Anyone have an opinon on these? are there any alternative makers of rod ends out there? their the only brand I've been able to find in my part of the world, (except for no name agricultural ones) are these what you guys call heim joints?
I'm looking for a good quality product to do my 4 link suspension with.

If you look on my page you will see links to 3 different rod end Manufactureres (FK, QA1, etc) and at the bottom there is an excellent pdf on rod end tech.
