Question for anybody with the Exotek hangers. Are the Exotek suspension bushings better than the Durango ones? I rebuilt my truck last month and had a lot of slop at the rear inner hinge pin, even with new pins & arms. It seems like the "balls" that the hinge pins fit into are the culprits. The Exotek ones look the same, but do they fit in the Exotek hangers better? After one race the slop is a lot worse.
