Best 5th Wheel To Gooseneck Adapters

Best 5th Wheel To Gooseneck Adapters

There are two known types of trailer hitches – the fifth wheel hitches and the gooseneck. They both serve the purpose of effectively allowing a pickup truck to haul several thousand pounds (lbs) of wheeled cargo. The fundamental differences between the two are its basic mechanical structures.

In essence, you cannot link a trailer king pin onto a truck with a gooseneck hitch. The logical solution for this scenario is to completely replace your gooseneck hitch. But you may not really want to surrender its advantage in terms of truck bed space – especially if you can detach and reattach the gooseneck ball to its mounting socket.

Apart from the truck bed’s space and versatility, another drawback of shifting to a fifth wheel hitch is that you may need to take your vehicle to a garage to safely dismantle the mounting system around or under the bed. Instead of going through the effort and financial expenses, a sound alternative is to just simply install an adapter. A hitch adapter anatomically modifies the trailer’s king pin or pin box in order to lock itself effectively into a gooseneck hitch.

Essential Selection Factors

There are a few key factors you need to consider when choosing a 5th wheel to gooseneck adapter. The ideal selection criteria are determined by calculable and observable elements. Check out the following categories to have a better idea of choosing a perfect model:

Adapter Sizes

Unless you buy an adapter that completely replaces the trailer pin box, you need to get the right measurements. To get the ideal adapter size, you must compare the gap between the tip of the gooseneck ball and bottom of the pin box. Although most models have built-in height tweaks, you ought to be wary of choosing products without that advantage.

  • 12-inch adapter for 11-inch to 12-inch measurement
  • 15-inch adapter for 13-inch to 14-inch measurement
  • 17-inch adapter for 15-inch to 16-inch measurement

Setup Types

Not all adapters are created the same. In fact, how the adapter is installed can have a direct bearing on the level of security when you tow a modified fifth wheel connector to a gooseneck ball truck hitch. For easier reference, take note of the setup type and its basic characteristics in this table:

Setup AAdapter replacing the trailer pin box
Safety LevelSuperior
Setup BAdapter replacing the 5th wheel hitch
Safety LevelExcellent
Setup CAdapter bolted over the king pin lube plate
Safety LevelAverage

Retail Price

Another factor that potentially seals the deal when it comes to your selection is the retail price. The fifth wheel to gooseneck adapter entails an average cost between $400 and $500. Anything lower is than that price range is considered cheap while anything exceeding it is considered expensive.


Most retail items come with additional features. However, there are products wherein some basic features are sold separately. Every model ought to contain 2 to 3 of all these accessories:

  • Padlocks
  • Safety chains
  • Cushioning
  • Remote release
