This is from the 2006 Nissan pathfinder service manual.
My wheel arch for my 4x4 SE with 265/70r16 should be 34.88" in the back. I am currently at 36.625" after armada springs and spacers. The spacers are supposed to lift it 1.75". 36.625-34.88=1.745 thus I'm sitting 1.745" above stock which is basically the spacer height. So the armada springs are essentially the same height as the stock springs, just stiffer. But definitely not too stiff.
Let me know if this doesn't make sense.
