17/59 and 18/59

What's the difference between the 17/59 coils that came stock on my 13 jku sport and the 18/59 that come on the rubi?

What he said. Some did however come with two different springs on each side in front.

I had 13/56's in my jk. Upgraded to 19/60's. raised me 1 3/4" with aftermarket bumper and winch. And the ride is so much better! Don't know if you'd see that much of a difference.

If you swap out your 17's for a pair of 18"s you'll probably gain about 1/2". Depending on what options you got on your jeep is what spring rate you got. For instance Hard top, tow package, etc.
