I bent one on my Kodiak Cub. They were not marked, but I think they were J2500 generic. They are 2500 pound rated.
I bought two 5000 pound rated and replaced both rear stabilizers. They come in different heights.
The bolt holes in the replacements I bought did not match perfectly. In fact the holes in the original stabilizer was butchered as well. I unbolted two more jacks. They were butchered as well and they were not all butchered the same.
I drilled one new hole for each new stabilizer jacks and enlarged one and used better bolts when remounting a front one. I also primed the bare steel in the new holes.
I prefer to use e-trailer as a source for parts. They have skilled people to help you get the correct stuff. I use email with them.

I wish you good luck and happy trails ahead!
