Technical Details and Construction

The StrongArm 4499 gas strut features a robust steel outer cylinder finished in black for corrosion resistance and longevity. The 19.0 mm diameter cylinder houses an 8.0 mm inner shaft designed to provide smooth extension and retraction over a 7.92-inch stroke. Both ends are equipped with 10mm nylon ball socket fittings, ensuring secure attachment points compatible with specific vehicle mounts. The inclusion of rubber and Teflon materials enhances sealing and reduces friction, contributing to consistent force output rated at 175 Newtons.

Compatible Vehicle Applications

This gas strut is designed for specific fitment rather than universal use. It is commonly compatible with certain makes and models requiring a gas spring with these exact dimensions and force ratings. For example, it suits applications in mid-size sedans and compact SUVs where a 19.69-inch extended length and 11.77-inch compressed length are required. Always verify fitment with your vehicle’s OEM specifications before installation.

Common Uses and Problem Resolution

• Supports liftgate or hatchback opening and closing
• Replaces worn or leaking gas springs causing sagging or difficulty in operation
• Restores smooth motion in trunk or hood struts
• Eliminates rattling or loose end fittings in existing struts
• Provides consistent force to maintain component position during use

Installation Notes and Tips

Installation of the StrongArm 4499 gas strut requires matching the ball socket ends to the vehicle’s mounting points. Ensure the mounting brackets are clean and free of debris before attaching. Use appropriate tools to snap the nylon ball sockets securely onto the vehicle’s ball studs. Avoid forcing the strut beyond its stroke length to prevent damage. It is recommended to replace gas struts in pairs to maintain balanced support.
