Youxmoto Rear Window Lift Supports Gas Struts for Chevy Trailblazer/GMC Envoy 2002–2009 — Pair, OE Fit & Direct Replacement

Youxmoto 4576 rear window gas struts replace worn lift supports on compatible Trailblazer, Envoy, Rainier, Bravada and Ascender models to restore smooth, reliable hatch opening and holding.

If the rear window or hatch on your SUV no longer stays open, feels heavy, or lowers unexpectedly, worn gas lift supports are a common cause. These Youxmoto replacement struts match OE fitment numbers and restore the original lift performance with a direct-fit design. Each kit includes two gas struts sized to the factory measurements so installation is straightforward and requires only basic hand tools.

Will these gas struts fit my vehicle?

Yes, these 4576 rear window gas struts are manufactured to match the original equipment dimensions for the listed vehicles. They replace common OE part numbers so they fit directly where the factory units mounted.

• Compatible models: Chevrolet Trailblazer (2002–2009), GMC Envoy (2002–2009)
• Also fits: Buick Rainier (2004–2007), Oldsmobile Bravada (2002–2004), Isuzu Ascender (2004–2007)

How easy is installation and what tools do I need?

Installation is designed to be quick and simple with no special tools required. In most cases you can swap the old struts for the new ones in minutes using only common hand tools and a helper to support the window while you work.

• Required tools: flathead screwdriver or small pry tool, and a wrench or socket set if clip bolts are used
• Procedure: support hatch, remove retaining clips, pull off old strut, snap new strut into place
• Approximate time: 10–30 minutes for both sides depending on access and experience

What are the dimensions and performance details?

These gas springs are specified to the factory extension and compression lengths so they provide the same leverage and holding force as the originals. That ensures the hatch opens smoothly and remains securely propped at full extension.

• Extended length: 21.60 inches
• Compressed length: 14.01 inches
• Supplied as a pair: 2 pieces for left and right rear window support

What should I check before ordering?

Confirm compatibility by comparing your vehicle year and existing strut part numbers to the listing. Visual inspection of mounting ends and length will prevent ordering the wrong unit.

• Check current strut for matching OE numbers or measure extended/compressed length
• Verify your vehicle model year is included in the compatibility list
• Contact Youxmoto if uncertain — customer support can help confirm fit

Who is this for: This replacement kit is ideal for owners and DIY mechanics who drive a compatible Chevy Trailblazer, GMC Envoy, Buick Rainier, Oldsmobile Bravada or Isuzu Ascender and need to replace sagging or failed rear window lift supports. It’s also a practical buy for repair shops and fleet managers who want a direct-fit, value replacement part that restores safe, predictable hatch operation without modifying the vehicle.
