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).

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.

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!

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 ^%[email protected]!, 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

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.

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.

Excellent product and quick delivery.

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.

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

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.

Works perfect. No issues at all.


Comments
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.

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:
2015 Ford F-350 Super Duty

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.
Thank You! for a great online shopping experence




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.

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

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.




by:
2015 Ford F-350 Super Duty

Arrived in less than a week. took me, alone, about 5 hours to install. Instructions were clear and understandable. Certainly well thought out and designed.

I received my product in three days as expected with no issues. I would highly recommend etrailer!

Any suspension kit that also installs on the outside of the frame will not work, but one that installs inboard or on the bottom of the frame should be compatible.

  • Are Safety Chains Required for 5th Wheel Trailers
    5th wheel trailers do not require safety chains the way ball hitches like goosenecks do. Chains are only needed on ball-type couplers like standard receiver hitches and goosenecks. Since a 5th wheel connects at a king pin rather than a ball no chains are needed. Gooseneck hitches like # BWGNRK1111-5W include safety chain loops but 5th wheel hitches do not.

    The trailer you are purchasing is the reason you wouldn't need a slider hitch.

    I looked up your vehicle and was able to come up with two different 5th wheel trailer towing capacities you could have. If you have a 3.73 gear rear end you would have the capacity for a 12,200 lb trailer. If you have the 4.10 gear rear end you would have the capacity for a 15,600 lb trailer. You will be able to determine the gear ratio of the rear end by checking the VIN number plate in the door. For a fifth wheel trailer setup that will work well for you and will give you total bed...

    We have just what you are looking for. The B and W Companion hitches like the part # BWRVK3400-5W are great because they install in a gooseneck hitch ball hole instead of into large rails that would obstruct the bed of your truck when not towing. The part # BWRVK3400-5W is a slider hitch which is what your 2016 Ford F-250 short bed would need to give you the needed clearance to make tight turns. The correct rail kit you would need is the part # BWGNRK1111-5W. What's nice about this route...

  • B and W Companion Fifth Wheel Hitch Setup Recommendation for a 2016 Ford F-250 Short Bed
    For the 2016 Ford F-250 short bed you would be able to get by without having to use a Reese Revolution/Sidewinder. You would just have to use a slider fifth wheel hitch to give you the turning clearance needed. If the truck bed was shorter than 6 feet you would need the Sidewinder but for a 6-3/4 foot bed the slider will work fine. For that you would want the Slider Companion part # BWRVK3400-5W and then the rail kit part # BWGNRK1111-5W.

  • Fifth Wheel Hitch Recommendation for 2012 Ford F-250 Short Bed
    For your 2012 Ford F-250 the B and W fifth wheel setup would be what we recommend. This is the nicest hitch on the market as most would say so we recommend it very highly. Since you have a short bed truck you do have to go with a slider hitch so that you have turning clearance. That means that for a hitch you would need the part # BWRVK3400-5W and then for the rail kit you would need the part # BWGNRK1111-5W. This hitch has a 20k towing capacity so it would be great in that regard as well.

    The B&W Companion # BWRVK3400-5W measures 15" from hitch post to furthest part of the front (or cab-side) of the hitch; so you have 5" of space to work with. The Companion is considered by many to be the single best option for a fifth wheel hitch, and for evidence you can take a look at the over 350 reviews on our site; almost all of which are 5 stars. Since you have the Turnoverball BWGNRK1111-5W already installed in your 2014 Ford F-350, you will not need any other parts to use this...

    Gooseneck trailers are primarily commercially used, while 5th Wheels are primarily used recreationally. Goosenecks come in a variety of styles, some hitch balls are fixed, while others are detachable so you can remove from the bed or change it the ball out to a different size. We even have gooseneck balls that fold down into the bed of the truck, to provide more clearance when the gooseneck is not in use.

    I recommend using the B&W Companion # BWRVK3400-5W and underbed kit # BWGNRK1111-5W because it's got a little bit higher capacity than the other two hitches you mentioned, which is important since you haven't bought a trailer yet, and the B&W Companion has a dual jaw as opposed to the single jaw heads of the others. At the end of the day, a dual jaw head is going to provide you with better contact with the trailer's king pin, which leads to less rattle and better security when towing-it's...
