Detailed Description

The Stabilus 4B-023549 gas strut is a direct-fit style lift support for select 1999-2002 Audi TT and Audi TT Quattro models without a rear spoiler. It is specified with plastic socket connections at both ends and a 520 N force rating, making it a practical replacement for worn or weak rear hatch support hardware. This part cross-references URO (e.g., 8N8827552) for the same application.

Use this lift support when the rear lid no longer stays open, drops too quickly, or feels heavy during operation. The part number 4B-023549 is also referenced across multiple aftermarket catalogs, including AMS Automotive 6637 and Focus Auto Parts 86637, which helps confirm application matching for Audi TT rear hatch service.

What It Is Used For

• Restoring rear hatch or liftgate hold-open function
• Replacing a weak or leaking gas strut
• Correcting slow, uneven, or uncontrolled hatch movement
• Reducing strain when opening the rear lid on Audi TT and Audi TT Quattro models
• Addressing worn support hardware on vehicles without a rear spoiler

Installation Notes and Tips

Verify the vehicle is a 1999-2002 Audi TT or Audi TT Quattro without a rear spoiler before ordering. Confirm the plastic socket attachment style and compare the compressed and extended lengths to the original support. Replace supports in a stable position so the rear lid is properly secured during service.
