B.ZSSY Rear Power Tailgate Lift Support Struts for 2015–2020 Suburban Tahoe Yukon XL — Pair, Direct OEM-Fit, Quiet Durable

B.ZSSY rear power tailgate lift support struts replace worn actuators to restore smooth, reliable automatic opening and closing for 2015–2020 Suburban, Tahoe and Yukon XL models.

If your vehicle’s power liftgate feels sluggish, noisy or won’t hold open, these direct-replacement lift support shock struts are designed to match factory fit and function. Engineered as a pair (left and right), they replace OE part numbers 84306929/84183515 and equivalents, restoring consistent motion and support for heavy rear liftgate doors. They are intended for standard factory motors—vehicles with aftermarket liftgate modifications may need a different solution.

How do these actuators compare to the original equipment?

Built from upgraded materials and finished with a protective coating, these actuators are designed to equal or exceed the original in durability and quiet operation.

What should I know before installation?

Installation is straightforward for anyone comfortable with basic automotive tasks, but the liftgate is heavy and must be secured during replacement. The product ships as a left-and-right pair and includes guidance to prevent pinched wiring or misalignment; if you’re doing the job solo, use a prop or have a helper on hand.

• Support tailgate with a sturdy prop or enlist a helper before removing old struts.
• Verify you have the standard factory motor—these are not for modified lift systems.
• Test open/close operation after installation to confirm smooth, quiet motion.

What performance and warranty coverage comes with these supports?

Expect consistent automatic opening and closing performance comparable to the original actuators, with quieter and smoother movement noted in quality-tested samples. B.ZSSY provides a 180-day guest support window in case of fitment or early failure issues; always follow safety guidance during mount and test procedures.
