The stock ball studs, like the stock threaded rod, are too hard, and break. The replacement stainless steel threaded rods will not break, can be bent over at 90 degree angle in a vise. I know, I did it. A stock threaded rod broke, did not bend far at all.
I don't know how hard the stainless steel ball studs from Winco are, but stainless steel, unless in the 440C range, cannot be hardened quite as hard as high carbon steels, so MAY be more ductile and not break as easily as the stock ones.
If I still had my LT I probably would have ordered some of the Winco ones by now and done a bench "vise" test on them.
If those did not break easily, it would be a really nice "fix", keeping the fittment basically stock, with the only change being material used.
The real issue is not the "strength" of the parts, but their "hardness", or "brittleness". The stainless steel has a considerably lower tensile strength (still WAY higher than needed), but much higher ductility.
A high strength part can often break way before a part with much lower tensile strength due to impact forces. That is one of the things one has to take into account when designing machine parts, how the part is loaded by expected forces.
In case you did not know, I am a design engineer myself, with a LONG
history of working with machine design and materials. About ready to semi-retire though.
The studs you have may very well be "softer", thus much less likely to break as the stock ones do, even though the same thread size.
