A-Premium Rear Window & Liftgate Lift Supports for GM SUVs, Set of 4 - Direct Replacement Struts

A-Premium Rear Window and Liftgate Lift Supports are a direct-replacement strut kit that restores smooth, secure opening and holding of rear windows and liftgates on compatible GM SUVs.

If your Escalade, Suburban, Tahoe or Yukon rear glass or tailgate no longer stays open or lifts unevenly, these A-Premium replacement gas lift supports provide a straightforward, vehicle-specific fix. Sold as a set of four, the kit replaces both left and right supports for rear window and liftgate applications. Each strut is built to match factory fitment points and comes packaged to resist damage during shipping.

Which vehicles and years do these lift supports fit?

These supports were chosen to match common rear window and liftgate configurations on multiple GM full-size SUVs across model years. Always verify fit using your vehicle year, model, and door count before purchasing.

• Cadillac Escalade: Base 1999–2004, Escalade ESV 2003–2004, EXT 2001–2004 (4-door) — rear window & liftgate, both sides
• Chevrolet Suburban: 1500/2500 2000–2004 (4-door) and Suburban 1500/2500 2000–2003 (4-door) — rear window & liftgate, both sides
• Chevrolet Tahoe: 1995–2004 (2- and 4-door) and 2000–2003 (4-door) — rear window & liftgate, both sides
• GMC Yukon/Yukon XL: Yukon/Yukon Denali/Yukon XL 1500/2500 1999–2006 (4-door), Yukon/Yukon XL 1500/2500 1999–2004, Yukon Denali 2001–2004 (2-door) — rear window & liftgate, both sides

How do these struts install and what tools are required?

Installation is typically quick and uses common hand tools. The supports mount at the same ball-and-socket points as the originals and most installs can be completed without specialty equipment.

• Tools: flathead screwdriver or small pry tool and a ratchet/ wrench set if retaining bolts are used
• Process: support the window/tailgate, remove retaining clips or bolts, swap the old struts for the new ones, and reattach clips/bolts
• Time: most installations take 15–45 minutes per side depending on access

What’s included and how are the parts identified?

This kit ships with four complete lift supports and protective packaging. The set contains left and right units for both the rear window and the liftgate so you won’t need to order extra pieces separately.

• Package: 4 lift support struts with mounting ends, shipped in reinforced cardboard
• Reference numbers for matching: SG230035, SG230056, SG330025, 4185, 4557
• Recommendation: enter your vehicle information in the listing and read special notes before ordering to confirm fit

What performance and durability should I expect from A-Premium supports?

These gas-filled struts are engineered to provide consistent lift force and controlled closing compared with worn OEM units. They are made to withstand repeated opening cycles and environmental exposure typical for rear windows and liftgates.

• Function: restores reliable holding and smoother operation when opening or closing
• Durability: corrosion-resistant finishes and sealed gas chambers for longer service life
• Packaging: thick cardboard and shock-absorbing protection to prevent damage in transit

Who is this for: This replacement kit is aimed at owners and technicians of full-size GM SUVs — including Escalade, Suburban, Tahoe and Yukon families — who need a direct-fit, cost-effective repair for rear window or liftgate supports. It’s a practical choice for DIYers, body shop professionals, and fleet managers who want to restore safe, controlled operation without modifying the vehicle.
