The drag link looks pretty level but it does go downhill to the steering knuckle maby an inch but I'm sure the new springs/bushings will settle down some. Before the new springs I think it went uphill a bit, they were really dead.I'm going to take it to the frame/axle alignment shop this week and go from there. If there is a caster problem I'll redo the shackles to the stock length which I would have done if I knew they were longer before I put it back togeather.

 

Your shackles may be stock for some applications. My dually carcass I purchased for a donor has shackles the same length as yours. This truck came with a 6 in block in the back and a monster rear spring pack. I assumed the longer shackle was for leveling purposes because of all the meat stacked up in the rear, even though it would only make about 1/2' difference in ride height.

 

That's good to know, DNR also said there would not be much of a difference. Being longer would make the caster more positive and from what I've read getting close to no caster or negative caster is more apt to cause the Death Wobble. At least I should have a good itght front end when I'm all done.
