What It Helps Address

• Weak or failing lift support that no longer holds position
• Slow or uneven opening of the supported panel
• Drooping hood, hatch, or trunk movement on the listed Mercedes-Benz models
• Loss of controlled closing action caused by worn gas pressure
• Noise or instability from an aging support strut

Installation Notes and Tips

Verify the compressed length, extended length, force rating, and socket-style end fittings against the original support before installation. Confirm the vehicle application by model year and compare the OE reference numbers when ordering a replacement for a Mercedes-Benz E350 or E63 AMG. Inspect the mounting points for wear or damage before snapping the plastic socket ends into place.
