So I got these after seeing on SPC site that they are recommended for both the GS and IS, pulled out my FUCA on my Jzs161 and guess what.....The ball joint is made in to the arm so no replacement here! I know for sure though that they do work in the front IS arms.

I've always read that the RUCA from the Gen1 IS are interchangeable with the GS and guys were swapping to these for the same reason. The balljoint could be replaced on the rear IS arm but not the rear GS arm. However I did not know this was the same for the front arms

So I guess my question now is, does the Front Upper control arms for the IS work on the GS hence allowing me to use the Adjustable SPC joint in the IS arms on my Aristo
