even better than brand new when it comes to nose dive and body roll. I have a little added weight: hidden winch up front (~87lbs added), full drawer system in back and Gobi rack (~250 lbs). With this added weight, the truck was sitting pretty low with the relatively “soft” stock pro suspension. And the handling had significantly diminished, in terms of body roll/ nose dive, overall dampening “smoothness” and tracking stability at speed. These Eibach springs made my truck pleasant to drive again. They also obviously have the benefit of a small lift to accommodate slightly bigger tires and increased appendage size … whoops I meant aesthetic appeal!
I’m terms of install, I’ve always worked on my own cars but have zero experience dealing with this type of suspension … it was still only a half day job. The one and only hiccup I had was aligning the lower shock bolt after putting on the new springs up front. I would recommend:
- take a paint pen and mark the lower and upper perch before you change out springs to ensure they stay aligned. I threw the book at it (strap wrenches, round bar through the bolt hole, etc) to get it to rotate a little bit to fit and the top-hat would not turn for me. Ended up having to recompress the spring to turn the top hat just 1/4”. The cheapo spring compressors you rent from autozone didn’t work for me (gap inbetween the coils was too small), so this involved 2 separate trips to a local shop to use their wall-mounted spring compressor. Maybe spray some lube on the top-hat rubber bushing just in case you need to spin it ever so slightly? This could also just be my inexperience with coil-over shocks.
Also put on the Nitro-Gear UCAs as I wanted to get more caster to solve some darting tendencies at interstate speeds. I’ll post impressions of those in a different thread.
I wish I could give details on fitting 285/70/17’s with this setup, but I could not get the tires I wanted right now (Mickey Thompson Baja Boss (SL load)) as they are nationally backordered.

To those that have installed the '21 - '22 Eibach lift springs for Fox Suspension; did the Eibach springs level the truck or is there still noticeable rake?
I have a Wescott Designs lift kit on order but it seems the Eibach springs would be an easier install as they don't require swapping out the lower spring perches. Wescott offers a 2" iift in the front vs. Eibach's 1.4" lift in the front. They offer 1.25" iift in the back vs. Eibach's 1" in back.

Got the springs installed today and got it aligned. It aligned perfectly and so far I am very impressed with the springs and the ride is very comfortable.
Running 285/70/17 Toyo open country at3. No rubbing and didn’t even have to remove the mud flaps.

This might seem like a silly question but I am coming from the jeep world and am just starting to learn about Toyota. Can you combine the Eibach springs and the wescott Designs lift? I was initially going to go the WD route but I want to add a front bumper and winch and I feel the TRD Pro springs aren't going to cut it. I eventually will be adding a rear bumper as well.

Anyone?

I'm no expert...but will give my thoughts. There is a fixed length of space that the new spring and spacer must fit in....given that the new spring is taller and larger dia coil material...you may consider "coil binding" ...when the spring coils stack solid at or near full compression. I would call Westcott.
I would think you would need new UCAs at least. I am thinking that may be my next big project, since I cannot quite get the caster to spec (barely) and you would probably need more adjustment, possibly longer brake lines or abs cables, etc. definitely call Westcott. Also, stock tires (wife said not until the nittos wear out, she is the boss) before and after pics:
Before:
After (has been a bit of settle since the pic):

[MENTION=704548]LIMERUSH22[/MENTION] - We have developed our springs around the optimal damping zone that Fox has built into the shock. This was by way of shock dyno and ride evaluation. That said, we performed this on a bone stock vehicle with zero added weight. SO if you have lost height due to mods and would like to get the nose back up, then the combination would theoretically do so. The caveat being, it may put you out of the optimal damping zone and close to top-out which will adversely affect ride quality. That and the whole spring block thing...
[MENTION=647615]lewdog998[/MENTION] is correct in regards to spring block concerns. We design all of our applications so spring block is not possible, but moving the perch up would in fact reduce the amount of travel to block. Changing the spring location without changing the bump stop engagement can break other parts of the vehicle. As we have never tested this combination, we're unable to say with certainty that it would happen in this case. For reference, the total travel of this spring is approximately 211mm.
IMOPORTANT:
As our springs are designed around the factory perch and configuration, running them in tandem will void the million mile warranty on the springs.
Cliffs Notes: Lots of contingencies here, and not recommended by Eibach.

Idk that answer but I have the springs pre tsb update with a 1/4” top hat spacer and I added a full front bumper and it didn’t drop very much.

what about a .25" shim on top of the assembly, under the coilbucket that the shock bolts to? itll act as spacer to give you .5" lift, wont change the spring characteristcs, BUT itll make the overall assembly longer

I will say it sagged about 1/4 inch 8n the front after tossing all of my aluminum plates back on. If I am remembering correctly it is 22 from hub to fender in front and 23 in the back. I should probably measure all 4 again and write it down.
I am thinking about tires for when the time comes. I thought about going to 33s (255/80/17), but am now considering either sticking with stock size or maybe just moving up to 275/70 or 255/75.
Edit: Remeasured. Both fronts are at 22 even (no lean). Both rears are at 23 even. That is with the trd plate and a full set of rci aluminum skids.

Same concept as the Wescot kit, but at the top of the spring rather than at the perch. This is a much smaller amount of preload, so probability of premature blockulation would be less, but again my notes on the previous post still apply. Do at your own risk.

different concept...its lengthening the assembly. the westcott one just "compresses" the spring to change ride height but assembly remains same length. I know, "shaddup asz" lol

DOH! yeah I hastily read that.
Lengthening the assembly too far can cause premature stress and wear on factory ball joints and bushings. I don't know how close the fox dampers come to max droop so it's hard to say what this could potentially do to your setup.

I'm curious what top hat spacer you used? I'm looking to get a little bit more height out of the suspension without having to switch to a different shock at this time. No problems with the set up?

I used these toytec ones. They’re sold individually. I added them when I swapped the springs and everything is great. I also upgraded the UCA’s and have the duro bump stops. It rides amazing and have had zero problems.
