Detailed Description

The Stabilus 5B-134323 gas spring is specified with an 8 mm rod, 18 mm tube, 319 mm extended length, and 203 mm compressed length. Its 290 N force rating is calibrated for the application, helping maintain smooth, controlled movement where a gas-charged support strut is required. This part cross-references Dorman - Conduct-Tite 86169 for the same application.

Fits 2005-2011 Cadillac STS, N/A. Use this Stabilus replacement when the original support strut no longer holds position, opens unevenly, or loses lift assistance. The 5B-134323 part number is also useful when matching an OE-style gas spring by length, force, and socket-style end fittings.

What It Is Used For

  • Restoring lift support when the original gas spring no longer stays extended
  • Correcting slow, weak, or uneven opening action
  • Replacing a worn support strut with matching dimensions and force
  • Addressing sagging panels or lids that no longer remain in position

Installation Notes and Tips

Verify the compressed length, extended length, rod diameter, tube diameter, and socket-style connections before installation. Compare the removed part to 5B-134323 to confirm the same mounting style and force rating. Install with the vehicle supported and the lift panel secured, then cycle the component to confirm smooth operation on the Cadillac STS.
