Now that I think of it...when mine bent, it was the rear half on the driver's side that bent...not the front section. Is that part of what rear spring mount sliders are designed to help with? I don't see how that sort of issue would be any different between CalTracs and Assassin bars, but I can see how bending the spring behind the front eye could result from CalTracs. I'm not sure about sliders helping w/ it or not? It definitely wouldn't be any different b/t the two styles of bars as far as bending the rear halves. Looking at the two designs, I don't really see how the Assassin bars would be any less prone to bending the front half of the spring? Maybe more so, IIRC you have to drill a hole in the leaf to mount the front pivot bracket with the Smiths stuff.  .
