well the higher the spring rate, the higher it will sit in the rear. they are all the same length, just a different spring rate.

I do not know honestly how much of a difference. but I read somewhere that a spring out of a rubicon hardtop (the 106) would lift a regular tj 1-2" but I could not find any other info on that being true.
