ECCPP Liftgate and Rear Window Struts Kit — 2 Liftgate + 2 Window Supports for 2000–2004 GMC Yukon/Suburban, OEM-fit gas struts

If your tailgate or rear window no longer stays open, these replacement gas struts are engineered to match OEM fit and function for late‑model GMT800 SUVs. The kit includes two liftgate struts and two window glass supports built with high‑temperature insulation, multi‑lobe seals and factory‑level testing to give years of consistent lift performance without sagging or noisy operation.

How will these struts improve the feel and safety of my SUV liftgate?

Worn or weak struts can make the liftgate feel heavy and unpredictable. ECCPP gas springs supply controlled upward force so the liftgate opens smoothly and remains held open at its intended position, reducing the risk of the door falling shut unexpectedly.

• Restores consistent lift force and damping for smooth motion
• Secures the liftgate open to reduce accidental closures
• Reduces the effort needed to lift heavy tailgates

Do these parts fit my vehicle and match OEM specifications?

The set fits a wide range of GMT800 SUVs: GMC Yukon/Yukon XL 1999–2004, Chevrolet Suburban/Tahoe 2000–2004 and Cadillac Escalade 2000–2004. ECCPP designs these struts to meet or exceed OEM dimensions and performance, and they are compatible with reference parts 4557 and 4185.

• Compatibility list includes Yukon, Yukon XL, Suburban 1500/2500, Tahoe, Escalade
• Manufactured and tested to factory-style pressure and stroke specs
• Confirm vehicle year and part number before purchase

What materials and features extend these struts' lifespan?

These gas springs use high‑temperature piston rod insulation and multi‑lobe seals to resist heat, vibration and fluid loss. Built as 100% new components with quality control checks, they resist common failure modes like gas leakage and seal wear for longer service life.

• Insulated piston rods to limit heat transfer and wear
• Multi‑lobe sealing design improves resistance to vibration
• Tested units ensure consistent force and leak-free operation

How difficult is installation and what should I prepare?

Installation is straightforward and can be completed in minutes using basic hand tools. The struts mount with standard ball‑stud or clip fittings; no specialized tools or professional service are required in most cases.

• Simple swap: remove old strut and pop new unit onto ball studs
• Typical tools: small wrench or screwdriver for clips and fasteners
• Follow compatibility chart and safety precautions before starting
