Since the Rubicon Springs are shorter than the Superlift by 2 inches when I have my suspension at full droop on one side the Rubicon springs become fully unseated at the top by about an inch. It was to the point that I could remove the spring without using compressors. I'm not too worried about losing the spring because it has the retainer at the bottom and the top has the bump stops. I just don't like the idea that the spring does not even touch at full droop where as the Superlift does touch and need to be compressed in order to remove them even at full droop. I did go back to the old springs in the front and drove it around a bit through dips and bumps and if felt okay. I would prefer to use all the same springs but not if its going to limit travel or risk loosing a spring while flexing. Sorry if I am not being clear. I don't know a lot about springs and am reading as much as I can. From everything I have seen it is best to have the longest uncompressed spring possible because it gives a softer ride and allows for more flex, hence why I was liking the old springs.
