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

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!

As advertised

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:

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.



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:
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-250 Super Duty

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

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.

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.

  • 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.

  • Firestone Air Bag Suspension Enhancement Recommendation for 2013 Ford F-250 w B&W Hitch
    Yes, the Firestone air bag kits will fit your 2013 Ford F-250 that has a B and W hitch setup installed. If you have a diesel engine you would want the part # F2597. If you have a gasoline engine you would need the part # F2550. I attached install videos for these for you to check out as well.

  • How to Determine if 2012 Ford F250 6 3/4 ft bed Has Rail Kit for Picking Out Fifth Wheel Hitch
    Look in the bed of your 2012 Ford F-250. Do you see 4 holes cut in the bed around the center of it? If so then you have the factory rail kit. If not then you do not have it. 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.

  • Max 5th Wheel Trailer Weight Ratings for a 2015 Ford F-250 XLT Crew Cab 6.2L V8
    According to my research your 2015 Ford F-250 Crew Cab should have a GCWR of 19,200 lbs (this will be located on a sticker in your door jamb) which means that if you have a 4x2 your max 5th wheel towing capacity is 12,400 lbs but if it is the 4x4 your max 5th wheel towing capacity is 12,100 lbs. Ford states that the tongue weight should be within 15-25% of the weight of the loaded trailer for 5th wheel towing which puts your range at 1,860 lbs - 3,100 lbs (for the 12,400 lbs) or 1,815 lbs...

    For your 2015 Ford F-350 with the 6 foot bed, I would look at a slider 5th wheel hitch to allow yourself enough clearance when making 90 degree turns wth the shortbed design of your truck. The B&W Companion 5th Wheel Hitch # BWRVK3400-5W and the B&W Custom Under-bed Installation Kit # BWGNRK1111-5W is the 5th wheel hitch that I recommend for your application.

    When using a product like the Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter # RP85FR, it can be used with a short bed truck but it won't give you any additional turning clearance. If the 5th wheel trailer is really narrow or has a tapered front cap that was designed to be towed by a short bed truck then you would be fine.
