Pitman arm is hitting tortion bar! Help?

Changing the ride height has nothing to do with the pitman arm hitting the torsion bar as they stay the same in relation to each other regardless of ride height. As for the pitman hitting the torsion bar, could be one of 2 things. Most likely the wrong pitman arm. Or it could be that its cheap chinese junk that the blind splines are machined wrong so its off and going to far to one side. I would go with the wrong arm. I had to go thru 3 before I found the correct one even though they were marked with the correct part number. Have you still got the old one to compare it to?
