Were those NEW leaf springs? I think you had something wrong......like maybe the wrong spring. Of course....and you've already said this, but the shackles ain't a good idea. You'll get it sorted out I am sure.
Those were the new springs yes. Those are the ones I still have I guess its possible I got the wrong ones I was only 17 when i put those on I didnt know much. Still dont apparently lol. I didnt know the spring hangers (shackles) were supposed to be angled.
