Howdy Cool Dudes and Dudettes,
I had some front end sag in my TJ and was thinking about going with some 2" or 3" springs to correct it. The initial problem is listed here:

Anyway, No one could give me a straight answer if Rubicon Springs were different from standard TJ springs. Since I acquired a set of Rubicon springs for free (though I'll buy my friend dinner next time I see him), I figured that I would give them a try. Here are the results:
The before photos:
Next is the TJ Spring next to the Rubicon spring (TJ on left). The height looks identical, however, I did discover a difference between the two. The TJ spring measured around .475 of an inch thick while the Rubicon spring measured about .507 of an inch thick. I am guessing that it has a stiffer spring rate, plus it is designed for a 4.0 while my TJ only has the 2.5.
The ending photos:
The conclusion:
Rubicon springs are different from a 2.5 litre TJ springs. Here is where my data is skewed: The Rubicon Springs I believe had less than 6 months of use. My TJ springs were 9 years old. Another factor that would be worth exploring is comparing the Rubicon springs to a 4.0 litre TJ to see if the engine size makes a difference with the springs initially installed on a TJ.
Sorry for the limited photos. Apparently we are restricted to 10 images.
Hope this answers some questions for someone in the future.
