A-Premium Rear Window & Liftgate Lift Supports Struts 4-Piece Set for GM SUVs — Direct-Fit, Dampened Motion

A-Premium rear window and liftgate lift supports are a four-piece replacement set of gas struts designed to restore reliable, controlled opening and closing for the rear window and tailgate on compatible Cadillac, Chevrolet, and GMC SUVs.

These replacement lift supports are engineered to match the fit and function of factory struts for older full-size GM SUVs, providing smooth, damped motion for rear windows and liftgates. The set includes left and right units for both the window and the tailgate so you get complete coverage in one shipment. Each strut is packaged in thick cardboard for protection during transit, and multiple reference numbers are provided so you can confirm compatibility with your vehicle.

Which vehicles will these lift supports fit?

These A-Premium lift supports were selected for specific Cadillac, Chevrolet, and GMC models from the late 1990s through the mid-2000s. Compatibility covers both two-door and four-door configurations depending on model year; always verify with your vehicle details before ordering.

How do these struts improve rear window and tailgate operation?

Worn or weak gas struts can cause sluggish opening, uneven support, or sudden drops. Replacing them with matched-fit A-Premium supports restores smooth lift and consistent hold so the rear window and liftgate operate safely and predictably.

• Restores controlled, damped movement for safer operation
• Balances load to prevent sagging or sudden closing
• Helps prevent additional stress on mounting hardware and seals

What comes in the box and what should I expect during installation?

The product ships as a set of four lift supports—two for the rear window and two for the liftgate—packaged to resist shock during shipping. Installation is typically straightforward with common hand tools; many owners can swap struts in under an hour, though a helper or support prop is recommended for safety when removing the old parts.

• Package includes 4 lift supports with protective cardboard packaging
• Replacement is direct-fit for listed models—no modification expected
• Basic tools required; support the hatch/window during replacement

How do I confirm I’m ordering the correct part for my vehicle?

Before purchase, enter your vehicle year, make, and model in the listing’s selector and review any special notes from the seller. Cross-reference the provided A-Premium reference numbers against your existing struts or VIN-based fitment guides to ensure compatibility.

• Use the vehicle selector at the top-left of the product page
• Compare existing part numbers to SG230035, SG230056, SG330025, 4185, 4557
