Before installing new end links, you might want to look at additional bracing of the mount points first. According to Mann Engineering, a stiffer sway bar will generally cause more flex in the mounting points of the ends links before the end links flex.

 

I have reinforcements for the rear on the way & I ordered a few sets of poly bushings to see what will fit the front & rear bar. I'll have King springs installed next week and figured it would be a good time to add some adjustable sway links. I'd like to keep the sway bars working properly.
