Detailed Description

Stabilus 4B-280617 is an OE-style gas spring with plastic socket end connections and a 10 mm end attachment diameter.

What It Is Used For

  • Replacing a weak or failed lift support that no longer holds the panel open
  • Restoring controlled opening and closing action
  • Addressing a liftgate, hatch, or hood that drops unexpectedly
  • Correcting uneven or inconsistent support force
  • Reducing strain when opening the rear or front panel on an INFINITI QX50

Installation Notes and Tips

Verify the original part number, compressed length, extended length, and socket-style end fittings before installation. Compare the existing support to 4B-280617 to confirm the 8 mm rod diameter, 22 mm tube diameter, and 540 N force rating match the vehicle application. Fits 2015-2017 INFINITI QX50, N/A.
