I've had ladder cars and 4 bar's come into the shop with unbelievable stagger in the holes, and amazingly some of them actually went straight , although they had ridiculous amounts of preload in the bars and springs.
By their very design most ladder bars actually twist the rear if you use the adjuster link for a preload adjustment , they are actually intended to ease pinion angle adjustment not preload.
Bottom line is that if you needed to have that much stagger in the bar to achieve proper preload, there is something drastically wrong with the way the ladder bar crossmember or shock mounts were installed.
One thing for sure ,there wont be much housing yaw rotation since everything will be in a bind.
