Detailed Description
This Stabilus gas spring is engineered to match the specified lift support geometry for 1994-1997 Volvo 850 and 1998-2000 Volvo V70 applications. The 5B-3958IA uses metal socket ends and OE-style dimensions to support controlled opening and holding force for rear liftgate or hatch operation. If you are replacing a worn support on a Volvo 850 or Volvo V70, this part number provides the correct length and force specification for the listed vehicles.
This part cross-references Timken 614174 and URO 9485548 for the same application.
What This Part Helps Address
- Weak or failing liftgate support
- Hatch that drops instead of staying open
- Uneven or slow rear opening action
- Loss of holding force in cold or aging conditions
- Noise or instability from worn gas struts
Installation Notes and Tips
Verify the compressed length, extended length, and end connection style before installation. Compare the existing support on the vehicle to the 5B-3958IA dimensions and metal socket attachment points to confirm proper fitment. Replace supports in matched condition when the opposite side shows similar wear, and support the hatch or liftgate securely during removal and installation.
