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:

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.

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

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.



by:

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
easy install
It’s versatile to use gooseneck or put in 5 th wheel hitch



by:
2020 Chevrolet Silverado 2500

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.

  • Recommended 5th Wheel Hitch for 2021 GMC Sierra 3500
    The 5th wheel hitch I recommend most often is the B&W Companion. The hitch uses massive 1 inch thick jaws which hold the 5th wheel king pin very tightly which reduces the banging and rattling from road shock experienced by the 5th wheel. B&W hitches are proudly manufactured in the US, and are protected by a lifetime warranty. The exact hitch you'll need will depend on how your truck is equipped and its bed length. Generally speaking, for a short bed truck you'll need a sliding hitch, unless...

  • Is There An Aftermarket Puck System For A 2021 Chevy Silverado 3500 Dually
    There isn't currently an aftermarket puck system available for a 2021 Chevy Silverado 3500 so you would be limited to installing above-bed base rails or a B&W gooseneck hitch and using a Companion 5th wheel hitch for an underbed option. For base rails I recommend the B&W Custom Installation Kit w/ Base Rails # BWRVK2505. This kit includes custom-fit brackets to minimize drilling into the frame of your Silverado and will decrease the installation time. If you were wanting an underbed...

  • 5th Wheel Hitch With Under Bed Mounts for 2022 Chevy Silverado 2500 Short Bed
    We've got a few under-bed rail mounted options available that wouldn't require the bed rails sitting in the truck bed. If you don't mind a manually sliding hitch, the 20K capacity B&W Companion 5th wheel hitch, part # BWRVK3400-5W would be an outstanding choice. The hitch uses 1 inch thick jaws and a dampened hitch head, both of which help minimize the rattling and banging felt in the passenger cab of the truck. The hitch would mount using the B&W Turnover Ball Gooseneck Hitch, part #...

  • Recommended Fifth Wheel Hitch for 2020 GMC Sierra 3500 Long Bed
    The B&W Companion Fifth Wheel Hitch is our most often recommended fifth wheel hitch because of how well it's constructed, how durable it is and because of the superior ride quality offered by the super-bombproof jaw system the hitch uses. The majority of complaints we receive about 5th wheel hitches are about the banging and shaking that occurs when the tow vehicle accelerates or brakes. This is caused by a poor fit between the 5th wheel's king pin and the hitch jaws. The Companion uses...

In 2020 Chevy made some big changes to their trucks so the fits of rail kits had to be upgraded.

We do have options for both fifth wheel and gooseneck mounts, but nothing quite like the OEM puck system. Our most similar option is the B&W Turnoverball # BWGNRK1020-5W and Companion Fifth Wheel Hitch # BWRVK3500-5W. The companion hitch mounts into the receptacle for the gooseneck ball.

  • Recommended Underbed Hitch For A 2022 Chevy Silverado 2500
    To get an under-bed puck system you would need to take your new 2022 Chevy Silverado 2500 back to GM and have them install the system, which can be quite costly and time consuming and there isn't really a guarantee that they will actually install it for you. Another option that would be more cost effective would be to install a B&W Underbed hitch like the # BWGNRK1020-5W. This would give you a clear bed when not towing and allow you to tow both a 5th wheel and gooseneck trailer. To...

  • Comparing the B&W and Curt Underbed Systems for a 2022 GMC Sierra 2500
    I would be happy to compare the B&W Turnoverball System item # BWGNRK1020-5W to the Curt Underbed System item # C60642. 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. If you have a short bed and need a slider item # BWRVK3400-5W or the standard...

The Companion comes with dual-jaws that have a more secure connection and a quieter functionality than sliding jaws. Also, the Companion comes with three height settings to make the trailer more level. It is also 100% made in the U.S.A. As far as the installation...
