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).

Awesome hitch!! Awesome service and communication from etrailer . Very helpful videos of installing your products. I highly recommend buying from etrailer. In stock with timely shipping. I received my hitch in two days.

Awesome product. Extremely heavy duty construction and expertly designed.



by:

Highly recommend watching etrailer video prior to installing. I dry fitted most items prior to permanently placing and bolting. The bracket wasn't easy but you could defiantly get it done yourself. Everything was built with good quality and beefy where you need it. The latch good be done a little smoother but operates like most fifth wheel releases.



by:

B&W gooseneck hitch and fifth wheel combo was of good quality. Very heavy components but with help, install wasn’t bad. Only 4 stars because it arrived with a considerable amount of cosmetic damage. Parts were banging around in less than adequate packaging. Some filing was necessary on a few mating pieces. Ordering and ship time was excellent. etrailer is the best.

2022 Ford F-350 Super Duty

The box came taped together and falling apart the parts had no protection from each other. The powder coat is scratched, marred and chipped now I have to prime and paint all the parts before I install them. B&W needs to package there stuff better. I planned to paint the parts for an extra layer of protection as I live in the north east. Now that the powder is chipped I have to do a professional paint job too make this hitch last. Unfortunately B&W is still the best hitch for my application so I’ll buy another one again but I don’t like having to spend a day prepping parts and painting after I paid a premium price for what was supposed to be a premium product.

2020 Ford F-250 Super Duty

Mu teenage son and I (I have a bad back so not moving to well at the moment) installed the BW underbid kit on 2020 Ford F250 4x4, FX4 SRW, Crew Cab with no issues. We followed instructions and watched video and pretty easy install. On my truck there is No heat shield near spare tire to remove prior to install and we did not remove the exhaust nuts to lower pipes and had no issue getting all brackets installed. We did it on driveway with truck rear tires on truck ramps. Took about 5 hours from start to finish with some breaks in between. I just placed two 8' 2x4's across bed of truck when you get to part using a ratchet strap to lift into 4" hole in bed tightly. works great. High high quality parts........Thx etrailer



by:

Works like a champ. Install was a lot of work and the rear section will block the bolt to remove the right rear shock so make sure you either cut a notch out or plan on keeping your shocks. Torquing to spec gets very tricky with several of the bolts but can be done with a little patience. Operation is very smooth and the hitch itself is bombproof



by:

The installation took about 6 hours and I took my time, the only thing I would recommend is checking the threaded holes for weld splatter maybe running a thread chaser in them , I had just one hole that had to be cleaned up and would have been easier on the bench . Other than that everything fit perfect.

by:
Ford F-350 Super Duty

Works well. Tough install. Best to have another set of hands. Better still if you can do it on a lift. Dont know if all vehicles present same challenges to the install as our F-350 diesel long bed. Most forward outboard drivers side bolt hard to get in or torque. Pretty straightforward though. Took me a couple of hours one day and finished up couple of hours next day. Could have opted for the Ford factory kit, but it required removing the bed and the accompanying labor cost.

  • Recommended 25K 5th Wheel Hitch For A 2022 Ford F-350 DRW
    Typically you'll only want to use 80-85% of any item's total capacity to keep a buffer safety zone so that you never risk having a product fail. You're correct that the only Companions at 25k capacity are for OEM puck systems. B&W is a great brand and is my favorite as well, but in this case they're not going to have anything compatible with with the # BWGNRK1116-5W that's going to have over 20k capacity, so you'll have to look at another brand.

  • Recommendation for Best Fifth Wheel Hitch for 2019 Ford F350 RWD Long Bed
    The exact hitch needed will depend on whether your 2019 Ford F350 has the factory tow prep package with the pucks in the bed or not. When it comes to trouble-free performance, durability and ease of use, you can't go wrong with B&W 5th wheel hitches. When somebody asks for the best, that's where we point them. The B&W Companion offers massive 1 inch thick jaws that contact the king pin all the way around for a smooth rattle free ride. Not having full contact causes the jerking and banging...

  • Recommended Fifth Wheel and Gooseneck Hitches for 2017 Ford F-350 Without Factory Rails
    You just described the perfect situation for someone to have a B&W Companion Fifth Wheel Trailer Hitch # BWRVK3500-5W. The Companion fits directly into B&W Custom Underbed Installation Kit # BWGNRK1116-5W which doubles as a Gooseneck hitch. Both are confirmed to fit your 2017 Ford F-350 that has a long bed. Since the fifth wheel installs into the gooseneck there are no rails left in your bed giving you full access when not towing. The gooseneck ball turns over inside the hitch tucking...

