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 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...

  • 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 Draw-Tite 5th Wheel/Gooseneck Wiring Harness 7-Pole # 20110 to complete the installation. I linked installation videos of these components to walk you through the processes.

  • 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...

  • 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...
