6.5" RockKrawler owners favor please?

I need a measurement please:
somebody with a Cherokee w/ 6.5" Rock Krawler coils up front -
No winch, no huge heavy bumper!
w/ a 4.0 engine.
HOW LONG ARE YOUR COILS TOP TO BOTTOM UNDER VEHICLE WEIGHT? (level ground obviously).
thanks in advance!

First measurement: 18" top to bottom
Thanks Rock Krawler!

Any more help??
the more the merrier.
