Something’s bound up. The shackle should angle backward like in autoxcuda’s picture. Even with SS springs the shackle should angle back.
Just loosen everything up, jack it back up and set it back on the ground. If that doesn’t work you may need to try prying th shackles back with the load off the wheels. I had a set of shackles actually flip forward once after install, set the car really high in the air. I loosened everything up but in the end I had to pry them back so they set the correct way. No problems after that.
If that doesn’t work it’s possible there’s something wrong with the springs, you’ll have to call Hotchkis and see what they say. Usually the complaint with the Hotchkis leafs is that the car sits too low.
