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 3-1/2" 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).

by:
2015 Dodge Ram Pickup

Installation in 4 hours might be realistic for a shop, but my old tired bones required a bit more time. Everything lined up and fit my 2015 Ram 2500. The quality of the components are far superior to anything Chinese.

I suggest air tools if you have them, and something to lift the 5th Wheel base into your truck bed unless you feel like a baddass today.

I didn't run into any problems because I read the instructions BEFORE I started. Everything I needed to know was right there!



by:

Received the hitch yesterday, earlier than expected. The packaging was in excellent condition and the parts were fine. The best part is it’s American made. Thanks etrailer.



by:

Very fast delivery. Excellent product, would have given 5 stars except for the paint or power coat quality was poor along all narrow edges. Really appreciated the installation video.
Overall good experience.

Product continues to work well. Used frequently in the last year.

great hitch, smooth installation. took awhile to get the bolts to thread into the L brackets, other than that moving the muffler was the worst part. 2018 RAM

  • Adapter Available for B and W Turnoverball Hitch That Provides Fifth Wheel Rails
    If you installed a B and W Tunoverball gooseneck hitch part # BWGNRK1384-5W in the bed of your 2016 Ram 2500 you have the option of using the Curt X5 Adapter part # 16310 which would then give you a set of industry standard fifth wheel rails. Or, you could use the Companion Slider Hitch part # BWRVK3400 which is designed to fit the Turnoverball.

  • Recommended 5th Wheel Hitch for 2018 Ram 2500 without OEM Prep Package and 6-1/2 Foot Bed
    There are a lot of great options available for your 2018 Ram 2500, but I recommend using the B&W # BWRVK3400-5W and the underbed mounting kit # BWGNRK1384-5W, which has a 20,000-lbs capacity. The # BWRVK3400-5W is a sliding hitch that will install into a gooseneck hitch # BWGNRK1384-5W to give you a truck bed that is free of rails, so it will allow you to freely use your truck bed when the hitch is not being used. B&W make some of the most reliable and high quality hitches on the market,...

  • Is Sliding Fifth Wheel Hitch Needed for 2018 Ram 2500 with 6-1/2 foot Bed Towing 2018 Cougar 310RLS
    The 2018 Cougar 310RLS has a tapered nose with Max Turn Technology so a sliding hitch will likely not be necessary; you still need to be careful and watch the cab before making sharp turns, but this trailer is designed in a manner that you can use a fixed hitch. For your 2018 Ram 2500 with the factory prep package I strongly recommend the B&W Companion # BWRVK3600 because it is considered by many to be the highest-quality fifth wheel hitch available. If your '18 Ram 2500 does NOT have...

  • Will Curt X5 Adapter Fit a 2015 Ram 2500 Short Bed with B&W Turnover Ball Gooseneck Trailer Hitch
    I have a better solution for you because the X5 adapter # 16310 cannot be properly secured in a 2015 Ram 2500 that has the B&W Turnover Ball gooseneck trailer hitch. What you can do is install the gooseneck hitch, # BWGNRK1384-5W, and then use the Companion hitch # BWRVK3500-5W. This set up only works if the truck has rear coil spring suspension. I have linked videos on both parts for you.

  • Best Pin Box for Use with B&W Companion 5th Wheel Trailer Hitch
    The absolute best pin box to use with the B&W Companion 5th Wheel Trailer Hitch part # BWRVK3400-5W and the Custom Underbed Installation Kit part # BWGNRK1384-5W on your 2017 Ram 2500 is the Trailair Flex Air 5th Wheel Pin Box. The Trailair Flex Air pin box has both a cushioned airbag and shock absorber. The airbag is going to act as a buffer between the trailer and 5th wheel hitch. As the airbag absorbs the shock, the shock absorber then prevents any bouncing. This unit also has a pivoting...

  • 5th Wheel Hitch For 2014 Ram 2500 Short Bed With Lift & Large Tires
    It sounds like you want a specific "yes" or "no" for if your 2014 Ram 2500 short bed with a lift and large tires can tow a 5th wheel trailer, and it isn't quite that simple. Can you? Yes. Will it be difficult to be totally level? Yes it will. But it depends on the trailer and there isn't a set number for a height that is a cut-off point for if you can or cannot tow. The only thing I can offer is how to optimize for getting as level as possible, and that starts with the hitch. You'll have...

    The factory puck system that was available for your 2017 Ram 2500 is integrated into the frame and cannot be installed as an aftermarket part. There are some underbed mounted fifth wheel hitch install kits but as of right now none of them install a puck system. The only underbed kit available for your Ram is the B&W, part # BWGNRK1384-5W, that uses the B&W companion hitch, part # BWRVK3400-5W.

