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.

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:

Easy to order and fast on delivery. Definitely heavy duty!



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

by:

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.



by:

Great product! Great website! Installing this fifth wheel kit was not for the faint of heart but with installation videos and clear, easy to understand instructions. We got ‘er done! Shipment came 3 days earlier than expected

  • Best 5th Wheel Hitch for 2020 Chevy Silverado Short Bed without Factory Prep Package
    The best 5th wheel hitch available for the new 2020 Chevy Silverado 2500HD with the 6.9 foot bed and without the factory prep package is the B&W Companion Slider # BWRVK3400-5W along with the Installation Kit # BWGNRK1020-5W. The B&W Companion line of hitches are considered by many to be the absolute best on the market. This is in large part due to its heavy-duty construction that includes 1 inch thick dual jaws that provide an incredibly secure connection to the trailer that not only...

  • Recommended Underbed 5th Wheel Towing Kit for 2021 GMC Sierra 2500 Short Bed without OEM Pucks
    I may have a solution for you, but there are currently no OEM style prep package kits available for your 2021 GMC Sierra 2500. Since you would likely need a hitch that has legs designed for the newer GMC prep package anyways, if you don't already own one, you might want to consider the B&W Turnoverball System # BWGNRK1020-5W. The Turnoverball system will give you the same clean truck bed that you would get with the GMC OEM prep package. The hitch you would need to work with the Turnoverball...

  • Recommended Underbed Gooseneck and 5th Wheel Hitch System for 2020 Chevy Silverado 3500 Short Bed
    The factory puck system is not a standard feature that is included on trucks, and would be an option that is added on to certain trucks. If your truck does not have the pucks in the bed, then it's not going to have the components needed available. The good news is that there are underbed mounting systems that will give you the same clear truck bed as the puck system would. You can add an underbed system like the B&W Turnoverball # BWGNRK1020-5W that will put a gooseneck hitch in your...

  • Are B and W Turnoverball Gooseneck Part # BWGNRK1020 and # BWGNRK1020-5W the Same
    The part numbers # BWGNRK1020 and # BWGNRK1020-5W are the exact same Turnoverball gooseneck hitch. We have two part numbers for it though as it shows up in two parts of vehicle fitguides as it works as a gooseneck hitch by itself or as the base rails for a Companion fifth wheel hitch. Our pricing sometimes fluctuates based on how certain part numbers are selling. Best solution I can recommend is go with the one that costs less!

    For a great 5th-wheel hitch and drill-free brackets on your 2022 Chevy Silverado 2500 with an 8-foot bed without OEM prep, I recommend the B&W Companion # BWRVK3500-5W along with the Custom Underbed Installation Kit # BWGNRK1020-5W. 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...

  • Recommended 5th Wheel Rail Kit That Leaves Clean Bed When Hitch Is Not Installed
    I have a solution for you, but installing and then removing the bed rails after each use is going to cause undue stress on the hardware components on the bed rails; these components are designed to be installed once and discarded after installation, so there isn't going to be a rail kit that can be used in this manner. For this reason, I can't recommend using a kit with above bed rails like the B&W # BWRVK2505, which provides industry standard 5th wheel rails to mount a hitch in and instead...

    You will not need a sliding hitch like the B&W Companion # BWRVK3770 you currently have. A sliding hitch is needed on a short bed truck because of the positioning of where the hitch will be mounted, in relation to the cab of your truck and it being too close to each other. The slider would slide back when you make tight turns while towing your 5th wheel trailer, that way there will be no impact to your truck cab.
