I'd like to get my hands om some thicker torsion bars but I would need to get them in Sweden, I think. The shipping cost would probably kill me. Or my wife would ...
It might be the angle of the camera, but it looks like the torsion bar on the right is bent or something and maybe the other side as well!
Maybe post within the Swedish or even European Mopar community for some HD T Bars. I've upgraded the T Bars in my wagon to 340 bars but might upgrade to 1 inch or even bigger.
