So just completed mid perch adjustment on shocks last night and getting aligned now. Gained about 1.25" at front. Watching RPG video looked quite easy, but on a truck with 26k miles and some of Michigan's finest salt, it took me a little over 2 hours to free the driver side to move up. A tip is to cut into the "Fox" sticker above, this also led to a binding condition that took some "Gentle persuasion" with a rubber mallet. What wa cut on the sticker is not exposed when complete. After lessons learned on driver side, passenger side took about 40 minutes. Did all with Manual tools and a free loaner from local car parts store.
For no cost, other than alignment, this a great improved look in my opinion. No feel of loss in comfort of drive as of yet.
