The leaf springs in my BJ73 are fairly flat. I have added about 150lb or so to the nose of my vehicle with the addition of a strong front winch bumper and brush guard. I now have about 1.5" between the front bump stop and leaf spring, and 2.5" between the rear bump stop and leaf spring......I am considering some OME 2" lift medium springs. I am also considering air bag suspension. By this I mean removing all leafs but one on each corner used for locating the axle and adding air bags at each corner(individually inflated). From a simplicity/durability standpoint I see new leafs as the best answer. From a ride quality/adjustability standpoint the air bags seem attractive..............................Any opinions/experience?
