Detailed Description
The 5B-8539UB is a gas spring designed to match the fitment and operating dimensions used on Porsche 911 engine lid applications from 2005 through 2012. With a 330 N force rating, it provides the support needed for smooth lid movement while helping maintain controlled opening and closing behavior. The Stabilus 5B-8539UB is specified with plastic socket attachments at both ends, along with the listed compressed and extended lengths for proper fitment. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
What It Helps Address
- Weak or failing lid support
- Inconsistent opening effort
- Lid drop or poor hold-open performance
- Noise or rough movement from a worn gas spring
Installation Notes and Tips
Verify the compressed length, extended length, rod diameter, and socket-style connections before installation. Compare the original support to the 5B-8539UB to confirm the same mounting style and force rating. For Porsche 911 engine lid service, confirm the vehicle year and body configuration against the fitment list before ordering.
Quality Assurance
Stabilus is a recognized gas spring manufacturer, and this part is built to the listed specifications for application-specific replacement use.
