Yes, the fifth wheel can be converted to a gooseneck.

The fifth wheel to gooseneck converter is a quick and easy option if you have got a 5th Wheel travel trailer and your tow vehicle already has a gooseneck hitch.

How to Know What Size Gooseneck Adapter Do I Need?

On a level trailer, estimating the length from the truck bed to the kingpin plate is a common mistake. Instead, take a measurement from the gooseneck ball’s top to the kingpin plate.

The reason for this is that when you buy any gooseneck adapters, the height of the adapter is measured from the top of the adapter to the inside of the hole on the bottom of the adapter.

The whole height of the gooseneck adapter device is not included in the measurements.

If you measured the outside of the gooseneck adapter with a tape measure, it would be larger than its rating.

When taking measurements, take notes of the trailer’s turning radius and the truck’s height over the bedrails.

Start by reckoning from the top of the gooseneck ball to the bottom of the king pin plate on your trailer.

When taking measurements, make sure your truck & trailer both are on the same level ground. In case the vehicle and trailer are not connected, measure the heights of the hitch ball & coupler.

Next, take measurements from the ground to the top of the gooseneck ball, and from the ground to the bottom of the king pin plate again. Your adapter offset size will be defined by the difference among these dimensions.

Also, from the top of the gooseneck ball to the trailer, assure you have 4-6 inches of clearance above the bedrails.

Using this measurement, figure out how tall of a gooseneck adapter you’ll need.

The majority, on the other hand, have 6-8 inch height adjustments.

How Does the 5th Wheel to Gooseneck Adapter Work?

The 5th wheel to gooseneck adapter is a unique hitch that links to the tow vehicle’s standard gooseneck ball and is mounted in the truck bed. The ball is then raised to a position where a little block on the kingpin is placed, allowing it to attach to the gooseneck ball.

All are special metal tubes with one end that links directly to the fifth wheel trailer’s kingpin and the other end that connects to a truck bed’s gooseneck ball.

This keeps your truck’s existing gooseneck hitch in place and prevents the need for a fifth-wheel hitch.

5th Wheel to Gooseneck Adapter Buying Guide

Gooseneck Adapters Buying Guide

When picking a 5th wheel to gooseneck adapter, there are a few things to keep in mind. Calculable and visible factors determine the best selection criteria.

Check through the categories below to get a better understanding of what you’re looking for in a perfect model:

Types of Adapters

To begin, make sure your heavy trailer is level. As previously stated, certain adapters are sold with a fixed height while others are adjustable. Although adjustable ones provide greater flexibility in ensuring a precise fit, they are also the most expensive.

As a result, the best option will be determined by your budget. Determine the adapter sizes necessary for your project if you opt to buy a fixed height adapter.

Sizes of Adapters

You’ll need to have the appropriate specifications, except you get an adapter that totally substitutes the trailer pin box. To find the right adapter size, measure the distance between the gooseneck ball’s tip as well as the pin box bottom.

Although most models come with built-in height adjustments, you should be aware of products that don’t.

  • For 11-inch to 12-inch measurements, a 12-inch adapter
  • For 13-inch to 14-inch measurements, a 15-inch adapter
  • For 15-inch to 16-inch measurements, a 17-inch adapter is required.

Types of Setup

Adapters aren’t all made equal. The way the adapter is mounted has a direct impact on the level of security.

Make a note of the setting type and its key nature in this table for easy reference.

Setup AAdapter replacing the trailer pin boxSuperior
Setup BAdapter replacing the 5th wheel hitchExcellent
Setup CThe adapter bolted over the king pin lube plateAverage


Adapters to convert a fifth wheel to a gooseneck cost between $400 and $500.

The cost is soon justified when you consider that they are made of solid steel and are among the few important linkages connecting your fifth wheel trailer and truck.


The majority of retail items come with extra features.

However, some items have fundamental functions that are marketed separately. Two to three of each of these accessories should be included in every model.


Consider having padlocks that lock the couplers as well as safety chains.

-Safety chains

Some states need chains for gooseneck hitches. Nonetheless, the chains are important safety features for both you and your family!


Cushioned adapters are also a good option because they provide a smoother ride.

-Remote release

Lastly, a remote release feature is a great feature because it eliminates the need to climb into the bed of your truck to unhook the hitch. Using a handle connected to a steel cable, you can release the hitch with a remote release.

How to Install Gooseneck Fifth Wheel Adapters?

The process of installation is usually simple. Because of its weight, having a friend hold the adapter in the air while attaching it to the trailer will be helpful.

The majority of individuals have discovered that they can install it and draw the trailer in 30 minutes.

Although most instructions don’t mention it, a little Loctite (the removable kind) can help ensure that the bolts don’t shake free over time, and it’s probably not a bad idea. It’s a low-cost form of peace of mind.

Installing an adapter is, therefore, less expensive and easier than changing the truck’s gooseneck with a fifth-wheel hitch.

