This StrongArm gas strut (part number 6291) is constructed with a steel outer cylinder finished in black for corrosion resistance and durability. The 19.0 mm cylinder diameter and 8.0 mm inner shaft diameter provide the strength needed for consistent performance. Both ends feature 10mm nylon ball sockets, allowing for secure attachment and smooth pivoting action. The absence of an internal rebound spring simplifies the design, focusing on reliable gas pressure support. Rubber and Teflon materials are incorporated to reduce friction and wear, extending the service life of the strut.

• Replaces worn or weak gas struts causing difficulty in opening or holding panels
• Eliminates rattling or loose movement in supported components
• Restores smooth and controlled lifting and lowering action
• Prevents sudden closure that can cause damage or injury

Installation Notes and Tips

When installing the StrongArm 6291 gas strut, ensure the ball socket ends align correctly with the mounting points on your Audi A4, A4 Quattro, or S4. Use appropriate tools to avoid damaging the nylon sockets. It is recommended to replace gas struts in pairs to maintain balanced support. Verify the compressed and extended lengths match the original parts for proper fitment. Lubricate pivot points if necessary, but avoid applying grease directly to the gas strut shaft.
