I have noticed that some 1-ton 1st genners have taller wheel travel than others. Is there a replacement coil spring that is out because I would like to raise my old goat alittle. Also did some 1-tons come with rear overload bump leaf springs and some did not, because mine does not have the bumps on the frame for the overload spring. I am thinking about rearching the leaf springs because they are flat with just the truck weight, I am also going to install air bags on the rear.
