Kuah from SPL parts has confirmed that the rod ends that i currently have in stock for the multi-link are the same that SPL uses in their in-house products (TC rods, tie rods etc.)
the rod ends in the RUCA’s and other stuff that they import are not as good.
since i am upgrading to even better spec you can assume that they will be among the best rod ends in use in the industry for these parts.
but as mentioned, no one is using anything close to them.
sinc eyou cant get better, what does it matter?
SPL says theirs are Chromoly, zinc plated and since mine come from the same supplier and are a higher end rod end you can assume that they are atleast that.
i thought pictures would have sufficed and that you could have figured out the material from the pics.
Those Canadian ones have stronger threads too, with it being a fine thread, the root diameter is larger diameter, and therefore stronger.
I think that it is safe to assume that the grade of the threaded rod is far superior to the Chinese ones too (not to mention the tig welds over the mig).
you buy something cheap you often fu<k yourself, rather wait and invest your money in something better, or if you are forced to run something cheap, than be careful and take precatiuons in this case avoid corrosion and put liquid gasket onto the threads.
