Detailed Description

What It Helps Fix

• Weak hood or hatch support that no longer holds position
• Slow or uneven opening of a liftgate or rear glass
• Drooping hood, hatch, or window glass after release
• Loss of controlled lift due to worn gas pressure
• Binding or inconsistent movement from an aging support cylinder

Installation Notes and Tips

Verify the vehicle year, make, and model against the listed fitment before ordering. Compare the compressed length, extended length, stroke length, and end fittings to the original support to confirm the correct replacement. For best results, replace lift supports in pairs so the opening force remains balanced across the hood, hatch, or liftgate.

Before installation, support the hood, hatch, or glass securely and confirm the mounting points are clean and undamaged. After installation, cycle the panel slowly to check alignment and smooth operation on the Chevrolet Cavalier, Pontiac Sunbird, or other listed applications.
