AiYiGu Rear Hatch Struts for 2004–2009 Toyota Prius — 2-Piece Replacement Pair, Direct-Fit Gas Shocks

AiYiGu 4094 rear hatch struts are a pair of replacement gas shocks engineered to restore smooth, secure lifting and holding of the rear hatch on 2004–2009 Toyota Prius models.

If your Prius rear liftgate drops, opens unevenly, or no longer stays up, these two AiYiGu replacement hatch shocks bring back reliable support using direct-fit dimensions and common OEM part cross-references. The set includes left and right struts sized to match the original geometry — compressed length 12.04 inches and extended length 19.74 inches — and they install without additional fasteners. Backed by a two-year warranty from AiYiGu, the pair replaces OEM numbers such as 4094, PM2039, SG329018, SG329019, and related Toyota part codes.

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

These hatch shocks are designed specifically for the second-generation Prius (model years 2004–2009) and align with common OEM part numbers used on those vehicles. They match the factory mounting points and overall stroke so no custom modifications are required.

• Compatible years: 2004, 2005, 2006, 2007, 2008, 2009 Prius.
• Cross-references: 4094, PM2039, SG329018, SG329019, 68950-0W204, 68960-0W193, 68960-0W194.
• Pair includes both left and right struts for a complete replacement.

What is involved in installing these replacement hatch shocks?

Installation is straightforward and does not require special fasteners: the original ball-socket clips are reused and the new struts snap into place. Use a flathead screwdriver to release the old bracket clips and support the hatch with a prop or helper before removal to avoid injury.

• No screws or bolts included; uses existing ball-socket mounts.
• Recommended tools: flathead screwdriver and a prop or assistant to hold the hatch.
• Typical install time: 10–25 minutes for both sides, depending on experience.

How do these specifications affect performance and longevity?

The specified compressed and extended lengths ensure correct lift angle and secure holding force when the hatch is open. Built to replace worn OEM shocks, they restore proper gas-pressure support and reduce sudden drops and heavy slamming.

• Compressed length: 12.04 inches; extended length: 19.74 inches for correct geometry.
• Engineered to match factory stroke for consistent hatch travel and hold.
• Sold as a two-piece set to replace both sides and balance lift force.

Who this is for: Owners of 2004–2009 Toyota Prius vehicles who want a cost-effective, direct-fit replacement for sagging or failed rear hatch supports. This pair is ideal for do-it-yourselfers and mechanics needing OEM-compatible lengths and part-number cross-references, plus anyone seeking a covered replacement under a two-year AiYiGu warranty. If you require the original mounting hardware, note that screws or new brackets are not included; the design assumes reuse of your vehicle’s existing ball-socket mounts.
