Detailed Description

Stabilus 4B-020534 is a gas spring engineered to match the dimensional and force requirements of specific vehicle lift-support applications. The 340 N output, 10 mm end attachment diameter, and plastic socket connections make it a practical replacement when the original support has weakened, lost pressure, or no longer holds a panel in position. This part number is commonly searched as a Stabilus 4B-020534 gas strut for OE replacement service, including applications tied to BMW and Mercedes-Benz lift support needs.

For buyers searching by vehicle fitment, this part is relevant to BMW and Mercedes-Benz applications where the original support uses the same length, force, and socket-style attachment design. Use the part number 4B-020534 when matching the original gas spring specification to avoid incorrect lift force or travel.

What It Helps Fix

• Weak or failing lift support on a hood, hatch, trunk, or rear panel
• Panels that drop too quickly when opened
• Support struts that no longer hold position
• Uneven opening effort caused by worn gas pressure
• Noisy or inconsistent panel movement from an aging strut

Installation Notes and Tips

Match the original compressed length, extended length, force rating, and end connection style before installation. Confirm that the vehicle uses plastic socket attachments and that the mounting points accept a 10 mm end diameter. Compare the removed strut to Stabilus 4B-020534 before installation to verify orientation and travel. For BMW and Mercedes-Benz fitment searches, confirm the exact application by part number rather than vehicle name alone.

Quality Assurance

Stabilus is a recognized OE supplier of gas springs and lift supports, and this part is built to OE-style dimensional standards for replacement use. Verify the original application details against the vehicle and removed component to ensure correct selection.
