Application Details

It is a fitment-based replacement for select vehicle lift-support systems, including applications associated with Honda Civic and Acura Integra platforms where the OE gas spring uses the same length, force, and socket-style ends. For buyers searching by vehicle, Stabilus 4B-331997 is commonly referenced in Honda Civic and Acura Integra gas strut replacement searches.

What This Part Helps Address

• Weak or failing lift support on a hood, hatch, trunk, or access panel
• Panels that drop too quickly when opened
• Reduced holding force in cold weather or after long service life
• Uneven or inconsistent opening and closing motion
• Noise or binding caused by worn gas spring performance

Installation Notes and Tips

Verify the compressed length, extended length, force rating, and plastic socket connection style before ordering. Match the rod and tube end attachment diameters to the original part, and compare the OE part number when available. For fitment-based searches, confirm the vehicle application against the original gas strut used on the Honda Civic or Acura Integra platform before installation.
