My 2dr sport came with 13/55. I switched the fronts to 15's and now it sits level even after adding ny LOD bumper.

There is not much of a length difference between a 14 and 19 spring, but the 19 is stiffer and will not sag as much under the Jeeps weight, hence the small lift. A 2,5" coil lift will give you more lift. Going from a 14 or 15 front to a 19 in the front and a 56 to a 59 or 60 at the back, will lift a 2 door maybe 1,5" max.

People that claim more, measure them right after the drop the Jeep back on it's wheels and forget that the coils will settle after a few miles on the road. Just look at pictures of people claiming 2" plus lift and a picture of a Jeep with a 2,5" lift and you will see there is a big difference.

The 19/60 will give you the full potential of factory height is all.
So are you guys saying your 2dr with 19/60 springs is as tall as 2.5" lift so you can run 35s no sweat....
If so, cool, then I suggest you add trackbar relocation bracket, extended swaybar links and either shock extensions or longer shocks to keep your geometry and handling.
I gained 2" in height. I didn't measure the coils side by side but the difference was at least 1 and .5 coils. There is only anecdotal evidence that they are "stiffer". The actual thickness of the coils themselves has been proven to be the same. Therefore the only other thing that could make a difference would be additional coils, which makes them taller.
