Detailed Description
This Stabilus gas spring is engineered for select Toyota Prius Prime lift support applications and matches the OE-style dimensions needed for proper travel and mounting alignment. The 4B-929988 cross-references common replacement numbers including 68950-0WB20 and 68960-0WB20, making it a practical choice when replacing a worn support on a 2017-2020 Toyota Prius Prime or a 2021 Toyota Prius Prime built to 08/2020. The plastic socket ends simplify attachment to the original mounting points while maintaining the specified force output.
Use this gas spring when the original support no longer holds position, opens too quickly, or loses lift assistance over time. Confirm the compressed length, extended length, rod diameter, tube diameter, and socket-style ends against the original unit before ordering. Stabilus 4B-929988 is a fitment-specific replacement for Prius Prime lift support service, not a universal gas strut.
What It Is Used For
- Restoring lift support on a Toyota Prius Prime hatch, hood, or panel application using the listed OE fitment
- Replacing a weak gas spring that no longer holds the panel open
- Correcting slow, uneven, or abrupt opening action
- Addressing worn socket connections that no longer seat securely
- Replacing a support with incorrect length or force rating
Installation Notes and Tips
Verify the vehicle year and build date before installation: this part fits 2017-2020 Toyota Prius Prime and 2021 Toyota Prius Prime to 08/2020. Match the original mounting style, overall length, and force rating before removing the old support. Support the panel securely during service and inspect the mounting balls or sockets for wear before snapping the new gas spring into place.
