Detailed Description

This part cross-references Monroe Shocks & Struts 172286 and 182286 for the same application.

Common Replacement Reasons

• Rear hatch, liftgate, or access panel no longer stays open
• Opening effort has increased due to weak gas pressure
• Lift support drops too quickly when raised
• Original strut shows wear, leakage, or reduced holding force
• Uneven or inconsistent support on the specified GM/Isuzu application

Installation Notes and Tips

Verify the existing strut length, end fittings, and mounting orientation before installation. Match the plastic socket connections and confirm the left-side application where required, especially on the 2003-2006 Isuzu Ascender. Compare the compressed and extended lengths to the original part to ensure proper travel and alignment. Replace only with the correct application-specific support for the vehicle listed.

Quality Assurance

Stabilus is a recognized OE supplier of gas springs and lift supports, and this part is built to the stated dimensions and force rating for the listed applications. Confirm fitment against the vehicle year, model, and position before ordering.
