This genuine ARB Drain Plug Assembly (0750201SP) is a precision-engineered replacement service part specifically designed for use with ARB high-strength differential covers. As a critical component for axle maintenance, this assembly features an integrated high-strength magnet that acts as a secondary filter for your gear oil.By capturing and holding fine metallic wear particles that naturally accumulate during gear operation, the magnetic plug prevents abrasive debris from circulating through your ring and pinion set or carrier bearings. This helps extend the service life of your drivetrain components and provides a visual indicator of internal wear during routine fluid changes.
