Detailed Description
The Stabilus 5B-4043KY back glass lift support is specified for BMW rear glass applications where consistent lift assistance and secure hold-open performance are needed. With a 560 N force rating, metal blade rod connection, and metal socket tube connection, this lift support is built around the dimensions and attachment style required for the listed BMW 525i, 528i, and 540i fitments. If you are replacing a worn rear hatch glass strut on a BMW 525i, BMW 528i, or BMW 540i, this part number 5B-4043KY matches the application details needed for proper fitment.
This part cross-references AMS Automotive 6696 for the same application.
What It Helps Solve
- Rear glass that drops instead of staying open
- Weak or slow lift assist at the back glass
- Uneven or inconsistent opening effort
- Noise or binding from a worn lift support
- Loss of hold-open support on the rear glass
Installation Notes and Tips
Verify the compressed length, extended length, and end fittings before installation. Compare the existing support to part number 5B-4043KY to confirm the metal blade and metal socket attachment style. Support the rear glass during removal and replacement to prevent sudden movement. After installation, cycle the glass several times to confirm smooth operation and secure retention.
