Numbers on these rubicon springs are:
The numbers that matter are the last numbers. Are the numbers you posted the springs you're buying? Or the ones you have now?
What you have is a 14/56 combo whereas the max strength springs are 19/60. 14/56 is not likely to be worth the swap. Yours might already be stronger.
On my 2012 with Max tow I had 15/59. So the rear were close to the max strength, front not so much.
Do a google search for jeep jk springs. There's lots of posts on different forums that explain the spring rates in great detail.
