I am in the middle of making a decision between IronMan or SPC upper control arms and I would love some feedback from real world experience. I’m going with King 2.5 suspension and want as low a maintenance option as possible. I was told that the IronMan use a factory style ball joint and bushings. I would love any real word world experience that could add to what I’ve learned so far. I would especially love to learn more about their longevity of service life. Thanks so much for your time.
