Fitment and Application Details

Compatible With 2003-2017 Lincoln Navigator models, this Stabilus 4B-299507 gas spring matches the listed vehicle application for N/A position use. It is a practical OE-style replacement when the original lift support no longer holds position or opens smoothly. This part cross-references Dayco 86106 for the same application.

Common Problems This Part Can Address

  • Hatch, liftgate, or hood that drops instead of staying open
  • Weak or inconsistent opening force
  • Slow, uneven, or noisy lift support movement
  • Original gas strut losing pressure over time
  • Difficulty holding the rear opening in a raised position

Installation Notes and Tips

Verify the compressed length, extended length, force rating, and socket-style end connections before installation. Compare the original support to Stabilus 4B-299507 to confirm rod diameter, tube diameter, and attachment style match the vehicle. Inspect mounting points and retaining clips for wear before installing the new gas strut.

Quality Assurance

Stabilus is a recognized OE supplier for gas springs and lift supports. The 4B-299507 is built to the listed dimensional and force specifications for the 2003-2017 Lincoln Navigator application.
