It's a common problem. I've got a bit of that on my L, too. There are traction bars made by Cal-Tracs and Rancho. Both are great and highly popular in the Lightning community. As for the new body style like yours I don't know much about them but if you go to
http://nloc.org and check out the GEN 2 Lightnings forum on the discussion board they might be able to help you out. You might also try the message board on
