Stabilus 5B-255531 Gas Spring for Cobalt, G5, Pursuit
The Stabilus 5B-255531 gas spring is a direct-fit lift support built for specific Chevrolet and Pontiac applications. It uses plastic socket connections and OE-style dimensions to help restore controlled opening and closing action on the supported panel.

Detailed Description
This Stabilus gas spring is specified for 2005-2010 Chevrolet Cobalt, 2007-2010 Pontiac G5, and 2005-2006 Pontiac Pursuit. The 260 N force rating, compact compressed length, and matched socket-style ends make it a practical replacement when the original lift support no longer holds position or moves smoothly. The 5B-255531 part number is also cross-referenced by other aftermarket listings for the same application, including Monroe Shocks & Struts 172286 and 182286.
What It Helps Solve
- Hatch, trunk, or liftgate that drops instead of staying open
- Slow or uneven opening action
- Weak support caused by gas pressure loss
- Noise or binding from worn lift support hardware interfaces
- Restoration of controlled panel movement on supported applications
Installation Notes and Tips
Verify the rod and tube socket connections match the original support before installation. Compare the extended length, compressed length, and force rating to the removed unit to confirm application match. Install one side at a time when possible so the panel remains supported during service. For 2005-2010 Chevrolet Cobalt, 2007-2010 Pontiac G5, and 2005-2006 Pontiac Pursuit applications, confirm the mounting points and orientation before final fitment.
