Budget boost using zj coils - pass. side 1" lower than driver side?

OK, so i may be an idiot, but can't figure this out.
Installed zj coils + spacers yesterday, after the install the passenger side was exactly 1 inch lower than the driver side. Spacer was same measurement. The only thing I can think of is that the coils have different spring rates and I can try to reverse them? Has anyone else seen this happen? Any suggestions?

Thanks in advance for the help.

Maybe somebody really fat rode on that side in the donor vehicle.

some vehs have a longer or stiffer spring on the pass side because it's in the gutter more often

Do you have the factory coil isolator in on one side and not the other?

Factory coils do have a left and a right!

Ahah! Indirectly, I've found the answer to my own question.
The coils do have a left and right side - one is about 1/2" shorter.
Longer spring goes passenger side.
