Does anyone know if I'll gain anything swapping out my stock jk sport unlimited springs for 2 door rubicon springs? Mine is an 11 and the springs are off a 12.

There is really no such thing as "Rubicon springs". What you want to look for is the last few digits in the part number label.

For example my OEM setup was 14 in the front 56 in the rear. I found a set of 18/59 from a 4 door and installed them in my 2 door. I ended up with about 1" extra lift and improved handling.

I just don't see how this will possibly give a boost in height but like the other guy said check the tags to see the spring rates, there's someone in our club that told another person that u WOULD gain height in this scenario but I just dont see how because of the significant weight difference. If u pull the trigger let us know your findings

The rubi springs have a different coil rate and I believe they are taller than a sahara or x's springs. You will gain about an inch of lift with swapping to rubi springs from non rubi springs. I know several people who have done so.

Thanks! I will update in a few days when I get the parts home and start this.

Not going to mess with it the springs were the same numbers

I just installed Rubi springs (18/55) and shocks from a fully loaded 4-door into my lowly 2-door X. Ride height at the center of the wheel, bottom of the top edge of the fender flare was 36" front, 36.5" rear. Afterward, same measurement point: 37.75" front, 37" rear.

Oh, and spring numbers from the X: 12/13 fronts, 25 rear. Yes, I said TWENTY-FIVE. Sort that one out.
