eBay coil and strut spacers: part 1
You must be registered for see images attach
All jacked up, just kidding, only rear coil spacers are in and front is jacked up to show maximum droop.
My starting point of the stock suspension ground to fender heights are as follows:
Rear pass: 33.75"
Rear drive: 34.25"
Front pass: 31.25"
Front drive: 31.75" (no fender flare)
I am using the ground to fender height because it is the most practical and realistic values to real life application where as center hub to fender height is an irrelevant value. An example of this is my 2000 Suburban which has a factory center hub to fender height yet I have exactly the same approach angle, departure angle and break over angle as a stock 2017 2 door Wrangler Rubicon.
Enough of the soapbox, lets have some fun.

eBay 2.5" front and 2" rear spacer kit. Construction and materials look simple and solid only time will tell how they fare in the long run.

So I read a whole bunch of forum threads on how to install the spacers, most of which were done by someone else or a shop or a dealer. Watched a whole bunch of YouTube how to videos and they included extra steps that seemed completely unnecessary.

I tinkered for about 30 minutes with the rear passenger side spacer and figured out how to install the drivers side in about 10 minutes, and that includes taking the wheel off and putting it back on.

Step 2:
Remove OEM isolator
Clean coil perch
Place coil spacer on perch
Place OEM isolator on coil spacer
You do not have to unbolt the diff support bolt unless you do this for a living and like to charge your customers more in labor.

Step 3:
Rent coil compressor like these, most places rent them for free
Compress the coil at 12 o'clock and 4 o'clock, do not do 12 and 6, creates clearance issues
Bolt can be facing up or down, facing up is easier for me

Raise the axle and attache shock bolt
Raise the axle some more until coil is within 1" of the top perch
Release one of the coil compressors completely

Bam! And just like that you installed a 2" rear coil spacer under 10 minutes.
For those who like numbers that have little meaning:
Center hub to fender:
Rear driver 23.5"
Rear pass: 24"
Ground to fender:
Rear driver: 36"
Rear pass 35.75"
All these numbers will change once the strut spacers are in and once again after they are seated.
Stay tuned for more shenanigans!
