I would like to pull 1 tons under my J4000

[Alleneoc]

my truck is a 73 J4000 and I searched for axle swaps but most were talking about newer trucks not post mount spring trucks. So my question is, is there a 1 ton that is just a bolt in front and rear.

Anything you swap into the post mount J-trucks will require welding on new spring pads, some steering mods, possible shock mount relo, and mods to brake system to deal with front discs. Nothing is bolt on.

The good news is that the wide front spring spacing makes it real easy to locate spring pads without diff casting interference.
