AiYiGu Rear Hatch Struts for Toyota Prius 2004–2009 — 2‑Piece 4094 OEM‑Fit Gas Lift Supports

AiYiGu 4094 rear hatch struts are a direct-fit pair designed to replace the worn lift supports on 2004–2009 Toyota Prius models, restoring smooth, secure opening and holding of the rear hatch.

Worn or failing hatch shocks can make lifting your Prius’ rear hatch hard, noisy, or unsafe. These two AiYiGu struts (left and right) match OEM dimensions and mounting style for an easy swap, returning reliable gas-assist performance without modifying the vehicle. The set replaces common part numbers associated with this application and arrives ready to install with no extra fasteners required.

How do these struts match my 2004–2009 Toyota Prius?

These lift supports are manufactured to fit Prius model years 2004, 2005, 2006, 2007, 2008, and 2009 that use the 4094-type rear hatch strut. They align with the factory bracket style and length specifications to provide the same motion range as original equipment.

• Direct compatibility with specified Prius years.
• OEM-replacement fit for 4094/PM2039/SG329018/SG329019.
• Compressed length 12.04" and extended length 19.74".
• Sold as a left-and-right pair for full hatch support.

What are the key installation steps and do I need special tools?

Installation requires no screws or special tools; the struts use pop-on ball-stud fittings. You should safely prop the hatch open with a rod or have a helper hold it while you remove the old struts and attach the new ones to avoid sudden closure.

• Support hatch before removing old struts.
• Use a flathead screwdriver to release the retaining clip if present.
• Pop new strut onto ball studs until it snaps into place.
• No additional fasteners included or typically required.

How will these replacement shocks affect hatch performance and safety?

Replacing fatigued struts restores proper counterbalance so the hatch opens smoothly and stays open at the intended angle. Fresh gas-assisted struts reduce sudden drops, minimize slamming, and make loading cargo easier and safer.

• Renewed lift force for controlled opening and closing.
• Reduces noise and jerky motion from worn supports.
• Helps prevent accidental hatch closures while loading.
• Two-piece set ensures even support across the hatch.

What warranty and part coverage come with the AiYiGu 4094 struts?

AiYiGu backs these hatch shocks with a two-year warranty against manufacturing defects. If you encounter fitment questions or product issues within that period, AiYiGu customer support can assist with replacement or troubleshooting.

• 24-month limited warranty from date of purchase.
• Covers defects in materials and workmanship.
• Customer support available for fitment or performance questions.

Who is this for: These AiYiGu 4094 rear hatch struts are intended for Toyota Prius owners (model years 2004–2009) whose rear lift supports are sagging, noisy, or no longer hold the hatch open. They suit DIYers who want an OEM-style replacement without custom adapters, fleet maintenance teams replacing aging components, and anyone seeking a straightforward, reliable upgrade covered by a two-year warranty.
