One has poly bushings, one has " dell-sphere pivot joints" . They both do the same thing but ones supposedly better than the other although I wouldn't spend the extra cash for the pivot joints. I had the one with poly and it worked great.Spohn shows two different panhard bars. Does anyone know why one is $40 more than the other? I'd like to replace my OEM panhard bar, but not sure which one to get.
Also, would just changing the rear lower control arms be beneficial...or is it better to change both rear upper and lower at the same time?
