Detailed Description
This Stabilus gas spring is specified for 2004-2009 Mazda 3 models and is identified by part number 4B-016990. With a 540 mm extended length, 319 mm compressed length, and 390 N force rating, it is sized to provide controlled support for the application it was engineered for. The plastic socket attachment style on both ends helps match the original connection layout used on the vehicle.
This part cross-references AMS Automotive 6371 and Wix 46371 for the same application. If you are replacing a worn lift support on a Mazda 3, 4B-016990 is the reference number to verify against the original unit before ordering.
Common Replacement Reasons
- Lift support no longer holds the panel, hatch, or lid in position
- Opening action feels weak, uneven, or slow
- Closing action drops too quickly
- Original gas spring shows loss of pressure or reduced support
- Replacement needed for a 2004-2009 Mazda 3 lift support application
Installation Notes and Tips
Confirm the compressed length, extended length, force rating, and socket-style end fittings before installation. Compare the original support to 4B-016990 to verify rod diameter, tube diameter, and attachment style match the vehicle. Install with the vehicle-supported component secured so the panel cannot fall during removal.
