B&W Turnoverball Gooseneck Trailer Hitch

B&W Turnoverball Gooseneck Hitch

Not only does this kit provide you with a sturdy, custom base for installing your Companion fifth-wheel trailer hitch in the bed of your truck, but it also doubles as one of the most recognizable gooseneck hitches on the market. This fifth wheel installation kit actually is the Turnoverball gooseneck hitch from B&W.


Gooseneck Specs:

  • Gross towing weight: 30,000 lbs
  • Vertical load limit: 7,500 lbs
  • Ball size: 2-5/16"

B&W Companion Installed in Turnoverball Gooseneck Hitch

With the B&W Turnoverball underbed gooseneck trailer hitch you get the best of both worlds. When you go to tow a gooseneck trailer, the Turnoverball creates a sturdy, dependable connection with your trailer. And when you're done towing, you can stow the ball upside down in the hitch to get full bed access and a clean appearance. When you're ready to tow your fifth wheel trailer, just install the Companion in the ball hole in place of the gooseneck ball and lock the post in place using the built-in handle. You can remove the fifth wheel when you're done towing, leaving your truck bed open once again.


Simple, Custom Installation

This kit is custom designed for your vehicle. The mounting brackets bolt to existing holes in your truck's frame. While some modification is required - you will need to cut a 4" diameter hole in your bed for the hitch ball and drill holes for the built-in safety chain loops - there is no need to weld onto or to drill into your frame.


Once you have the brackets and center section installed, set up the operating handle. This handle is designed to be accessed from the rear driver's-side wheel well. On the end of the handle is the heavy-duty steel pin that secures the mounting post of the Companion (or the base of the gooseneck hitch ball).

Great Product !!!!!!!!!!!!!!!!!!!!!!!! I have hauled my large 42 foot 5th wheel across the country with this hitch and the B&W companion 5th wheel hitch. Best in the world I love it very quit and stable!!!!!!!!!!!!!!! Great job guys at B&W and thank you etrailer for selling the best product!



by:
2016 Ford F-350-Super-Duty

All in all everything went together pretty well and I did the install single handed. Couple whacks with a mallet and a few choice %$#@ and a ^%$@!, and it went together exactly as described. Another pair of hands would certainly have helped with the center section but only a bit. Missing one flat and one lock washer- 2 washers away from 5 stars. Can't really complain too much about that so I'm a satisfied customer!

Thank you etrailer



by:

Thanks for all the information on such a big and important purchase. Great photos and even better videos!

At first I looked for a shop to install my hitch, but after watching your videos I decided to go for it myself. If you read the directions carefully and have average wrenching skills the B & W underbed install for gooseneck was pretty straightforward.

It took perhaps 4 hours for me to install. Now I KNOW it was installed correctly and understand the hitch system to a t. Great product. Hooked up to my 15,000 lb fifth wheel and towed with ease using the Companion 5th wheel set up that is designed to be used with the underbed gooseneck.

Everything was delivered on time and in great condition and the quality of the B&W is outstanding. Thank you!

2015 Ford F-250 Super Duty

This is my 2nd B&W underbed 5th wheel/gooseneck kit. Both have installed with reasonable ease, especially considering how many parts under the bed can interfere. No cutting or modifying to fit required. All hardware is provided and everything is heavy duty. This went on a 2015 F250 gas. If I get another truck I will get another B&W kit.



by:
2015 Ford F-250 Super Duty

As always the product came quickly. I bought a B and W gooseneck hitch. My son and I installed it in my 2015 F-250 in about 2 hrs. It was a cake walk. Everything fit together great and extremely easy. Looking forward to using it to pull our horse trailer to go camping. Looks like I'll be buying from etrailer some more. Great products-Great Service. 5-1-20

This item was delivered On time and in great condition...the installation instructions were easy to follow and went in as stated. I was hesitant to saw a 4 in h hole in the bed of the truck thinking it might be off but...it fit exactly where the hole was. Sweet! I just can't say more a out how happy we are with this. This is my second item delivered from etrailer. I got the fifth wheel for the Dodge truck also. Thank you.

