So, I called Rubicon Express today to get them to explain the difference in ride quality between the two different BB 2" list kits from Rubicon Express:
This Kit: http://www.rubiconexpress.com/Suspen...px?part=RE7030
Cheapest (about $230) comes with shocks designed for the 2" lift. Ride quality will be similar to stock just higher.
This Kit: RE7030RXJ - TJ/LJ 2" SPACER KIT W/MONOTUBE - Rubicon Express
Runs about $410. The are progressive shocks and represent an improvement in ride quality. Jeep should handle corners better, for example, but also handle bumps pretty well.
