Greasable Shackles

I'm looking for some stock replacement greasable shackles for my xj. I need a replacement shackle that adds NO lift. Any suggestions? Anything but Daystar please. And I'm not looking for a pair thats mostly what I've found, I only need one.

drill a hole into your stock shackles. screw in a zirc fitting. add opoly replacement bushings. its really that easy. shouldnt cost much more than bushings and zircs
