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.


Operating Handle

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).

  • Recommended B&W Turnover Ball System for a 2023 Ford F-350 w/out the Prep Package
    The Custom Underbed Installation Kit for B&W Companion 5th Wheel Trailer Hitches item # BW83FR and item # BW73FR are identical kits that both fit the 2023 Ford F-350 with either the 6-3/4' or 8' bed lengths. It looks like item # BW83FR was the original inventory number but they both have the same components, installation method, and capacities. I have previously checked with B&W on this Turnoverball system, since you do not have the prep package you will want the B&W Turnoverball Underbed...

  • Recommended In Bed 7-Way Connector for a 2023 Ford F-350
    To add an in bed 7-way connector to your F-350 you will want the Curt 5th Wheel/Gooseneck Custom Wiring Harness item # C57010. I really like this harness because it puts a 7-way connector in the bed of your truck and allows you to keep the one on your bumper. This makes hooking up to your gooseneck or 5th wheel trailer easier and more convenient. What sets this wiring harness apart from the others is that this kit includes rubber well nuts that separate the included stainless steel bolts...

  • Best Fifth Wheel and Gooseneck Hitch Solution for 2024 Ford F-350 without OEM Pucks
    Hey Miguel, this is a great question but I think your first though of going with the B and W setup is the best. So for that you'd want the part # BWRVK3500 for the fifth wheel hitch and then for the rail kit that also doubles as a gooseneck hitch you'd want the part # BW83FR which also doubles as a gooseneck hitch. This gives you exactly what you are looking for. Ability to tow a fifth wheel hitch, a gooseneck hitch, and then when not needed a totally clean truck bed. The Companion hitches...

  • Is A Sliding 5th Wheel Hitch Required When Towing With A 6' Bed
    Typically with any bed under 8' in length we recommend using either a slider hitch or fixed hitch and rotating pin box to prevent the nose of the trailer from coming into contact with the cab of the truck when making tight turns. There are some trailers that have tapered noses that allow for more turning clearance, but it's always best to play it safe. You can see how much turning clearance you have by taping a plumb bob to the outermost corner of the trailer's nose and measuring from...

  • Is There a 5th Wheel Hitch & Underbed Rails For 2023 Ford F-350 Long Bed
    Hi Joe, While there is an option for an underbed kit and a 5th wheel hitch for your 2023 Ford F-350 long bed, there isn't a prep package-style that fits your truck. So for a long bed, what you would need is the B&W Companion 5th Wheel Trailer Hitch # BWRVK3500-5W and Custom Underbed Installation Kit # BW83FR. The # BW83FR also doubles as a gooseneck if you ever want to pull a gooseneck trailer or use something like a Reese Goose Box, and the Companion is simply the best 5th wheel hitch...

  • Gooseneck and 5th Wheel Hitch for 2023 Ford F-350 Dually Long Bed Without Prep Package
    The B&W Custom Underbed Installation Kit # BW83FR you were looking at is the correct gooseneck hitch for your 2023 Ford F-350 dually. It has a custom installation that uses the existing holes in your vehicle's frame so no welding or drilling is required. This is a gooseneck hitch as well as a base which will allow you to install the B&W Companion # BWRVK3500-5W.

  • What 5TH Wheel Hitches Will Fit B&W Turnover Gooseneck Hitch # BW83FR?
    The Custom Underbed Installation Kit # BW83FR is only capable of using the B&W Companion Fixed # BWRVK3500 or Sliding # BWRVK3400 hitch. You can use an Adapter # DM6140 to work with other 5th wheel hitches which fit onto standard ISR rails. Since you have the in bed prep/puck system on your 2023 Ford F-250 short bed truck I recommend using the Companion # BWRVK3370 since you cannot install the B&W under bed kit above.

  • Recommended 5th Wheel and Gooseneck Hitch for a 2023 Ford F-250 Super Duty
    Hey Dan, so we do have the Andersen Ultimate # AM3200 but it's mounts to a set of 5th wheel rails # RP65VR to provide you with a Gooseneck attachment. I'm not entirely sure if that's what you're looking for but that's what it is. There is also the Custom Underbed Installation Kit for B&W Companion 5th Wheel Trailer Hitches # BW83FR which is a Gooseneck hitch that can be also used with the B&W Companion # BWRVK3400-5W 5th wheel hitch. Both of these will work with a 6 3/4' bed. Also,...

  • Will The Reese Elite Underbed Rail Kit Fit A 2023 Ford F-350 Super Duty
    The Under-Bed Rail and Installation Kit for Reese Elite Series 5th Wheel Trailer Hitches # RP87FR has not yet been confirmed to fit the 2023 model year of the F-350. You could try reaching out to Ford to see if there are any differences compared to the 2022 models, which the # RP87FR is confirmed to fit, to see if it would fit your 2023. If it will not fit then you could install the Custom Underbed Installation Kit for B&W Companion 5th Wheel Trailer Hitches # BW83FR and swap the base...

  • Can I Add a Aftermarket Puck System to a 2023 Ford F-250?
    I am sorry but there is no way to add a puck system to a 2023 Ford F-250 using aftermarket parts. The puck systems are dealer options only. The closet thing you can do would be to add the B&W Turnoverball system item # BW83FR to your F-250. The Turnoverball system installs below your truck bed using custom brackets. It provides a square receiver capable of mounting a Fixed Companion 5th Wheel Hitch item # BWRVK3500 or a Sliding Companion 5th Wheel Hitch item # BWRVK3400-5W. One part of...
