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).

Installed this unit myself and worked perfect. Everything was clearly provided in the directions. If you follow the directions exactly everything goes in perfectly smooth. Like the setup allowing use of my bed if needed. I also got the 5th wheel unit and both the 5th wheel and gooseneck are great options.



by:

Install is possible for one person, much easier with two. It can be done on the ground without removing the spare tire. It took me a little over 3 hours to do alone.



by:

Installation was straightforward. Instructions are very clear and concise. Shipping was prompt and I was able to get updates as needed.

2018 Chevrolet Silverado

Nice looking setup. Took me 6 hours to install the gooseneck, and 5th wheel by myself with no lifting equipment in my 2018 Silverado 3500. Everything lined up nice. It was a bit heavy, but I like a challenge. Suggest not to over compensate for the spray-in bed liner, I wish I would not have added any extra to the dimension given in the install instructions. Haven’t had a chance to try it out yet, as my RV trailer is still at the dealership until spring.



by:

B&W is the standard bearer of the 5th wheel hitch industry. You can tell It is very well made. It gives me confidence when towing. etrailer made the purchase easy and is my one stop towing equipment provider.



by:
2016 Chevrolet Silverado 2500

Fantastic service - placed the order last Friday and received my B&W goose neck hitch and wiring harness the following Tuesday. As soon as I get it installed I will be ordering the B&W companion fifth wheel hitch to go with it.



by:

Very heavy duty! Built super well directions are easy as can be... I bought this with the companion slider and it is such a tight fit, no wiggle at all



by:

Good solid hitch, pretty easy install by myself took about three hours.



by:

The directions and video were spot on. The B&W is a lot nicer than any other hitch I have ever owned. Very solid and USA made.



by:

Very happy with installation instructions, help from factory installers, and the overall fit of the under-bed hardware.



by:

Great help over the phone in what would work best for our needs.
But things shipped much later than I was told at the start. I did over the 4 day delivery and the free was waged but it took about 2 weeks to receive. That is why you only got 4 stars!!!

William, I see you had a 2 star experience with the B&W Companion. The Companion is one of our most popular fifth wheel set ups so I am surprised. If you would like to tell me what went wrong, I am happy to help you.

Very well made hitch. Can't wait to try it out. Everything came quickly with no issues. Great price. Why go anywhere else? Thanks!

  • Installing A B&W Companion 5th Wheel Hitch In A B&W Underbed Gooseneck Hitch
    The B&W Companion # BWRVK3500-5W is super easy to install into a B&W Gooseneck Hitch # BWGNRK1016-5W. You'll just need to pull back the locking handle on the hitch and remove the ball. Then simply drop in the # BWRVK3500-5W, which has a post that will fit down into the gooseneck hitch, and pushing the locking handle into the locked position and you'll be ready to couple your 5th wheel trailer to tow.

  • Will the B&W Companion From a 2016 Chevrolet Silverado 2500 Fit a 2020-2022 Silverado 3500
    The answer to your question will depend on which B&W Companion you have and whether or not you have the OEM prep package right now or not. I also don't know which bed size you have but I will assume it will remain the same between the old and new trucks since the short bed needs the slider and the long bed needs the fixed hitch. If you currently have the OEM prep package on your 2016 Chevrolet Silverado 2500 then you will be able to use the head for the hitch for a 2020-2022 Silverado...

    Your B&W Companion 5th Wheel Trailer Hitch - Dual Jaw - 20,000 lbs, # BWRVK3500-5W, will fit both your 2013 F-250 and your 2016 GMC Sierra 2500, but your underbed gooseneck hitch will not. The 2016 GMC Sierra 2500 Denali will require the Custom Underbed Installation Kit for B&W Companion 5th Wheel Trailer Hitches, # BWGNRK1016-5W, to work with your Companion 5th Wheel Hitch.