Is It Safe to Use Gooseneck Fifth Wheel Adapters? (Safety Guide)

Gooseneck Fifth Wheel Adapters Safety Guide

Adapters connecting the 5th wheel to gooseneck hitches are generally considered safe, but they’re not ideal for long-term use. 

Avoiding hauling heavy loads is a way to make gooseneck adapters safe. You’ll remain under the weight limit and also have a safer experience if you have got a 12,000-pound 5th wheel and utilize an adapter rated for 20,000 lbs of gross trailer weight.

Gooseneck 5th wheel adapters that used the tube to attach to the kingpin, on the other hand, can place undue strain on the trailer’s frame, potentially voiding the warranty. This is because when tugging from a low point, they provide a torsion force to the kinpin.

Seeking professional advice on this will guarantee that it is used safely.

Because their shape is comparable to that of a standard fifth-wheel gooseneck connection, gooseneck adaptor hitches & gooseneck pin boxes don’t really generate frame stress.

While gooseneck adapters are generally safe, you don’t want to take any chances. You must decide whether or not a gooseneck adapter is appropriate for your purpose and, if so, which sort of gooseneck adapters are most appropriate.

A 5th wheel hitch moves and glides with the trailer to create less stress on the truck and trailer. However, gooseneck adapters are rigid. Long-term use can cause strain on the trailer or the tow vehicle. But these adapters are safe in a pinch and for short-term use.

Keep in mind that using one of these gooseneck adapters may void your fifth wheel trailer’s warranty because of the damage it can do to the frame. If you’re planning on using gooseneck hitches long-term, consider swapping out your trailer’s pin box for a gooseneck one instead.

What to Replace? Pin Box Or The Fifth Wheel Hitch?

That is generally determined by whether you own a fifth wheel trailer or a tow vehicle truck first.

If you already have a truck with a gooseneck hitch placed in the cargo bed frame, replacing the trailer’s pin box is typically less expensive.

Though there is technically a third alternative of bolting an adapter over the kingpin’s grease plate, an adapter that substitutes the fifth wheel hitch provides a more secure connection. However, it takes up more space and isn’t a realistic solution for short bed trucks.

On the other hand, replacing the fifth wheel trailer’s pin box is significantly easier and often less costly. However, you must realize that it will require more periodic maintenance, and if you install it yourself, you risk voiding the fifth wheel trailer’s guarantee.

You get a very secure connection, a bit lesser maintenance, and an arguably smoother ride with an adapter mounted over the king pin lubrication plate.

Frequently asked question FAQs:

Gooseneck Fifth Wheel Adapters FAQs

Based on our research from different forums we’ve answered the FAQs. We hope it’ll help to answer the critical questions.

Do I Need To Remove the Gooseneck Hitch Adapter?

If you plan to use gooseneck hitches long-term, the wisest option would be to replace your 5th wheel trailer’s pin box with a gooseneck pin box.

You can find many kinds of hitches, adapters, and combinations. If you feel unsure, consult with a professional for recommendations specific to your situation.

Which is stronger: gooseneck or fifth wheel?

Gooseneck hitches can pull more than 30,000 pounds, at least 3,000 pounds more than the best fifth wheel hitch, which makes them great for agriculture and commercial work.

Can you tow a fifth wheel with a 6.5 foot bed?

Yes, a best fifth wheel with a 6.5-foot long bed can be towed with sliding hitches. Sliding trailer hitches are very similar to regular 5th wheel trailer hitches.

Can you pull a gooseneck trailer with a bumper hitch?

The answer is yes and no. This means you can, but it would be unsafe to do so.

A bumper hitch’s vertical load rating is typically exceeding. The entire purpose of a gooseneck trailer is about being able to load more weight onto the truck, resulting in a greater capacity than a bumper pull with about the same axles.

What kind of truck can pull a gooseneck?

The Dodge Ram, the Ford F-Series Super Duty, and the GMC Sierra HD are the cream of the crop for heavy duty trucks for towing. They offer the highest bumper payload capacity, the best gooseneck options, and the most torque on the market.

Is a gooseneck better than a bumper pull?

Both of them serve their purpose well. Typically, Goosenecks are a more stable choice than a bumper pulls, as more of the weight is over the vehicle’s rear axle than behind it. This implies the trailer will sway less at faster speeds and the weight limit will be increased.

Other trailer types can’t turn as tight as a gooseneck trailer hitch. A bumper pull trailer is definitely the appropriate trailer for you if you’re searching for a tiny, economical trailer which you can tow behind vehicles such as SUVs or RVs.

Gooseneck hitches, on the other hand, should be your pick if you need a trailer with a huge towing capacity, or have a truck and want a smoother, more stable ride.


Now that you know about our top 5 best 5th wheel to gooseneck adapters and everything about 5th wheel gooseneck adapters, you’re better positioned to decide which one will be the best option for you.
