how to install gas struts on a lid

Installing gas struts (also known as gas springs or lift supports) on a lid is a useful way to make opening and closing the lid easier and more convenient. Gas struts are commonly used on car hoods, trunks, toolboxes, and other applications where controlled lid movement is desired. Here’s a general guide on how to install gas struts on a lid:

Materials You’ll Need:

  • Gas struts with mounting brackets (appropriate length and strength for your lid)
  • Mounting hardware (screws, bolts, nuts)
  • Screwdriver or drill with the appropriate bits
  • Socket set or wrenches
  • Measuring tape
  • Level (optional, for alignment)
  • Safety goggles and gloves


  1. Safety Precautions:
    • Put on safety goggles and gloves to protect your eyes and hands during the installation process.
  2. Select the Right Gas Struts:
    • Choose gas struts that are appropriate for your lid’s weight and size. Refer to the manufacturer’s specifications or guidelines for guidance. Make sure you have two gas struts for balanced support.
  3. Determine Mounting Locations:
    • Examine your lid to determine where you want to mount the gas struts. Typically, you’ll want to mount them on each side near the hinge or pivot points. Ensure that the mounting locations are structurally sound and can support the struts.
  4. Measure and Mark:
    • Measure and mark the exact locations where you’ll attach the mounting brackets for the gas struts. Use a level to ensure that the marks are aligned properly.
  5. Attach Mounting Brackets:
    • Securely attach the mounting brackets to the marked locations on your lid using screws or bolts. The type of hardware you use will depend on the material of your lid (e.g., wood, metal, plastic).
  6. Attach Gas Struts to Brackets:
    • With the mounting brackets in place, attach one end of each gas strut to a bracket on the lid. Most gas struts have ball-and-socket connectors that snap into place. Ensure they are securely attached.
  7. Determine Attachment Points on the Base:
    • Now, determine where you will attach the other ends of the gas struts on the base or frame where the lid will be mounted. These attachment points should align with the lid brackets when the lid is closed.
  8. Attach Gas Struts to the Base:
    • Attach the other ends of the gas struts to the base or frame using the provided hardware. Make sure they are securely fastened.
  9. Test the Gas Struts:
    • Carefully open and close the lid to test the gas struts. They should assist in lifting the lid when opening and provide controlled resistance when closing. If necessary, adjust the mounting locations for optimal performance.
  10. Secure All Hardware:
    • Double-check that all screws, bolts, and nuts are securely tightened. Loose hardware can lead to a malfunction of the gas struts or pose a safety hazard.
  11. Final Inspection:
    • Inspect the entire installation to ensure that the gas struts are functioning correctly, and that there are no loose or misaligned components.
  12. Maintenance:
    • Periodically inspect and lubricate the gas struts as recommended by the manufacturer to prolong their lifespan and maintain performance.

Installing gas struts on a lid can greatly improve its functionality and ease of use. Always refer to the manufacturer’s instructions and guidelines for the specific gas struts you are using, as installation methods may vary slightly depending on the brand and model.
