Thanks, Mike and SoK66. I'll step up to the RE5520. I'll also try to upgrade
to Rubicon Monotubes when I order the kit. I don't want to mix shackles, and
the RE5520 comes with new shackles.

Mike, taller lift springs are longer, measured along the arch.
In order to have more lift, and attach to the same mounts, the leaf is a
little longer....when compressed, (flattened) they will be longer, and
without the longer shackles, the spring will not be able to
compress/extend as much as it needs to be.....the spring will compress
to the point where the shackle is horizontal and the suspension will
feel like it's bottomed out.

Rumour was, a few years ago, that the 5520 (and all the other "Extreme"
kits from RE) uses National Spring (thumbs up) leafs, while the 5515
uses Pro Comp (thumbs down) leafs.