  • What Kind of Rails are Needed to Tow a 5th Wheel Trailer with a 2018 Ram 2500 Short Bed
    If your 2018 Ram 2500 short bed has the puck system then yes, you would need a rail adapter like the Demco # DM6099 to use the Andersen Ultimate Connection # AM3200. The Anderson Aluminum 3220 that you referenced does connect directly to a gooseneck hitch ball like part # BWGNXA2062 which negates the use of a rail adapter kit. The downside to the Anderson Aluminum is that even though they advertise a 9" offset it isn't a true offset because it only moves the pivot point back a few inches...

  • B and W Goose Neck and 5th Wheel Towing Solution for 2014 Ram 2500
    For instances like yours where both goose neck and 5th wheel trailers will be pulled by the same tow vehicle, your new 2014 Ram 2500 will benefit from use of a B&W system that can handle both, such as the Companion Slider Goose-neck-to-5th-Wheel Trailer Hitch Adapter # BWRVK3400. This kit works on trucks with coil springs. This item is the 5th wheel portion of the system and consists of the 18K-rated hitch on a slider base.

  • Is There an Aftermarket 5th Wheel Prep System For a 2016 Ram 2500 with 8' Bed
    I do have an option for you, but there is not an aftermarket "puck" system. Instead, you can use the Custom Underbed Installation Kit for B&W Companion 5th Wheel Trailer Hitches # BWGNRK1384-5W. This will have an underbed installation and allow you to use the B&W Companion 5th Wheel Trailer Hitch # BWRVK3500-5W. The Custom Underbed Installation Kit for B&W Companion 5th Wheel Trailer Hitches # BWGNRK1384-5W will also work as a gooseneck hitch, so if you have any gooseneck trailers to...

  • Is A Sliding 5th Wheel Hitch Needed to Tow 2021 Keystone Montana 3120rl w/ 2018 Ram 2500 Short Bed
    Unless the 5th wheel is equipped with a rotating pin box like the Reese Revolution/Sidewinder or Lippert Turning Point or has the dished in corners, we do indeed recommend using a sliding 5th wheel hitch to prevent the nose of the 5th wheel from striking the rear of the truck cab. Assuming your Ram 2500 short bed has the factory puck system in the bed floor, the B&W # BWRVK3670 is what I'd recommend. The American made B&W features a 1 inch thick hitch jaw that holds the king pin super...

This is a great option for you as it gives you the nicest fifth wheel hitch on the market as well as the ability to easily tow a gooseneck hitch in the future if ever needed.

This will fit your truck and will give you the clean bed as they stated. I love this option and recommend it often. They only restriction is that this hitch is not compatible with rotating pin boxes so if you have a Sidewinder, Revolution, or Turning Point Pin box of your trailer this wouldn't be compatible.

  • B and W Turnover Gooseneck Hitch and Companion Hitch Recommendation for a 2014 Ram 2500 Short Bed
    The two part numbers you referenced, # BWGNRK1384-5W and # BWGNRK1384 represent the same actual part. We have separate part numbers for our different fitguides. So if you run your vehicle through the gooseneck fitguide you would see the part # BWGNRK1384 or if you ran it through the fifth wheel fitguide you would end up with the part # BWGNRK1384-5W. Both part numbers are the correct fit for your 2014 Ram 2500 short bed truck though. For a Companion hitch when you are ready you would need...

    The pin weight which is the same as hitch weight but for a 5th wheel and gooseneck trailer cannot exceed either the payload capacity or the gross axle weight rating (GAWR) on your 2015 Ram 2500. I do have access to the payload and (GAWR) figures for a 2015 Ram 2500 but they vary drastically depending on factors such as cab type, bed length, drive type, engine size, transmission, and axle ratio so I can't give you a yes or no answer but I have sent you an article which lists all these capacities...

So if you have the OEM Ram rail kit in your 2018 Ram 2500 short bed you'd want the # BWRVK3670 which fits the factory pucks in your truck bed directly. If instead you do not have the OEM rail kit you'd want the # BWRVK3400 with the rail kit part # BWGNRK1384-5W which is a confirmed fit.

  • Will B&W Companion Slider Work on 2016 Ram 2600 With Large Tires
    It is possible with any 5th wheel hitch that tires as large as your means your set up won't be level. But really that depends on your pin box height and if you can adjust it. The B&W Companion slider has a hitch height that can be as low as 17 inches, so you need to weigh that consideration against the height of your pin box. It is likely that you will need to make adjustments to your pin box height or raise your 5th wheel to make sure you tow level. To use the B&W set up on your 2016...
