Detailed Description

The Stabilus 5B-474939 is built for MultiPro tailgate auxiliary strut applications on Chevrolet Silverado and GMC Sierra trucks, including the Hummer EV Pickup. Its Lift-O-Mat dynamic damping design uses a controlled gas flow path to regulate extension speed, helping the tailgate move with less abruptness and a more precise stop. The result is a tailgate support engineered for smooth operation in the exact applications listed. This part number, 5B-474939, cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Tailgate drop that feels abrupt or uncontrolled.
• Uneven or inconsistent opening and closing motion.
• Loss of damping performance in the auxiliary strut.
• Need for a replacement tailgate support matched to the listed application.

Installation Notes and Tips

Verify the truck is equipped with the MultiPro tailgate auxiliary strut before ordering. Confirm the ball socket end style and compare the compressed and extended lengths to the original part. Mounting hardware is not listed as included, so reuse or replacement should be confirmed during installation. The part number 5B-474939 should be matched to the vehicle application and tailgate configuration before installation.
