Detailed Description

Stabilus 5B-499514 is engineered to match the dimensions and force output needed for a specific BMW Z4 application. With a 570 N force rating, 283 mm extended length, and 193.5 mm compressed length, this gas spring is specified for consistent support and controlled movement in the vehicle’s lift or access panel system. The plastic socket connection style helps maintain OE-type mounting geometry and simplifies replacement when the original support loses pressure.

Fits 2009-2016 BMW Z4, N/A. This part cross-references Tuff Support 614168 for the same application.

What It Helps Fix

• Weak or failing lift support that no longer holds position
• Hatch, lid, or panel movement that feels heavy or uncontrolled
• Slow or uneven opening caused by loss of gas pressure
• Noise or instability from worn support hardware interfaces

Installation Notes and Tips

Verify the compressed length, extended length, rod diameter, tube diameter, and socket style against the original support before installation. Confirm the mounting points are clean and free of damage so the plastic socket ends seat properly. For best results, replace supports in matched applications only when the vehicle design calls for it, and compare the removed unit to part number 5B-499514 before final fitment.

Quality Assurance

Stabilus is a recognized OE supplier for gas springs and lift supports, and this replacement is built to the listed dimensional and force specifications for the BMW Z4 application.
