When comparing please note there is a difference in the spelling of two of those other kits.
There is "Tough Country" and "Tuff Country" I don't think the Tough Country is available anymore. I have to check on those names but I think that is correct.
The Tough Country was out of Tennessee and showed an H3 with 37's on it running on a dealers test track. I think they ran into some sort of issue with those.
I'm sure others can help clear this up, meanwhile I will do some looking.
I know these don't show the components but for the sake of discussion and for those that have not seen these, at least on this forum and adds to the data we have.
Tuff Country on 37's. The angle of the photograph adds to a crazy distored larger look of the entire vehicle.
I had this saved that a guy was selling, I believe a Rancho but I do remember this was on 37's.
This is someone I wheeled with on a Tuff Country lift. Had some different size wheels and tires. I might can find out what.
I have posted this also but shows a Rancho on left me in the middle with torsions to 23 1/2 and Tuff Country on right.
Here is all three again where I pulled the foreground angle trick to look big but it shows examples of lift stance.
