This is old news. Those springs are sitting on the shop floor now.
I was simply showing that I had read the long leaf spring tech post and was applying it to a real world situation that we both experienced in person. I learned a few things so thanks.
In your communication with Sky it was brought out that there's a balance needed between front and rear springs as well. My old 85 truck had almost no suspension travel in the rear springs when I ran the Superlift 4.5" springs. It was stable and climbed well in Moab, but when the suspension travel in the front was maxed out body roll was the next step and if the rear axle was the one on the off camber spot it was all body roll. Things were improved when I went to an Alcan setup in the rear (even with a small block) because they actually had some travel in them. My 4Runner is really pretty close to 50/50 which is much better.
It'll be interesting to see how your 4Runner performs with the Sky front and 63s in the rear vs. what you had before. This might be a good reason to explore the new rear spring from Sky as it could be a much better match for the front springs.
