I just upgraded to the Hotchkis rear swaybar and put new links on while I was at it. While trying to take the old links off, I learned they really weren't in bad shape at all, still pretty tight. So I just left them on the bar. The bar is in great shape, no bends or nicks or anything out of the ordinary.
It is off my short wheelbase, 2008 5.3 LT. I guess the 5.3's have a stiffer swaybar than the i6's? That would make sense because the swaybar I put on was supposed to make a huge improvement over stock, but it was more like a minor, subtle improvement.
