Fitment and Application Details
This Stabilus lift support is listed for 2005-2007 Ford Five Hundred, 2005-2007 Ford Taurus, 2005-2007 Mercury Montego, and 2005 Mercury Sable. If you are searching for a 2005 Ford Taurus lift support, 2006 Ford Five Hundred gas strut, or 2007 Mercury Montego lift support, 5B-8031XK matches the confirmed vehicle coverage shown here.
The unit uses plastic socket connections at both ends and is specified with an 8 mm rod, 19 mm tube, and 288 mm extended length. Those dimensions matter when replacing a worn lift support because they determine the travel, mounting fit, and opening support characteristics for the vehicle panel.
Common Problems This Part Addresses
- Liftgate, trunk, or hood that drops instead of staying open
- Weak or inconsistent opening support
- Slow or uneven panel movement
- Original support that no longer holds pressure
- Noise or binding caused by a worn gas strut
Installation Notes
Verify the compressed length, extended length, and socket-style end fittings before installation. Compare the existing support to Stabilus 5B-8031XK to confirm the mounting style and force rating match the vehicle’s original specification. Replace supports in pairs when the opposite side shows similar wear, and support the panel securely during removal and installation.
