Detailed Description
Stabilus 3F-7778BZ is a direct-fit gas spring specified for the left side on 1983-1986 Porsche 944, 1988 Porsche 944, 1990-1991 Porsche 944, and 1992-1995 Porsche 968.

What It Helps Address
- Weak or failing lift support on the left side
- Hatch, lid, or panel that drops too quickly
- Reduced opening assistance from a worn gas strut
- Inconsistent support position during service access
- Noise or rough movement caused by an aging strut
Installation Notes and Tips
Verify left-side placement before installation and compare the compressed length, extended length, and attachment style to the original unit. Confirm the plastic socket connections and 10 mm end attachment diameter match the vehicle mounting points. For best results, replace the support only after checking hinge condition and mounting wear, since excess play can affect performance.
