Stabilus 5B-5705XK Deck Lid Lift Support

Stabilus 5B-5705XK Gas Strut Overview

The Stabilus 5B-5705XK is a gas spring built for Audi rear lift support applications that require controlled opening and holding force. With a 650 N (146 lb) force rating, 297.5 mm extended length, and 202.5 mm compressed length, it matches the dimensions needed for specific Audi A4, A4 Quattro, A6, A6 Quattro, and S4 fitments.

This Stabilus 5B-5705XK uses plastic socket connections at both ends for a direct OE-style attachment layout. It is a fitment-specific replacement for rear hatch, trunk, or lift support service where the original strut has lost pressure or no longer holds position properly.

Detailed Description

Use the Stabilus 5B-5705XK when replacing a worn gas strut on select Audi models that use plastic socket end fittings and the listed length and force specifications. The part number 5B-5705XK is also referenced under OE-style interchange numbers including Audi 4B5 827 552 F and 4B5 827 552 G, along with Stabilus 5705XK and Lesjofors 8104234.

For Audi A4, A4 Quattro, A6, A6 Quattro, and S4 applications, correct length and force are critical for smooth lift support and secure closed-position retention. Matching the original mounting style and pressure rating helps restore consistent operation on the specified vehicle configurations.

Common Problems This Part Addresses

• Rear hatch or trunk lid that drops instead of staying open
• Weak lift support caused by loss of gas pressure
• Uneven or inconsistent opening effort
• Original strut that no longer matches OE length or end fittings
• Difficulty holding the rear lid in the raised position

Installation Notes and Tips

Verify the vehicle’s model year, body configuration, and spoiler status before ordering, since several Audi A4 applications are listed without rear spoiler and one 2003 A4 fitment is limited to chassis/VIN 8H-3-021 100. Compare the original strut’s compressed length, extended length, rod diameter, and socket-style ends to confirm match before installation.

Inspect the mounting points for wear or damage before transferring the new gas strut into service. Confirm that both plastic socket connections seat fully on the vehicle’s attachment points and that the lift support operates smoothly through the full travel range.

Quality Assurance

Stabilus is a recognized OE supplier for gas spring and lift support applications, and this part follows the dimensional and force specifications needed for the listed Audi fitments. The 5B-5705XK is built to match the application-specific requirements of the original support system.
