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.



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.

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.

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:

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!!!



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.

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!

  • Can B&W Companion 5th Wheel Hitch be Installed in 2019 Chevy Silverado 3500 With Bedliner
    Yes you can absolutely install the B&W Companion fifth wheel hitch in your 2019 Chevy Silverado 3500 with a bed liner. In terms of doing anything special, if it is a spray-in bed liner you do not need to do anything because a spray-in liner is not thick enough to interfere. If your 2019 Silverado 3500 has a drop-in bed liner you are going to need to remove it or cut it so the entire base of the Companion is making direct contact with your truck bed; if you take a look at the accompanying...

  • 5th Wheel Hitch For 2016 Chevy Silverado 3500 w/ B&W Turnoverball Gooseneck
    While you can use a 5th wheel hitch in your 2016 Chevy Silverado 3500 that has the B&W Turnoverball Gooseneck # BWGNRK1016-5W, you can't add separate rails, with the reason being the gooseneck takes up the spot on the frame where the rails install. What you can do though is add the B&W Companion 5th wheel, which mounts directly in the Turnoverball, and you can use either the fixed hitch (if you have a long bed) or sliding hitch (for a standard/short bed): - B&W Companion 5th Wheel Trailer...

    I would be happy to help you set your truck up with an underbed system but you are going to need to go with B&W's Turn-over-ball. There are no aftermarket puck systems for your 2018 Chevy Silverado 3500. To add the Turn-over-ball system to your Silverado you will need the Custom Underbed Installation Kit for B&W Companion 5th Wheel Trailer Hitches item # BWGNRK1016-5W.

  • 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.

    Thanks for reaching out! For your application I recommend using the B&W Companion # BWRVK3400-5W which mounts to your 2017 GMC Sierra 2500 6-1/2' bed with the B&W Gooseneck Hitch # BWGNRK1016-5W. This design gives you a clear truck bed when you aren't towing, doubles as a gooseneck hitch, and is arguably the best 5th wheel setup for short bed trucks on the market. In addition to this hitch system I also recommend adding the Pollak 5th Wheel / Gooseneck T-Connector # PK11893-11932 so it's...

  • 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...

  • 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...

If it has a standard fixed pin box the slider is the other way to prevent your trailer overhang from suddenly "making friends" with the back of your truck's cab.

Since your truck has a short bed you'd need a slider hitch so that you'd have enough turning clearance to make sharp turns without cab and trailer nose interference.

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.

    As you may already know, any truck bed shorter than 8' requires the use of either a sliding 5th wheel hitch or a Sidewinder king pin box. A sliding 5th wheel hitch is needed for making sharp turns as the trailer can strike the cab of the vehicle if the proper clearance is not made. The slider allows the vehicle to make normal turns during low-speed maneuvering by locking in place between the cab and rear axle. The greater space between the cab and trailer allows for greater turning clearance....

Either way you won't be able to safely tow a 16,000 lb 5th wheel trailer so you'll either need to upgrade your tow vehicle or look into a smaller 5th wheel trailer. Since it sounds like you already have the truck it would obviously be more cost-effective to keep the truck and just look for a smaller trailer....
