TadaMark Liftgate Struts for Chevy Suburban Tahoe Yukon Escalade — 2-Pack 4557 Direct-Fit Rear Hatch Support, OE-Length

TadaMark rear liftgate struts (part 4557) are a direct-fit replacement for sagging hatch supports on select Chevy, GMC and Cadillac SUVs, restoring smooth, reliable rear hatch operation.

If the rear hatch on your Suburban, Tahoe, Yukon or Escalade won't stay open or feels heavy and slow, these two replacement lift supports provide the force and fitment you need to safely hold the liftgate. Engineered to match OE mounting points and lengths, they come as a pair and ship pre-tested so you can swap them in with basic tools in minutes. Exact reference numbers include 4557, SG230056, 8196034 and others listed for cross-reference.

How do these struts fit my vehicle?

These lift supports are made to fit rear hatch applications for specific model years and commonly use the same factory attachment points as the originals. Fitment covers 2000–2004 Chevy Suburban 1500 and 2500, 1995–2004 Tahoe (with noted qualifiers), 1999–2004 GMC Yukon and 1999–2004 Cadillac Escalade. Always confirm your OEM reference number or compare compressed/extended lengths before ordering.

What performance can I expect after replacement?

After installing these replacement shocks you should notice a firm, steady lift and reliable hold at full extension so the hatch stays open without sudden drops. The struts are tested prior to shipping for proper gas pressure and smooth stroke, helping reduce strain on hinges and linkage. While they restore normal operation, avoid making claims beyond mechanical fit and function.

• Smoother opening and closing with consistent damping
• Secure hold at full extension to prevent accidental closure
• Reduced wear on hinges and liftgate hardware over time
• Pre-shipment testing ensures working pressure and stroke

How hard is the installation and what tools do I need?

Installation is straightforward and requires no special tools—most jobs are completed with a basic socket or wrench and a small flat tool or pick to release retaining clips. The supports include standard ball-socket ends that snap onto factory studs; replace both sides as a pair to maintain balanced force. If your hatch has unique trim or a rear wiper assembly, remove any obstructing panels per the vehicle service guide.

• Typical tools: ratchet, appropriate socket, small flat screwdriver or trim pick
• Time estimate: 15–30 minutes for an average DIYer
• Tip: support the open hatch while removing the old strut
• Replace both left and right units together for even lift

What are the key dimensions and package contents?

Each strut is specified with a compressed length of 15.69 inches and an extended length of 24.69 inches, matching the original equipment stroke for these applications. The shipment includes two lift supports—one for the left side and one for the right—so you receive a complete rear hatch repair kit. Confirm these measurements against your vehicle's existing struts before purchasing.

• Compressed length: 15.69 inches
• Extended length: 24.69 inches
• Package includes: 2 rear hatch lift supports (left & right)
• Designed as an exact replacement for referenced OEM part numbers
