how to extend trailer tongue


Extending a trailer tongue involves increasing the length of the front part of a trailer, which includes the hitch and coupler. Extending the tongue can be a DIY project but requires careful planning and precise execution. Here’s a general guide on how to extend a trailer tongue:

Materials and Tools You May Need:

  • Trailer tongue extension kit (available at hardware or trailer supply stores)
  • Welding equipment or hitch extension hardware (depending on the method you choose)
  • Measuring tape
  • Angle grinder
  • Safety gear (gloves, welding mask, safety glasses, etc.)
  • Level
  • Adjustable wrench
  • Trailer jack and jack stands
  • Protective gear (for welding)


  1. Assess the Need for Extension:
    • Determine why you need to extend the trailer tongue. Common reasons include accommodating a longer boat, improving trailer balance, or providing clearance for a towing vehicle.
  2. Measure and Plan:
    • Measure the desired extension length for the tongue. Make sure to take into account the specific needs of your trailer and towing setup. The extension should meet your safety and towing requirements.
  3. Select a Method:
    • There are two primary methods for extending a trailer tongue: welding an extension or using a hitch extension kit. The choice depends on your welding skills and the type of trailer you have.
  4. Welding Method:
    • If you’re skilled in welding, you can fabricate a trailer tongue extension. This typically involves cutting the existing tongue and welding a new section of steel tubing in place. Ensure that the extension is securely welded and aligned properly.
  5. Hitch Extension Kit Method:
    • A hitch extension kit is a more straightforward option for those who aren’t experienced in welding. It involves attaching a pre-made extension to the existing tongue using nuts and bolts. Follow the manufacturer’s instructions carefully for installation.
  6. Safety Precautions:
    • Regardless of the method chosen, safety is paramount. Wear appropriate protective gear when cutting, welding, or using power tools. Follow safety guidelines for working with metal and welding.
  7. Extend the Wiring and Safety Chains (If Necessary):
    • If your trailer has wiring for lights and safety chains, you’ll likely need to extend them to reach the new hitch location. Use appropriate connectors and extension cables.
  8. Leveling and Testing:
    • Once the extension is in place, use a level to ensure that the tongue is level. Proper leveling is crucial for safe towing. Test the trailer with a light load to verify that it tracks correctly and doesn’t sway excessively.
  9. Inspect Regularly:
    • Periodically inspect the trailer tongue extension for signs of wear, damage, or stress. Ensure that all fasteners remain secure.
  10. Register the Changes (if required):
    • Depending on your location and the trailer’s specifications, you may need to register the changes with local authorities or the Department of Motor Vehicles.

Remember that extending a trailer tongue should be done carefully to maintain safe towing capabilities. If you’re unsure about any aspect of the process, it’s advisable to consult with a professional trailer technician or welding expert to ensure that the extension is secure and safe for towing.