Great fit and installation was accomplished with only one person, although a second set of hands would help.

Well made, the instructional video helped tremendously as I am a visual learner. The powder coating job is excellent and the hitch works great with the B&W Companion.

I spoke with Jamie to make sure I ordered the correct 5th wheel hitch for my truck and she went above and beyond. Ordered 11-July (Monday morning) and was delivered 14-July (Wednesday afternoon). I couldn't have asked for a better experience. Haven't installed the hitch yet so only time will tell on that.



by:

The Installation was simple and the video provide step by step instructions. I finished the installation in about four and a half hours in my driveway without the use of a lift. The mount is excellent quality and very sturdy.



by:

The video sent via email with the purchase was 100% exact to my truck and made it really easy to install. I never had to look at the directions because the video showed everything step-by-step. A local truck supply shop was going to charge $700 and said it would take all day. I did it in 4.5 hours with the video and it was the first time installing one of these. Highly impressed overall.

All the parts are clean and well made. The install went well. I really like the under bed mounting instead of the rails in the bed that get in the way.

Products I received were the best quality. The sevice from etrailer.com was of the highest standards from time I ordered on line till the parts were delivered, and after delivery they made sure everything was ok.

2016 Ford F-350 Super Duty

Under bed installation went very well in my 2016 F350. My bed appeared to already come with a dimple mark for the 4 inch hole, but I checked measurements anyway. Good thing I did because the factory mark was 5/8 inch off toward bumper. Other than that, install was a snap. Took my brother and I 100 minutes start to finish.

I love the clean in-bed look!



by:

Great hitch best as far as I am concerned and E trailer also very good to work with always courteous and very helpful

Whole system still working well, no rusting or seizing of components. Only issue I have had was one of the bolts on the exhaust lowering bracket came loose, needs a Nylock nut. Other than that, very happy with purchase.

  • Best 5th Wheel Hitch Setup For Full Bed Access On A 2011 Ford F350
    Hello Jonathan, thanks for reaching out. The best way to keep full bed access on your 2011 F350 will be to go with a B&W Tunoverball/Companion hitch setup. For your truck you can use # BWGNRK1111-5W for the installation kit and the # BWRVK3400-5W Companion 5th Wheel Hitch. There are a few big advantages to going with this setup. First, the installation kit is actually a B&W gooseneck hitch. So, with the hitch removed from the bed, you will still have the full bed at your disposal with...

Instead you will want the B&W Custom Underbed Installation Kit item # BWGNRK1111-5W. This is a comparable below bed system that allows you to have a clear bed when you are not towing. It provides a square gooseneck receiver that allows you to mount the B&W Companion 5th Wheel Trailer Hitch w/ Slider item # BWRVK3400-5W. These two systems combined...

If you do not have it then you would want the part # BWGNRK1111-5W for the hitch/rail kit and then the part # BWRVK3400-5W for the Companion Slider hitch. The slider B and W Companion hitch for the Ford Hitch Prep package is # BWRVK3370.

  • Compatibility of Curt Gooseneck Hitch with B&W Companion 5th Wheel Hitch
    To install a fifth wheel hitch that would be compatible with your existing Curt gooseneck hitch, I'd recommend using Curt X-5 adapter, part # C16210. This adapter will lock into a Curt Double-Lock, Flip and Store gooseneck hitches (C-60 and C-600 series). The adapter provides bed rails for a fifth wheel hitch that uses industry standard bed rails like Reese, Curt, Draw-Tite, Valley or Husky. The Curt Q20, part # C16130 would be a good choice. The hitch has a 20,000 lb capacity and a dual...

There is no adapter product to convert that round gooseneck ball receptacle to a square one that can accept the B&W Companion 5th wheel # BWRVK3500 or the flatbed version # BWRVK3050. If you truck did NOT have the factory rail kit you could install the B&W Fifth Wheel Installation Kit # BWGNRK1111-5W which would then allow you to use the Companion 5th wheel hitch.
