Does this differential cover reuse the factory gasket?

No, this differential cover reuses the factory gasket. All other necessary mounting hardware is included with the cover.

How does the magnetic drain plug help?

The magnetic drain plug is designed to capture loose metal particles that may break off inside the differential. This helps protect your gears from abrasive wear.

What is the purpose of the calibration plug?

The calibration plug is set at a specific height to prevent overfilling the differential with gear oil. This takes the guesswork out of servicing your axle and ensures the correct oil level.
