This Stabilus gas strut, part number 5B-434042, is an OE-style replacement built for BMW applications that need controlled lift and support. With a 280 N (63 lb) force rating, it helps maintain smooth opening and closing action for the supported panel or hatch.

Compatible with select BMW 228i, 228i xDrive, 230i, 230i xDrive, M2, M235i, M235i xDrive, M240i, and M240i xDrive models across the 2014-2022 range, this Stabilus 5B-434042 uses plastic socket connections at both ends for direct-fit service.

Product Details

The Stabilus 5B-434042 gas spring is specified for BMW vehicles that require a compact support strut with measured extension and controlled force output. Its 8 mm rod, 18 mm tube, and plastic socket ends are matched to the listed applications, making it a practical replacement for worn or weak lift support hardware. This part cross-references Tuff Support 613611 for the same application.

Common Issues It Can Help Address

  • Hatch, trunk, or panel that no longer stays open
  • Slow or uneven lift action
  • Drooping support due to gas pressure loss
  • Excessive effort needed to open or close the supported panel
  • Original strut wear from age and repeated cycling

Installation Notes

Verify the compressed length, extended length, force rating, and socket style before installation. Compare the existing strut to part number 5B-434042 and confirm the BMW model and year match the listed fitment. Replace only with the correct application-specific gas strut to maintain proper support and travel.

Quality Assurance

Stabilus is a recognized OE supplier for gas springs and lift supports, and this replacement is built to match the listed BMW applications with the specified dimensions and force rating.
