What This Lift Support Helps Address

• Weak or failing lift support that no longer holds a panel in position
• Slow, uneven, or heavy opening action
• Loss of controlled movement in a lower hatch, glass, or access panel application
• Noise or instability caused by worn gas struts
• Replacement needs for BMW 535i GT and BMW 550i GT lower-position support points

Installation Notes and Tips

Verify the compressed length, extended length, rod diameter, and tube diameter before installation to confirm the correct match. The plastic socket ends should align with the original mounting points, and the support should be installed in the same orientation as the removed unit. Compare the old strut’s force rating and fitment position to ensure proper panel balance on BMW GT models.