  • 5th Wheel Trailer Hitch Recommendations for a 2016 Chevy Silverado 3500 Short Bed
    On the short bed trucks like your 2016 Chevy Silverado 3500 I recommend 2 things: an underbed mount hitch and the slider with the most travel you can get. For that I have just the thing; the Companion # BWRVK3400-5W. This hitch is rated for 20K and can travel 12 inches for more clearance. And for an installation kit use # BWGNRK1016-5W. The great thing about this kit is that it is also a gooseneck hitch should the need ever arise. When the hitch is removed the bed will be free of any...

  • Best Way to Upgrade From a B&W Patriot 18k Hitch to a 25k 5th Wheel Hitch in a 2018 Chevy w/o Prep
    Yes, you would need to replace both the head and the base. The Replacement Head Assembly for B&W Companion 5th Wheel Trailer Hitches # BWRVC3006 fits the B&W Companion base. The 18k from B&W is the Patriot not a Companion, therefore the # BWRVC3006 would not fit on the Patriot base. The best and easiest way to increase your 5th wheel hitch to 25k would be to use the Curt A25 5th Wheel Trailer Hitch # C16180 which will attach directly to your industry standard base rails.

    There are underbed 5th wheel/gooseneck install kits for the 2018 GMC Sierra 2500 though they are not exactly the same as the factory one which is made by Curt. You can use B&W hitch # BWGNRK1016-5W and then add the Companion Slider # BWRVK3400-5W for a short bed or the regular Companion # BWRVK3500-5W for long bed models.

  • Can Reese Sidewinder RP34FR be Used w/ 2017 GMC Sierra 2500 w/ B&W Turnoverball in Bed
    We have a number of options for you to pull your 5th wheel trailer with your 2017 GMC Sierra 2500 short bed, though there isn't a 5th wheel hitch you can use with the B&W Turnoverball # BWGNRK1016-5W and a Sidewinder. The reason for that is the B&W Companion that fits in the Turnoverball isn't compatible with the Sidewinder, so the only hitch you can add to this is the B&W Companion 5th Wheel Trailer Hitch with Slider # BWRVK3400-5W. If you did want to use the Sidewinder you still could,...

The adapter rails # BWGNRK1016-5W you had to use with your Sierra 2500 will not be used on your Silverado 2500.

  • Can I Use the B&W Companion 5th-Wheel Hitch on My 2018 Chevy Silverado 3500?
    Typically, 2018 Chevy 3500s come with OEM prep. However, to make sure, there are a few ways to determine whether you have the OEM prep system. The first way is to remove the goose hitch and look for bolt entry points in your truck's bed. This is a dead giveaway. On the video I attached to this answer, it shows the bolt pattern of OEM prep at timestamp 5:22. Also, the existence of a 5th-wheel trailer wiring opening on the inside of the bed is also an indicator. If you determine that you...

    I took a look at the online version of the owner's manual for your 2016 GMC Sierra 2500 and it looks like the max tongue weight for a 5th wheel trailer is 3,000 lbs and the max Gross Vehicle Weight Rating (GVWR) is 21,000 lbs. With this being the case you can safely tow your Keystone Montana 3221RL but I recommend checking your copy of the owner's manual to verify these weight ratings.

  • Removable Fifth Wheel Hitch Recommendation for 2019 Chevy Silverado 2500 Short Bed
    For your 2019 Chevy Silverado 2500 short bed the best solution for a fifth wheel hitch you could easily remove and have a totally empty truck bed would be with a B and W Companion slider like the part # BWRVK3400-5W and then for the rail kit part # BWGNRK1016-5W. Unlike other options that fit your truck bed this would not require a set of fifth wheel rails in the bed of your truck as it installs into a gooseneck hitch ball shank.

I've attached a video where Conner shows the pucks and how to connect this hitch to them. You should also have an in-bed 7-way connection if you have the prep package. If you find that you don't...

The benefit of the under bed mounting system is that you will have full truck bed access with the hitch removed.
