Installation (Setup)
Installation of the BDFHYK gas struts is designed to be straightforward. You will primarily need a flat screwdriver for the removal of existing supports. For safety, it is highly recommended to have assistance to hold the hood, tailgate, or glass window while replacing the lift support, as the struts have strong internal force.
Required Tool:
- Flat screwdriver
Installation Steps:
- Remove the Old Support: Place a small flat screwdriver under the U-shaped band of the end fitting on the old support. Gently lift the band to release the support from the ball stud.
- Pull Out Old Support: Once the U-band is lifted, carefully pull the old support out from the vehicle's mounting point.
- Install New Support: Align the ball socket of the new strut over the ball stud on your vehicle. Push it firmly and carefully until it locks into place. You should hear a click or feel it secure.
- Repeat for Other Side: Install the second strut following the same procedure.
Online installation videos are available for further visual guidance if needed.

Operation
Once installed, the BDFHYK gas shocks struts provide smooth and consistent lift assistance. They are designed to hold the supported component (e.g., camper shell window, trunk lid) securely in the open position and allow for controlled closing. The internal gas spring mechanism ensures a soft and quiet operation, similar to original equipment.
Maintenance
The BDFHYK gas shocks struts are engineered for durability and require minimal maintenance. They feature a double seal ring to prevent air leakage and a high gloss oil layer process to prevent moisture and rust, ensuring long-term performance.
- Regular Inspection: Periodically inspect the struts for any signs of damage, corrosion, or leakage. Ensure the mounting points are secure.
- Cleaning: Keep the struts clean from dirt and debris. Wipe them with a damp cloth if necessary. Avoid using harsh chemicals that could damage the finish.
- Avoid Compression by Hand: Do not attempt to compress the struts by hand, as this can damage the internal mechanism and is not indicative of their operational force.

Troubleshooting
If you encounter issues with your BDFHYK gas shocks struts, consider the following common problems and solutions:
- Struts Not Holding Weight:
- Ensure you have selected the correct force (Lbs/N) for your application. The ML1310 provides 10 Lbs of support per strut. Heavier applications may require higher force struts.
- Verify that both struts are installed correctly and securely.
- Check for any signs of damage or leakage on the strut body.
- Stiffness or Noise During Operation:
- New struts may require a few cycles to operate smoothly.
- Ensure the mounting points are clean and free of obstructions.
- Verify that the struts are not binding or rubbing against any surrounding components.
- Incorrect Fitment:
- Double-check the extended and compressed lengths against your original struts or application requirements. The ML1310 has an extended length of 15 inches and a compressed length of 9.5 inches.
- Confirm that the end fittings (ball sockets) are compatible with your vehicle's ball studs. These struts are designed to fit OE brackets.
- Refer to the OE number compatibility list in the Specifications section to ensure it matches your vehicle's requirements.
