hard to say. i never drove it with the 5-spring leaf packs; too much lift for me to get into the jeep. so, i pulled 2 leaves from each pack, then finished the other details from the frame replacement that i started 9 years ago. the springs were rubicon express yj 4.5" springs. take a look at the short video i linked a few posts above this one.
it absolutely rides better, with better articulation, than it did with the original cj-width springs that had been on it since i purchased the jeep in 1993.
i re-added a leaf to the front pack because the front had settled a bit after driving it and wheeling it over the last month (the first month i've had it on the road since 2013). just wanted to get it to sit at about the same level it sat with the old springs. i liked that height - enough to clear my 34s, but low enough that i can still get into the driver seat without any difficulty.
