How do these lift supports perform and what are their dimensions?

These gas struts deliver steady lift assistance and secure hold for the rear glass assembly, matching the original equipment’s stroke and force characteristics. Their extended and compressed lengths align with OE specifications so you get predictable motion and alignment after installation.

• Extended length: 21.60 inches.
• Compressed length: 14.01 inches.
• Sold as a pack of two—left and right supports included.

How difficult is installation and what tools do I need?

Installation is designed to be simple: the supports use common ball-stud fittings that snap on and off, letting most owners replace them without specialized equipment. Removing the old struts and installing the new pair typically requires basic hand tools and one person to support the window during the swap.

• No special tools required—common sockets or pliers usually suffice.
• One person can complete the job, though a helper is recommended for safety.
• Install by compressing the strut slightly, aligning ball sockets, and snapping onto the studs.

What should I expect for durability and maintenance?

These aftermarket gas struts are built to provide reliable performance under regular use, restoring the original ease of operation when the factory units fatigue. Proper installation and avoiding harsh impacts on the rear glass will extend their service life.

• Replace in pairs for even support and longer service life.
• Inspect mount studs and brackets for corrosion during installation.
• Wipe clean and check operation periodically to spot wear early.
