Detailed Description

Stabilus 5B-203907 is a gas spring engineered to provide consistent support and controlled motion for the specified Chevrolet Impala application. The compact body dimensions, 8 mm rod diameter, and 18 mm tube diameter help match the original mounting and travel requirements, while the 325 N force rating supports predictable lift and hold performance. If you are replacing a worn lift support on a 2006, 2007, or 2008 Chevrolet Impala without spoiler, this part number 5B-203907 is the correct OE-style service option.

This part cross-references Dayco 84071 for the same application.

What It Helps Fix

  • Weak or failing lift support that no longer holds position
  • Hatch, trunk, or panel movement that drops too quickly
  • Uneven or inconsistent opening effort
  • Noise or binding caused by a worn gas spring
  • Loss of controlled support on the Chevrolet Impala rear opening

Installation Notes and Tips

Verify the vehicle is a 2006-2008 Chevrolet Impala without spoiler before ordering. Match the plastic socket attachment style and compare the compressed and extended lengths to the original support before installation. Replace the gas spring with the opening fully supported and confirm smooth operation after installation.

Stabilus is a recognized OE supplier of gas springs and lift supports, and this part is built to meet the dimensional and force requirements listed for the application.
