I have been researching parts that are included with a 4" suspension lift. I have discovered there isn't any bracket on the rear trac bar to adjust for the suspension lift.PO just left it stock. My jeep rides like your sitting on the axles. I have been in friends jeeps that are lifted and they have a little give. ( I know "its a jeep thing") but the shocks are fully compressed even when its on the lift. It rides like the suspension is frozen.
