Schludwiller and I installed his SLR lift springs this weekend and got about 6 inches of lift. Took us a minute to realize what was going on, but then realized that the shackles had gone up the wrong way when we lowered it. We were able to lift the truck back up and then it went back the right way afterwards. Sure looked funny at first though, especially since we hadn't don the other side yet! This picture shows how it was sitting. There is no jack or anything under the truck.
