Common Uses
- Weak or failing lift support on a Smart Fortwo rear hatch or access panel

- Loss of holding force in a gas spring assembly
- Noise or binding caused by worn socket connections
- Replacement for a gas strut with the same length and force specifications
Installation Notes
Verify the compressed length, extended length, force rating, and socket-style end fittings before installation. Compare the existing strut to Stabilus 4B-908463 and confirm the 10 mm attachment diameters match the vehicle mounting points. Replace one side at a time only if the original application uses a single support; otherwise match the vehicle’s original configuration. Check that the mounting sockets fully seat on the ball studs before returning the panel to service.
