I just installed DJM's swaybars and in the front I used Energy Suspension's end links. It's best to actually get your rig lowered and if you're installing a swaybar, do that first as well, using your stock end links. Then you can check to see if you need longer or shorter ones to make your swaybar as close to parallel with the control arm as you can without interfering with anything like tie rods. Then on
www.energysuspension.com click on the "download catalog" (pdf) and on page 8 is their end link section. It explains how to measure and order the correct length and color. You don't need adjustable ones, just measure like the instructions show. You'd need to measure for the adjustable ones anyway. I had to grind a bit on the bushings because they didn't fit into the holes on my sway bar or control arm for some reason but it's easy with a Dremel or similar tool, could probably just use a razor knife too. I used the p/n and found the cheapest set on Ebay.