    Yes, the B&W Companion OEM 5th Wheel Trailer Hitch w Slider # BWRVK3370 has a sliding base and hitch head to couple to your 5th wheel trailer. This specific model is designed to attach to Ford's in-bed puck system so you would need to have that in your 2019 Ford F-350 in order to use this hitch. If you don't have a puck system then you'll need to use the B&W Companion 5th Wheel Trailer Hitch w/ Slider # BWRVK3400-5W along with their Custom Underbed Installation Kit # BWGNRK1116-5W. This...

  • Recommended B&W Gooseneck and 5th Wheel Hitch for 2017 Ford F-350
    For your 2017 Ford F-350, the B&W Companion # BWRVK3500-5W is one of the most popular 5th wheel hitch options. It is extremely well made in the USA and is designed to work with the Custom Underbed Installation Kit for B&W Companion 5th Wheel Trailer Hitches # BWGNRK1116-5W so you get that clean bed when not in use. The underbed gooseneck hitch will add 137 lbs to your truck and then when you add the 5th wheel hitch it will be an additional 205 lbs. If you have a short bed truck you...

  • Is There a Sidewinder for Rhino Pin Box Using 2022 Ford F-350
    I do have an option for you but there isn't a rotating pin box replacement for the Lippert Rhino. That said, you can still make full turns without this but you would need a sliding fifth wheel hitch like the B&W Companion OEM 5th Wheel Trailer Hitch part # BWRVK3370 which is a fit for a 2022 Ford F-350 with Prep Package. If you don't have the Prep Package then you will need to use the B&W Companion 5th Wheel Trailer Hitch part # BWRVK3400-5W with part # BWGNRK1116-5W.

  • How Difficult Is Installation of Reese RP87FR Elite Under Bed Rail Kit on 2017 Ford F-250
    The Reese Elite Series under bed puck system, part # RP87FR is compatible with your 2017 Ford F250. The puck spacing is identical to hat of the Ford OEM system, so you'd be able to use any puck mounted hitch designed for the Ford OEM tow/prep package puck system. As you can see by clicking the provided instruction link, the bed will indeed need to be removed temporarily for the installation of the rail kit.

  • Underbed Fifth Wheel/Gooseneck Hitch Recommendation for 2018 Ford F-250 Short Bed
    We can help you with selecting an underbed fifth wheel/gooseneck kit for your 2018 Ford F-250 short bed but the only place to get the factory in-bed rail kit is through Ford. Reese use to sell it aftermarket but now it's only available through Ford.

  • Recommended Solution for Clean Truck Bed When Not Towing 5th Wheel on 2020 Ford F-250
    I have a solution for you, but the Andersen Ultimate # AM3200 is not compatible with a Reese # RP30126; the Reese system is not a fit for a 2020 Ford F-250 and the Andersen Ultimate requires standard base rails so it doesn't sound like this would be the best combination for you.

  • Choosing Between the Demco Autoslide and B&W Companion for 2020 Ford F-250 without OEM Prep Package
    I can understand why a hitch like the Demco Hijacker Autoslide # DM8550022 (18k) or # DM8550037 (21k) is so attractive; they provide a much better solution for towing a 5th wheel with a short bed truck when it comes to not having to get in and out of the truck each time you need to make a tight turn. With that said, they're not compatible with B&W Turnoverball Underbed kits like the # BWGNRK1116-5W since the hitches connect to the underbed kit in two very different ways. In order to use...

You might also be interested in an onboard compressor system like # F2219, which would allow you to add or remove pressure from the system, as your load and road conditions vary. This is a very convenient option, you'll never need to mess with a plug-in compressor or need to find a gas station to add air to the system. I've linked to...

  • Differences Between Above and Under Bed Fifth Wheel Hitch Mounts for 2020 Ford F350
    There are two ways to install a fifth wheel hitch on a pick up truck. One would be to use standard bed-mounted rails. Brackets are mounted to the truck frame with the bed rails sitting directly above. Holes are drilled down through the truck bed to correspond with holes in the brackets bolted to the frame, allowing the bed rails to be securely bolted down. The rails have slots in them that allow the hitch to be installed and removed pretty conveniently. The problem here is that once the...

    For your 2020 Ford F-350 Super Duty Long Bed (8 foot) we have several options of fifth wheel trailer hitches. My favorite is the B & W fifth wheel hitch. They have a really nice finish to them that looks good in any truck, and the powder coat is very durable, so it resists scratches pretty well. The biggest reason for me favoring B & W hitches is the ease of install, out of every fifth wheel I have installed, B & W seems to be the most straight forward and install the smoothest. Which...
