Detailed Description

What It Helps Address

• Rear liftgate that drops too quickly
• Hatch that no longer stays open securely
• Weak or worn gas strut performance
• Uneven or inconsistent liftgate support
• Noisy or sluggish rear hatch operation

Installation Notes and Tips

Verify the vehicle’s model year and audio-system configuration before installation, since fitment is limited to Toyota Sienna vehicles with a 10 speaker audio system. Compare the original strut’s extended length, compressed length, rod diameter, tube diameter, and end connections to confirm match before removal. Support the liftgate securely during replacement and transfer the mounting points carefully to avoid damage to the plastic sockets.

Stabilus is a recognized OE supplier for gas springs and lift supports, and this part is built to the listed dimensional and force specifications for the confirmed Toyota Sienna applications. Part number 3B-291620 should be matched to the vehicle fitment data above for accurate replacement selection.
