1 ton leaf spring help

[mrhino]

I went to my local "Power brake and spring" shop today to get some insight on what to do. according to the book, what i have is the top dog of springs. One guy called it a "wrecker package suspension" idk im just going by what he said. The other problem Iv run into, aside from a hard ride is the rear end is sagging. It sits lower than the front. Im assuming the extra weight of the liftgate all those years have taken there toll. My thought is If I replace these springs, Im going to have a rougher ride than I already do. Im going to try and place a spacer in there to bring the truck back to level and see how it goes. I still may need to replace the springs. when all is said and done.
