"Many of those people in the reviews are stating what height they got comparing to their worn out coils as well, rather than the height compared to stock height from the factory, as I have."
Only way to fly. Too many variables any other way.

I just wanted to add that I installed the V8 ZJ coils, from a wrecking yard on an XJ and measured and compared to the distance of 17" from flare to center of front hub. Those springs gave 1.5" of lift over the OEM distance on an XJ with 4.0 and Aw4

"So, in theory, it probably should be more like this:
Moog CC782 w/stock isolator = 3/4" - 1" lift (isolator is 1/4")
Moog CC782 w/o stock isolator + 3/4" spacer = 1.5" lift (spacer is actually 1")"
Hey Tbone I went to order those teraflex spacers and just noticed they're listed as being 1 1/4" thick where you have them at 1". Thought you might want to fix your post.

Anyways you happen to know where else they're sold? They're out of stock at Quadratec and I order my coils yesterday. Don't want to be hung up waiting.

Yeah, you're right. They do compress some after they're installed though, and mine measure about 1" now. I think the "moral of the story" at this point is, like you said, buy the parts, put them in, and tweak to get what you want! My numbers should probably just be used as a starting point.
I bought mine at Quadratec years ago (2013?) and they sat in my garage until this spring when I did the suspension upgrade. At that time, the idea was just to throw the spacers on with the OEM springs to help level out the Crowns. I'm sure glad I did the coils and longer shocks as well, though--it transformed the ride, handling and flex. I don't even know if they're available anymore, but I wonder if the Zone spacer is the same one--they both have that flat area on them that none of the others seem to have. Mine say "Teraflex" in some weird font on them on that flat area (as seen on Quadratec). It looked stupid to me, so I turned those to the inside.
EDIT: It looks like the same spacer is available directly from Teraflex: https://teraflex.com/shop_items/528f...d962f416e72e43

I registered and put them on my wish list so I reckon they'll e-mail me when/if ever they're in? I've got the site for the Zone ones saved but haven't really checked them out good. Plus I know how your suspension turned out so I'd like to get the same component so I stand a better chance of only having to do this once. Spacer # at Quadratec is 1905175. The one a Teraflex is 1905172. Both show the same specs though so I sent Teraflex an e-mail.
I'd thought about just adding the spacers to the original coils to but since they've got to be removed anyways I just ordered new ones.

Looks like I'm good to go.
Hi Earl,
Yes, it is the same part. That is a ¾” spacer that will fit on your XJ. It will give you 3/4” lift if used without the factory Isolator, and 1-1/4 lift if used with the factory isolator. I hope this helps you out.

So the new part # for the Teraflex spacer is 1905172. Google "teraflex 1905172" and there are a lot of vendors to choose from. Beings Teraflex answered my e-mail so fast I would have liked to bought off of them but shipping was $22+. Got the 2 spacers and 2 front bumpstops from Amazon for $5.80 shipping cost.

My experience with the MOOG 782s was different than many others say. After a few thousand miles I was at stock height or lower. This was paired with a new set of Bilstein shocks. As the coils sagged the progressive portion of the spring began to hit other coils making a clanking noise. Very annoying on my new suspension. This is on a Daily driver/trail rig/dune runner/ motorhome toad.
I have since replaced them with OME 2930 coils that instantly rode nicer and gave that lift back. 50K miles later and still a nice ride and at the original ride height after a very small amount of settling. Sadly about twice the cost.
In my opinion the MOOGs were not worth the effort.
I have seen many different methods of measuring the condition of the suspensions height. I have been using the factory manual specs for my old XJ.
This method uses the distance between the top of the axle tube and the bottom of the unibody. This is much more accurate than a fender flare measurement.
Front 6-3/4 to 7-3/4"
Rear 6 to 7"
It takes a little more work to do it this way but gives a more consistant measurement for me.

Sorry to hear that your experience didn't mirror mine.
After the settling in the first couple of hundred miles after fitting the coils, I've driven 6K miles on them and the height hasn't changed front or rear, and none of the lighter-rate coils are touching. I don't hear noise from them under any circumstances, even when fully compressing them off-road. The 6K miles has been a mix of daily driving, trail riding and towing a 2700# trailer with a weight-distributing hitch.
I am at 8.5" front and 7.5" rear, by your method, so that calculates out to:
Front lift: .75" to 1.75"
Rear lift: .5" to 1.5"
That's a pretty wide range, and not very useful to me for comparisons. If I take the median of those numbers, I get the following:
Front lift: 1.25" (0.5" lift from the coils without the spacer)
Rear lift: 1"
That is fairly close to what I get by measuring center of hub to bottom of flare, which for late-model XJs has been stated as 17.5" Fr. and 17" R. That measurement for me has been consistent and close enough for comparison. The additional benefit of this method is that I can more accurately take a measurement on the LF corner. With your method, the top of the axle can't easily be measured directly under the uniframe, due to the location of the differential. I've read through my FSM and, though "normal ride height" is referenced many times, I don't see where mine states what the standard is or how to measure it.
I did find the quote below in an old post here on the forums, however. According to this, standard stock suspension (which we always compare to) should be 6.25" - 7.25" front, 5.5" - 6.5" rear by the axle tube/uniframe measurement. However, we have to take into consideration that these measurements would not have been on a 4.0L-equipped XJ:
In conclusion, which is the best/most accurate method and standard for measurement? Your guess is as good as mine. The axle/uniframe measurement is likely best for comparing across models years, but I will stick to the hub/flare method for my personal comparisons.

Poking around in the back of the '85 Factory Service Manual the other day, I was surprised to find a section on suspensions that gives the factory's OFFICIAL measurements by the "dirty" method. For the benefit of anyone who is interested, here they are:
-------------------------------------------------------
Checking Front Ride Height
Measure front ride height with the vehicle unloaded (no luggage or passengers) and with the fuel tank full.
Place the vehicle on a level surface and measure the veryical distance between the top of the axle tube (A) and the underside of the frame sill (B). Refer to Figure 1 for driver's side measurement and Figure 2 for passenger side measurement. Be sure each measurement is taken from the top of the tube and not from the axle or shift motor housings.
With Standard or Soft Ride Suspension, vertical distance should be 17 cm (6-3/4 inches) plus or minus 13 mm (1/2 inch). With Heavy Duty Suspension, vertical distance should be 20 cm (7-3/4 inches) plus or minus 13 mm (1/2 inch).
Checking Rear Ride Height
Measure rear ride height with the vehicle unloaded (no luggage or passengers) and with the fuel tank full.
Place the vehicle on a level surface and measure the vertical distance between the top of the axle tube (C) and the underside of the frame sill (D) inboard of the jounce bumper (E).
With Standard or Soft Ride Suspension, vertical distance should be 15 cm (6 inches) plus or minus 13 mm (1/2 inch). With Heavy Duty Suspension, vertical distance should be 18 cm (7 inches) plus or minus 13 mm (1/2 inch).
