I am going to comment here under the assumption the post gets moved:
Are you looking for shocks absorbers or new Lead Springs?
Jim Carter carries 1-Ton shock absorbers. I am not sure of the difference between the 1/2 and 1-ton shock absorbers, but he has both types.
Leaf springs are a different animal that I have yet to tackle. I know there are places that do custom work, probably worth looking for a local spring shop and talk to them about options.
