A lot of modern-day muscle cars use hydraulic release bearing; they help simplify your drivetrain. The problem with the factory units comes with the inability to adjust them and the lack of travel. The RAM replacement bearing triples the throw length and also makes the release and engagement reaction quicker. The OEM replacements are a direct fitment for S197 and all LS applications, but RAM also offers a universal bearing depending on your transmission that can be adapted to a wide variety of applications.
