AiYiGu Rear Hatch Struts for 2004–2009 Toyota Prius — Direct-Fit Gas-Filled Pair Restores Smooth Opening

AiYiGu 4094 rear hatch struts are a direct-fit pair designed to restore smooth, controlled opening and support of the rear liftgate on 2004–2009 Toyota Prius models.

If your Prius hatch no longer holds open, slams shut, or moves unevenly, these replacement gas struts (2 pieces) are built to match the original lift support specifications and return reliable operation. They replace OEM part numbers such as 4094, PM2039, SG329018, SG329019, 68950-0W204, 68960-0W193 and 68960-0W194 and come in a ready-to-install pair for left and right sides. The design focuses on straightforward retrofit without special hardware, backed by a two-year warranty from AiYiGu.

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

The AiYiGu 4094 struts are manufactured to fit the second-generation Prius hatch geometry. They match the factory mounting points and stroke lengths so they reconnect to the original brackets without modifying the lift gate or body. Check the model years listed and the OEM cross-reference to confirm compatibility.

• Compatible years: 2004, 2005, 2006, 2007, 2008, 2009 Prius (rear hatch)
• Replaces OEM: 4094, PM2039, SG329018, SG329019, 68950-0W204, 68960-0W193, 68960-0W194

What are the physical dimensions and performance details?

Each strut has a compressed length of 12.04 inches and an extended length of 19.74 inches, matching the factory stroke to ensure proper hatch travel and hold. The gas-charged design provides consistent lift force over repeated cycles and restores the expected opening speed and staying power of the hatch without jerking or sagging.

• Extended length: 19.74 inches
• Gas-filled for steady lift and damping

How difficult is installation and what tools are needed?

Installation is straightforward and intended for a quick DIY swap. There are no screws or special fasteners included; the replacement uses the same ball-socket bracket system as the original. With the hatch supported by a prop or assistant, removing the old strut clips with a flathead screwdriver and snapping the new struts into place typically takes minutes per side.

• Recommended tools: flathead screwdriver and a prop or helper
• Tip: Always support the hatch before removing old struts to avoid injury
