I am really looking for a high quality smooth ride on a 4" lift. I would like front and rear springs. Although many lift kits get good reviews others can quickly come back to tell otherwise. The common best bang for the buck from what I understand is a BDS lift which seems to be quite pricy...anyone have a ball park figure for me so I can consider and maybe reconsider? Plans are for mudding, some climbing and alot of road use. I need to keep the fillings in my teeth around town and on the interstate...I'm looking for that cadillac ride.
