Cheaper and easier to just swap out the LCA's to 97-03, W-body store sells some nicely built ones with Moog Balljoints and Poly bushings. I also picked up the Dorman 25mm Front sway, the front end plants itself in corners nicely. I find the long Sway bar endlink setup with the 04+ is weak and that converting to the old 97-03 is a much stronger setup.

I'm dropped about 3" with about another 1/2-3/4" I could still go.
