Detailed Description
Stabilus 4B-106389 is a gas-charged lift support engineered to restore controlled opening and holding force for the rear hatch on compatible Audi Q5 and Audi SQ5 models. The 640 N force rating, 500 mm extended length, and 301 mm compressed length are key specifications for matching the original support geometry and lift effort. This part cross-references Tuff Support 612622 for the same application.
Fits 2009-2017 Audi Q5, N/A, exc. power liftgate. Fits 2014-2017 Audi SQ5, N/A, exc. power liftgate. The Stabilus 4B-106389 is a practical OE-style replacement when the original hatch support no longer holds the liftgate in position or opens with consistent resistance.
What It Helps Solve
- Rear hatch that drops instead of staying open
- Weak or inconsistent liftgate support
- Slow or uneven hatch opening
- Loss of holding force in cold weather
- Wear-related replacement for aging gas struts
Installation Notes and Tips
Verify the vehicle is equipped without a power liftgate before ordering. Match the compressed length, extended length, rod diameter, tube diameter, and socket-style end fittings to the original support before installation. Support the hatch securely during replacement and confirm smooth operation after both sides are serviced as needed.
