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 best of the best. I've used them all. This is a game changer. I can't even begin to explain how much I love this hitch. I used to order all my trucks with the factory puck/gooseneck system. Not anymore. Much cleaner look with the B&W. It's worth the install effort to have a B&W system by far.



by:

I bought a 2020 Silverado 2500, it had a curt gooseneck hitch, it was a pain to remove took like 2 hours to take out, it’s not as well made as the bw hitch glad I put it in, it is well made and easy to install, no problems to install. Thanks for the great product.



by:

Have not installed yet but all the hardware is very heavy duty and painted with no defects looks good



by:

I am happy with the products. I do like the new set up B&W came up with for the newer trucks. One thing I was not happy with was when I ordered the Turnover Ball Hitch along with the Companion 5th wheel hitch for my customer, I was shorted the center section for the Turnover ball hitch. Thankfully my customer was understanding, just put a huge delay in getting it installed and came down to the wire before my customer left for their trip.

2022 Chevrolet Silverado 2500

Had a little hiccup on the delivery, but Tiffany at e trailer took care of everything for me. Got it squared away very very fast. so a big thank you to each trailer for taking care of me.

After having this hitch installed in our truck, we have towed our 5th wheel camper all over the US with no problems.



by:

Very well made, and exceptionally rugged. I had this installed in my 2022 GMC Sierra 2500 HD by a local spring shop that works primarily with heavy commercial trucks, as my truck did not have a 5th Wheel/Gooseneck package. They were very impressed with construction, fit, finish and ease of installation. I also purchased the B&W Companion 5th Wheel hitch to go along with it, to tow my 14k lbs. camper. I have just completed a 1200 mile trip towing camper from Wisconsin to northern New England, and I was very pleased with the performance of both components.



by:

Received this Underbed Installation Kit, the quality of the hardware was perfect! The reason I gave it a 4-star review vs 5-star was the documentation. We had to go to the Website to find the Step-by-Step installation instructions. It would also be VERY helpful if they would BOLD the Hand Tighten Only stuff to ensure this isn't missed. We tightened several of the bolts and found out later these needed to be loosened until final assembly.



by:

Fit is perfect and just as advertised, instructions were complete and very detailed



by:

I purchased this unit because I wanted to keep the bed as clean as possible when not towing. After getting a quote for installation I decided to try it myself. It went very well. Recommend 2 people for installation because it is heavy. Went in with little difficulty. Would recommend highly.



by:

Great hitch
Wouldn’t buy any other brand

Product is excellent and etrailer.com is even better. I wouldn't buy anything but a B&W and every time I do buy etrailer has it here in days. This is my 3rd hitch from them and every time has been flawless. Very happy.

  • Best Underbed Fifth Wheel Rail Kit to Fit 2020 Chevy Silverado 3500
    The best underbed fifth wheel rail kit we have for your 2020 Chevy Silverado 3500 is the B and W kit part # BWGNRK1020-5W. This will leave the smallest foot print in your truck bed when you are not towing as there will only be one hole in the center of the bed and it allows you to install what many consider to be the best fifth wheel hitch available with the B and W Companion Slider part # BWRVK3400 for if you have a short bed or the fixed version part # BWRVK3500 for if you have a long...

  • Can I Still Use My Companion With My New Truck Or Do I Have To Start Over With A New Hitch
    It's really going to depend on what the setup is in your new GMC Sierra 2500. If you have base rails, like part # C16429-204, then your Companion # BWRVK3500 would not be able to adapt to fit the base rails and you would instead need a hitch like the B&W Patriot # BWRVK3255 or # BWRVK3270 if you have a short bed.

    The only 'puck' system that's currently available for the 2020 Chevy 3500 is the factory installed one. This being said, there is an under-bed mounting option that involves using a B&W Gooseneck Hitch for the under-bed hitch mount. For the under-bed portion, you'd use # BWGNRK1020-5W. Then, you'd use the B&W Companion that attaches to the hole where the gooseneck ball would install.

Without the puck system you have the option of going with bed rails, which sit above the bed permanently and will take up space, or using a B&W Turnoverball gooseneck hitch and their Companion hitch. If you want base rails then I recommend the B&W Patriot 5th Wheel Trailer Hitch w/ Slider #...

However, if you want to safely make tight turns and not have to worry about bashing the back of your cab you're going to want the extra clearance a slider provides.

  • Recommended 5th Wheel Trailer Wiring Harness for 2021 Chevy Silverado 2500
    I'd recommend the Hopkins # HM54FR which would provide both a 7-way and a 4 pole trailer connector in the bed of your Silverado. You'll remove the factory knockout or fake plug in the inside wall of the bed, and install the harness as outlined in the video I've linked for you. The # BWGNRK1057 B&W Turnover Ball gooseneck hitch you'd looked at wouldn't be a fit for your 2021 Silverado 2500. You'll want to use the # BWGNRK1020-5W.

Both of these systems are confirmed to fit the 6-3/4' and 8' bed lengths of the 2022 GMC Sierra 2500. The main advantage of the B&W over the Curt is that B&W has 5th wheel hitches made specifically for their turnover ball system. These hitches are some of the best 5th wheel hitches on the market.
