What lift are you running?
I am running the Rancho 2" sport lift for the Rubicon. Note it is a 3 1/2" lift on non Rubicon models. It has done great on the trails and rides like a passenger car on the street. I bought the one with the XL9000 series adjustable shocks. I soften them up on the street and stiffen them up for the Dunes and other types of off roading.
