Detailed Description

Stabilus 4B-0406IS is a gas-charged lift support engineered for consistent motion control in select Volvo body applications. The 545 mm extended length, 313.5 mm compressed length, and 320 N force rating provide the dimensions and load support needed for proper hatch or panel operation. This part number 4B-0406IS is listed for 1997-1998 Volvo V90, 1992-1997 Volvo 960, 1991-1995 Volvo 940, 1986-1992 Volvo 740, 1983-1990 Volvo 760, and 1985 Volvo 745.

This part cross-references Monroe Shocks & Struts (e.g., 901159) for the same application.

What It Helps Fix

• Weak or failing lift support pressure
• Rear hatch or panel that drops too quickly
• Difficulty holding an open position
• Uneven or inconsistent opening effort
• Noise or reduced control from worn gas struts

Installation Notes and Tips

Verify the original support’s compressed length, extended length, force rating, and end fittings before installation. Match the plastic socket connections and 10 mm attachment diameter to the vehicle’s existing mounting points. For best results, replace supports in pairs when both sides are worn, and confirm smooth operation after installation on Volvo V90, 960, 940, 740, 760, or 745 applications.

Quality Assurance

Stabilus is a recognized OE supplier of gas springs and lift supports, and this part is built to match the dimensional and force requirements listed for the application.
