What It Helps Fix

• Weak or failing lift support that no longer holds position
• Hood, hatch, trunk, or panel movement that drops too quickly
• Uneven or inconsistent opening effort
• Noise or binding caused by worn gas spring internals
• Loss of support on the listed Buick Century, LeSabre, Regal, and Riviera applications

Installation Notes and Tips

Verify the original compressed length, extended length, force rating, and socket-style end fittings before installation. Match the vehicle application exactly, including the 1999 Buick Regal note for vin # to 500771. Confirm that the mounting points accept 10 mm rod-end and 8 mm tube-end attachment diameters, and compare the removed part to the Stabilus 5B-249078 before final fitment.
