I have the RE SOA springs on my Scrambler. I broke one last year on the Rubicon, and one this year at Slick Rock. Both times RE replaced them under warranty, even providing a matching pair so sit the same. My Jeep sees about 7 Rubicon level trips a year, nothing more extreme. Great they replace under warranty, but concerning they have broken twice - top leaf at the spring plate. Still run them, but considering carrying a spare top leaf.
