post 38, measure from middle of wheel ,.....................................
so yes middle of the wheel, ( hub ) to bottom of the flare
reason for this is to remove tire size etc one person could have 2.5 inches of liftbut larger tires than the next guy , so it appears on paper to have bigger lift when it does not

If you look at before & after measurements in the pictures it works out to be 4" more in front and like 3" more in rear.

Another question - what's the best way to check the head light aiming and readjusting them, now that the truck is higher?

*****HELP*****
I just dropped off the Libby for an alignment at my local shop, and he said all he can do is set it to what the machine has for factory specs, unless I call the "lift company" (lol) to give him other specs to set it to.....
Do you know what other alignment specs to give him?
They're not working on it until tomorrow morning....

Camber and toe = OE spec

Caster anywhere from 2 degrees to 3.5 degrees and no more then 0.5 degrees cross caster.

It appears the mouse owes the mudd a steak dinner for the help. ;)

Seriously, I admire both of you. I always looked at vehicles as transportation and never had the desire, tools, or ability to take on projects like this. I can do basic maintenance and repairs, but that is my extent. Too afraid to fark something up. It is great to see people working together as well. Although my KJ will always be stock, I really have enjoyed this thread. Thank you.

your post is very interesting and informative.
I need to change the upper control arms and I would like to know your opinion after months of use.
do you recommend them?
Do you notice anything positive or negative about them compared to the Moog brand arms?

Regards
