Product Description

Use this gas spring when the original lift support no longer holds position, drops too quickly, or feels weak during opening and closing. The 10 mm rod and 22 mm tube dimensions, along with the 399.5 mm compressed length and 668.5 mm extended length, help ensure proper fitment on the specified Buick Century, Buick Skylark, Chevrolet Nova, Oldsmobile Omega, and Pontiac Phoenix applications. The Stabilus 3B-198171 is a practical OE-style replacement for restoring controlled motion to supported panels.

Common Issues This Part Can Address

• Liftgate, hatch, or hood no longer stays open
• Support drops faster than normal when raised
• Original gas spring has lost pressure
• Uneven or inconsistent opening and closing effort
• Worn socket ends causing poor support performance

Installation Notes and Tips

Verify the compressed length, extended length, force rating, and metal socket end style against the original support before installation. Compare the removed part to the Stabilus 3B-198171 and confirm the mounting points on the vehicle match the listed application. For best results, replace gas springs in pairs when both sides are worn, and support the panel securely before removing the old unit.
