Understand the actual lift IS ONLY the coils. Every other part is installed at ride height or after the new coils are in. Dont try and install everything up on stands like some do.
After you get the new coils in drop the jeep back down to the ground w/ either tires on or stands under the axles.
Set track bars (center axles next) install the rear track bar and center the axles laterally.
Below was a short write up i did for another member on CA install.
Ok, you will have to decide on rear lower lengths ( or how far you want to move the axle back), ideally +.25 is perfect at 3.5". Mine is set back 1/2" and some go as much as 1" back. Just remember more than .5 is honestly unnecessary and can cause other interference problems.
Heres the gist of it basically you want to set the lowers matching in length. Then W/ the lower arms Mounted up, the uppers can be adjusted to match the mounts. Basically you set/hold pinion with jack and adjust the arms out to each mount, NO measuring required.
Front
1/ take each lower arm and center the joints up. Measure from eye to eye 23 1/4
2/ pair the arms together and feed 2 bolts through to match lengths (video)

3/ mount lowers leaving bolts loose
4/ position a jack under the pinion. You want to read + 2° using a angle on the flange (pinion angle)
5/ take the drivers side upper arm and install the frame side mount (or non adjustable side) 6/ rotate the joint out to match the opposite mount hole (both bolts should slide in/out with little effort)
7/ take the passenger side arm and do the same thing. (All 4 upper CA bolts should slide in/out without effort)
8/ drop jack and measure pinion again +1° or + 2° is acceptable (4° - 5° caster)
9/ tighten jam nuts TIGHT (you can remove one arm at a time to do so .. Make sure you don't mess with the setting.
10/tighten all bolts lowers 125 uppers 75 ft lbs
Rear
Rear setup is the same, lowers first, mount, then uppers matching the mounts. After lowers are set and installed the axle needs to be put on stands and tires removed to get to the upper arms.
1/ set lowers to 20" - 20 3/4 ( + 1/4 to 1" )
2/mount lowers leaving bolts loose
3/ axle on stands remove tires
4/ pinion angle. pinion in the rear is relative to DS angle. You want the pinion to be -2° lower then the driveshaft. 5/ use jack to hold -2°
6/ start with the drivers arm and match the mounts (like you did with the front)
7/ do the same with the passenger arm
8/ recheck the angle before tightening things up. All 4 arms 125 ft lbs
If you notice i gave no lengths for the uppers ... You dont need to set them .. Matching the mount locations removes any bind that may be present with same length uppers. With the lowers matching up the uppers do not meed to be the same lengths.
People often set Whatever the manufacturer recommends and has to deal with alignment issues because no 2 jeeps are alike.
I set my arm up following the above steps and my alignment was almost perfect. Plus messing with jam nuts is a pain in the ass. Do it right the first time and save yourself the
I see a lot of jacked up arm instals on here. More times then not its a shop that should know what they're doing. The owner complains of poor handling etc. one person ripped her upper mount off, prob due to setup and binding. Take your time, read this a few times and understand it. Once understood the process is not difficult.
Good luck
