Setup and Installation
Installation of StrongArm lift supports is typically straightforward and can be completed with simple hand tools. This guide focuses on ball socket installations. For bracket supports, refer to specific instructions provided with your purchase.
- Prepare the Area: Ensure the vehicle component (hood, hatch, etc.) is safely propped open and secured to prevent accidental closure during the process.
- Remove Old Supports:
- Locate the attachment points of the old lift support.
- Using a small flat-head screwdriver or similar tool, carefully pry open the retaining clip on the ball socket end of the old support.
- Once the clip is disengaged, pull the old support off the ball stud. Repeat for both ends.
- Install New Supports:
- Align the new StrongArm lift support's ball socket end with the corresponding ball stud on the vehicle.
- Firmly push the socket onto the ball stud until it clicks into place. Ensure the retaining clip is fully engaged.
- Repeat for the other end of the lift support.
- Install one support at a time. Once the first new support is installed, remove the prop and install the second support.
- Test Operation: Gently open and close the component to ensure the new lift supports function correctly and hold the component securely in the open position.

Operating Instructions
StrongArm 4418 Universal Lift Supports are designed to assist in the opening and holding of various vehicle components. Once installed, they will provide the necessary force to lift and maintain the open position of the component, such as a hood, hatch, or trunk lid.
- Opening: Begin to lift the component manually; the lift supports will engage and assist in the full opening motion.
- Holding: The supports will hold the component securely in its fully open position, allowing for safe access.
- Closing: Apply gentle downward pressure to close the component. The supports will compress smoothly.

Maintenance
To ensure the longevity and optimal performance of your StrongArm lift supports, follow these simple maintenance guidelines:
- Regular Inspection: Periodically inspect the lift supports for any signs of damage, corrosion, or leaks. Check the attachment points for secure connections.
- Keep Clean: Wipe down the shafts of the supports with a clean, damp cloth to remove dirt and debris. Avoid using harsh chemicals or abrasive cleaners.
- Avoid Obstructions: Ensure that nothing obstructs the smooth operation of the supports when opening or closing the component.
Troubleshooting
If you encounter issues with your StrongArm 4418 Universal Lift Supports, consider the following:
- Component Does Not Stay Up:
- Ensure both lift supports are correctly installed and securely attached to the ball studs.
- Verify that the correct lift supports for your application have been installed. Incorrect force ratings can lead to insufficient holding power.
- If the supports are old, they may have lost gas pressure over time and require replacement.
- Noisy Operation (Squeaking/Grinding):
- Check for any debris or corrosion on the shaft or at the pivot points. Clean as necessary.
- Ensure the ball sockets are properly seated and not binding.
- Difficulty Opening/Closing:
- If the component is unusually stiff, check for obstructions or misalignment.
- Ensure the supports are not bent or damaged.
If troubleshooting steps do not resolve the issue, contact StrongArm customer support or a qualified technician.
