The black bushings do have a small amount of graphite mixed in with the polyurethane which has the potential to help with squeaking. But really, the best way to prevent Prothane bushings from squeaking is to use the supplied pre-lube and grease them properly at install. Just be sure to grease them properly to avoid any squeaking.
