TadaMark Liftgate Struts for Chevy Suburban Tahoe Yukon Escalade — 2-Pack 4557, Gas-Charged Rear Hatch Support

If your Suburban, Tahoe, Yukon or Escalade hatch sags, drifts closed, or won’t stay open, these gas-charged lift supports replace weakened factory units to return consistent lift and secure hold. Engineered as exact replacements for reference numbers including 4557, SG230056, 8196034, 15734731 and 15766375, the pair arrives pre-tested and ready to install without special tools.

How do these struts restore a sagging liftgate?

The TadaMark shocks rebuild the spring force that deteriorates in older lift supports. By providing the correct extended and compressed lengths and matching mounting style, they balance the hatch and prevent sudden closures that can damage hinges or cause injury.

• Extended length: 24.69 inches; compressed length: 15.69 inches.
• Sold as a left-and-right pair to maintain even lift force.
• Gas-charged design replicates OEM feel and motion.
• Pre-tested for pressure and sealing to reduce early failure.

Will these fit my vehicle and replace OEM part numbers?

These lift supports are specified for rear hatch use on selected model years and mirror the fit and function of the original equipment. Confirm your vehicle’s model year and hatch design—especially Tahoe variants with rear defroster or without rear wiper qualifiers—before ordering.

• Compatible models: 2000–2004 Chevy Suburban 1500/2500, 1995–2004 Tahoe (except certain 2nd-design qualifiers), 1999–2004 GMC Yukon, 1999–2004 Cadillac Escalade.
• Reference numbers matched: 4557, SG230056, 8196034, 15734731, 15766375, SG230028.
• Designed for rear hatch left and right placement.
• No special adapters or tools required for direct swap.

How difficult is installation and what tools do I need?

Installation is straightforward for most DIYers and professional shops alike. The struts use common ball-and-socket mountings and fit directly where the original supports were attached, so you won’t normally need specialty tools or modifications.

• Typical tools: flat screwdriver or small pry tool to release retaining clips.
• Installation steps: support hatch, remove old strut clips, snap new struts onto ball studs, verify smooth operation.
• Includes two lift supports—one for each side—so both mounts are renewed at the same time.
• Follow vehicle-specific instructions for safe hatch support during replacement.

What durability and quality checks are included?

TadaMark tests each lift support before shipping to ensure proper internal pressure and sealing for reliable performance. The units are built to withstand regular opening cycles and to reduce stress on hinges and latches by completing the lift motion consistently.

• Factory pressure-tested for consistent lift force and leak resistance.
• Sturdy construction to resist corrosion and wear over time.
• Replaces worn shocks that can accelerate hinge and latch wear if left unattended.
• Packaged as a matched pair to maintain even hatch movement.

Who is this for: Owners and technicians caring for late-1990s to early-2000s General Motors SUVs—especially Suburban, Tahoe, Yukon and Escalade—who need a reliable, direct-replacement rear lift support set. Choose these TadaMark struts if you want OEM-length accuracy (24.69" extended / 15.69" compressed), matched pair balance, simple installation without special tools, and parts that correspond to common OEM reference numbers.
