What Is a 5th Wheel Gooseneck Adapter and Why Would You Use One?
Created at : Apr 8, 2025If you have a fifth-wheel trailer, most people think you have to have a traditional fifth-wheel hitch setup. But what if your truck already has a gooseneck hitch installed? That’s where a 5th wheel gooseneck adapter comes into play. This handy device bridges the gap between fifth-wheel trailers and gooseneck hitches, making it easier and more affordable to get on the road.
What Does a 5th Wheel Gooseneck Adapter Do?
A fifth-wheel gooseneck adapter allows a fifth-wheel trailer—which normally connects to a large, plate-style hitch in the bed of a truck—to connect to a gooseneck ball hitch instead. Gooseneck hitches are typically installed for towing horse trailers, equipment haulers, or flatbeds. If your truck has a gooseneck setup, the adapter saves you the hassle and cost of installing a dedicated fifth-wheel hitch.
Why Use a Gooseneck Adapter?
There are several good reasons to consider using a gooseneck adapter:
- Cost Savings: Fifth-wheel hitches can be pricey and may require professional installation. A gooseneck adapter is often a more affordable alternative.
- Bed Space: Fifth-wheel hitches take up a lot of space in your truck bed. A gooseneck ball hitch and adapter are easier to remove, leaving your bed open for other uses.
- Convenience: If you regularly switch between towing a gooseneck trailer and a fifth-wheel trailer, using an adapter eliminates the need to swap hitches.
How It Works
The adapter attaches to the king pin on your fifth-wheel trailer and extends down to the gooseneck ball in your truck bed. Depending on your needs, there are several styles available:
- Bolt-On or Weld-On Adapter Tubes: These permanently attach to the trailer’s king pin.
- Cushioned Adapters: Designed to absorb road shock and reduce stress on the trailer frame.
- Offset Adapters: Offer extra clearance for short-bed trucks to help with tighter turns.
Important Considerations
Before buying or installing a gooseneck adapter, keep these points in mind:
- Towing Capacity: Always verify that the adapter is rated for your trailer’s weight.
- Manufacturer Warranty: Some trailer manufacturers void the warranty if you use an adapter instead of a proper fifth-wheel hitch. Be sure to check your trailer’s documentation.
- Ride Quality: While convenient, gooseneck adapters may transfer more vibration and stress to the trailer frame. Cushioned models are a good option to mitigate this.
Final Thoughts
A 5th wheel gooseneck adapter is a great solution for those looking to tow a fifth-wheel trailer with a truck that already has a gooseneck hitch. It's cost-effective, convenient, and easy to install—but it’s not a one-size-fits-all solution. Make sure to choose the right type of adapter for your setup and always keep safety and warranty concerns in mind.
