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).

  • What B&W Companion Hitch do You Recommend for My 2021 Chevy Silverado 3500?
    For a B&W Companion hitch that will fit your 2021 Chevy Silverado 3500, I recommend the # BWRVK3400-5W (20K gross towing weight). This hitch has 3 adjustable heights and comes with a built-in slider. With the hitch, you will need the Custom Underbed Installation Kit for B&W Companion 5W Hitch # BWGNRK1019-5W along with the Curt 5th Wheel/Gooseneck Wiring Harness 7-Pole # C56000 to complete the installation. I linked installation videos of these components to walk you through the processes.

  • Is an Under-Bed Mounted 5th Wheel Hitch Option Available for 2021 Chevy Silverado 1500
    By 'standard bed', I assume you're speaking of the 6-1/2 foot bed. If that isn't the case, please let me know. There isn't a puck system available that's like the OEM puck system offered on the 3/4 and 1 ton trucks, but we do offer a solution that might work for you that has the mount for the hitch install so it's under the bed which leaves the bed unobstructed. Once the hitch is removed, there'll just be a single hole in the truck bed which won't interfere with loading or unloading the...

  • Under Bed 5th Wheel Hitch Mounting Option for 2021 Chevy Silverado 1500
    We don't offer a puck system that's similar to the OEM puck system, but we do offer a solution that would allow you to install a 5th wheel hitch in your 2021 Chevy Silverado's 6-1/2 foot bed without having bed rails sitting in the bed when the hitch is removed. You'll first install the B&W Turnover Ball gooseneck hitch, part # BWGNRK1019-5W in the bed of your truck which provides a mounting point for the B&W Companion sliding 5th wheel hitch, part # BWRVK3400-5W. B&W makes an excellent...

  • What Sliding 5th-Wheel Hitch do You Recommend for My 2021 Chevy Silverado 1500 Short Bed?
    For your 2021 Chevy Silverado 1500 with a 6-1/2 foot bed, I strongly recommend using a fifth-wheel hitch with a slider when towing your Grand Design 31MB. This is because with your short bed, you need to make sure that you have enough of a slide to ensure that the front end of the trailer will connect with the rear of your truck's cab. For a great solution, I recommend the B&W Companion # BWRVK3400-5W. The Companion comes with a 12-inch slider that is great for navigating sharp turns with...

  • Gooseneck Hitch for a 2021 GMC Sierra 1500
    To add a gooseneck hitch to your 2021 GMC Sierra 1500 you are going to want the Custom Underbed Installation Kit for B&W Companion 5W Hitch item # BWGNRK1019-5W. The underbed install kit gives you the gooseneck hitch plus the added option for a 5th wheel hitch if you ever need one. Please note this will not fit the carbon bed models. To make towing with a gooseneck easier I recommend adding the Curt 5th Wheel/Gooseneck Custom Wiring Harness item # C53CR. This harness puts a 7-way connector...

  • Recommended Sliding 5th Wheel Hitch For A 2021 GMC Sierra 1500 With Air Springs
    If you have Air Lift branded air springs then you should be good to install the B&W Turnoverball Hitch # BWGNRK1019-5W and use the B&W Companion 5th Wheel Trailer Hitch w/ Slider # BWRVK3400-5W. If you have Firestone air springs you'll have to remove them since they mount in the same location as the brackets for both gooseneck and base rail kits. The B&W Turnoverball hitch will give you the most versatility since you'll be able to tow a gooseneck and 5th wheel trailer and then remove...

  • Is There An Aftermarket Puck System For A 2023 GMC Sierra 1500
    There is not an aftermarket puck system available for a 2023 GMC Sierra 1500 so you would have to switch to the turnoverball hitch style in order to mount a Companion 5th wheel hitch in your truck bed. For this I recommend the Custom Underbed Installation Kit for B&W Companion 5W Hitch # BWGNRK1019-5W. This will allow you to install a sliding Companion 5th Wheel Hitch # BWRVK3400 for fifth wheel towing and also the ability to tow gooseneck trailers.

  • Recommended 5th Wheel and Gooseneck Hitch for 2021 Chevrolet Silverado 1500
    In order to have both a gooseneck and 5th wheel hitch I recommend the Custom Underbed Installation Kit for B&W Companion 5W Hitch # BWGNRK1019-5W. This custom kit will allow you to install a 5th wheel hitch in your truck and doubles as a gooseneck hitch. Once the # BWGNRK1019-5W is installed you will be able to use the B&W Companion 5th Wheel Trailer Hitch w/ Slider # BWRVK3400-5W. This hitch has a built in slider so you can turn safely at slow speeds and will attach to your underbed mounting...

  • Can Underbed Bracket System Fit on 2022 GMC Sierra 1500 6.5 Bed for 5th Wheel Towing
    The underbed rail system we have for your 2022 GMC Sierra 1500 with a 6-1/2' bed is the B&W Gooseneck Hitch # BWGNRK1019-5W which you would then pair with the Companion Sliding 5th Wheel Hitch # BWRVK3400-5W. If you're wanting more of a standard kit then you need the Curt Custom Installation Kit # C65KR but this is an above-bed system. At this time a kit like the Under-Bed Rail Kit # RP30868 doesn't exist for your truck. If you want an above-bed kit then the hitch I recommend is the Curt...

  • Recommended Suspension Enhancement For 2020 Chevy Silverado 1500 Towing Fifth Wheel Trailer
    There are air bags that are compatible with the B&W Turnoverball Underbed Gooseneck Trailer Hitch w/ Custom Installation Kit part # BWGNRK1019-5W and part # BWRVK3500-5W for the 2020 Chevy Silverado 1500!
