From what I understand the spacers make the ride stiffer. Without doing the math and just reading Gilder's calculations of the spring rates, travel length, etc. it sounded like he had it dialed in to get the higher ride from the springs. I am not looking for a softer ride as mine are pretty good, but I also do not want stiffer coils than I already have, so if the Armada springs provide the 2" lift, that would be the "right" spring for me. My truck may be heavier than his (not sure) and ideally maybe I don't even have to cut the spring in order to compensate for the extra weight. Honestly I have no clue and I am just trying to get my mind around it for now, I am sure there are more details to be uncovered, and this being my escape from reality, I am having fun with it
