Common Replacement Reasons
- Rear hatch or liftgate drops instead of staying open

- Uneven opening effort on the hatch or cargo lid
- Loss of holding force in cold weather or with age
- Need for a direct replacement gas spring on BMW 328i or 328d xDrive models
Installation Notes
Verify the compressed length, extended length, force rating, and socket style before installation. Compare the existing support to Stabilus 3B-205791 to confirm the 8 mm rod and 18 mm tube dimensions match the vehicle’s original hardware points. For best results, replace supports in matched condition when the opposite side shows similar wear, and support the liftgate securely before removing the old unit.
