What kind are they, If they're not Sway-a Ways they're probably F++ked up in the spline area. I have also heard of guys stripping the splines just putting them on. I would look at the splined are real close for imperfections, if thats not the case then I'd call whoever you got them from and make sure that you do not have to use them with some special torsion bar. I've got a set of the S-A-W adjustables sitting here but have yet to put them on. Mark Detro Englewood, FL
