Terrible tragedy. Those 1,100lb rear rock crusher ACR springs can get you momentarily airborne on rough sections, expansion joints, *** holes and other bad roads. I have played w/ the dampening settings all across their full range. If you have the shocks set to full stiff you will get momentarily airborne. If set to the softer settings you can, and will, bounce all over the place, as the 1,100lb springs in the rear overpower the shocks themselves.
Why on God's green earth did Dodge put those rear spring rates on street ACR's I will never know. Unless your driving on smooth, prepared surfaces, those springs need to be changed out to 800lb units. This according to most, will put you back right in the middle of the rear shock adjustment range.
