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).

Great design and sturdy! I just is on a 2021 ram 2500 6.4 8' bed installing when great, nothing a single person can't handle. I would recommend to anyone.

Installed in my 2022 Ram 3500 dually. Install was easy due to the step by step instructions. It was nice that it was made here in USA. I didn’t have to undo the exhaust hangers. The hardest part was torquing the under bed bolts. A crows foot is the way to go. This hitch system seems great. I haven’t had it long, but this thing is rugged. My friend who has a fifth wheel with rails in his bed is thinking of getting one now. It is clean and the bed is still very usable.



by:

Outstanding product! Purchased for a 2020 Dodge Ram 2500 w/6.4L Hemi. It took my wife & I about 8 hours to install & everything went together nicely. ~2 hour delay because I wasn’t paying attention & installed the base backwards & had to build a gantry to lift it out. I definitely recommend greasing the round hitch receiver in the bed floor & the square hitch in the base before installing to make removal easier. I recommend the product & looking forward to years of goose neck & 5th wheel hitch use.

2020 Ram 2500

All is great except the release handle mechanism. Keeps getting stuck when attempting to lock the pin into the shaft opening. All the adjustments possible equals no help. Other than that installation was smooth even though it is almost impossible to get a torque wrench on the side bolts.

Installing it today and based on the instructions it looks pretty easy. Love the fact that I'll have my bed back when not hauling!

It was a straight forward install.

As expected B&W built a solid hitch, and for my 19 Ram 2500 they engineered the hitch to mount utilizing existing holes in the frame crossmember. Taking my time this install took me 1/2 a day and between the written instructions and an install video on etrailer it was straightforward.

Installation straightforward and easy. Had to remove rear seat. It would be helpful if this was included in instructions.

The B&W Turnover Ball Gooseneck Hitch is an awesome product. I installed on my 2020 Ram 2500 Cummins Turbo Diesel. From the time of delivery, I could see the pride etrailer.com put into shipping. The quality and fabrication of the product are superb. The directions and videos made this a very easy install; so much so I made it a father-daughter project. All bolt holes lined up perfectly without the need for corrective modifications. The issue I ran into was not having crowfeet wrenches to get into the tight spots, but once purchased, I had no further issues. Great product from an industry leader and a please doing business with etrailer.com.

My truck didn’t come with a puck system. This works great for a gooseneck or my 5th wheel hitch. Installed by myself, that was fun! Done it in my driveway. Having a lift and extra hands would be ideal.



by:

One of the only company's that i order from that have detailed instructions (made in America) that are correct. The possable difficult Areas are even outlined.
Knowledgeable staff very informed polite. Have used this company before and will use them in the future and would recommend to anyone.
Great work guy's! Good to see we still have companies in america that care about quality and customer satisfaction.

  • Options For Installing 5th Wheel Hitch In 2019 Ram 3500 without OEM Puck System
    They do not make an aftermarket puck system kit for your 2019 Ram 3500, so you have a few options to get a 5th wheel hitch installed. The standard way is installing above bed rails # C16430-204 to use a sliding 5th wheel hitch # C55DR if you have a 6-1/2' bed, or a fixed 5th wheel hitch # C16140 if you have an 8' bed. If having the permanently installed above bed rails is a buzz kill for you, then another option is installing the B&W Turnoverball # BWGNRK1320-5W will allow you to install...

  • Which B&W Hitch For 2021 Ram 2500 Short Bed
    The B&W Companion OEM 5th Wheel Trailer Hitch w/ Slider is a great hitch for those with short bed trucks. The # BWRVK3670 model is a confirmed fit for the 2021 Ram 2500 with the OEM Ram Towing Prep Package (the puck system). If you have the puck system in your truck, I suggest the B&W Companion, # BWRVK3670. If you do not have the OEM Ram Towing Prep Package, you can still use a B&W Companion model 5th Wheel Trailer Hitch w/ Slider rated for 20K but, you will need to use the # BWRVK3400-5W...

  • Fifth Wheel Hitch Mounted on a Gooseneck Ball
    Since you have a gooseneck ball welded into the flatbed, then you need a fifth wheel hitch that holds on by the gooseneck ball. The Demco # DM8550045 Recon Gooseneck-to-5th Wheel Hitch Adapter seems like the best solution. It has a gross towing rating of 21,000 pounds, and rated 4,000 pounds of vertical load. You would probably need to determine the towing capacity of the installed gooseneck ball. This will have a quick and easy installation.

  • Air Bags And B&W Turnoverball For A 2020 Ram 2500 4x4 With A 6-3/4' Bed
    The correct B&W Turnoverball installation kit for your 2020 Ram 2500 6-3/4' bed is the Custom Underbed Installation Kit for B&W Companion 5th Wheel Trailer Hitches # BWGNRK1320-5W. This kit is compatible with the B&W Companion 5th Wheel Trailer Hitch w/ Slider # BWRVK3400-5W. For an air bag kit, I recommend the Firestone Ride-Rite Air Helper Springs # F2598. These will install without drilling with a 5th wheel in the bed. These air bags also consist of 4 layers of rubber, compared to...

  • Underbed Rail Kit Solution for 2020 Ram 3500 to Carry Reese 20k Fifth Wheel Hitch
    I have an underbed fifth wheel hitch solution for your 2020 Ram 3500 long bed that will allow you to use your Reese 20k fifth wheel hitch. For the underbed rail kit you'd first want the B and W rail kit # BWGNRK1320-5W and then you'd use the Curt X5 adapter part # 16310 to convert that to a rail kit that your Reese hitch will fit. The Reese rail kit you referenced would not fit your truck.

    I would be happy to help you set up your 2020 Ram 3500 short bed with a 5th wheel hitch. You are going to need a sliding hitch to make tight turns and back up. You have two options depending on whether or not your Ram has the towing prep package. The Companion 5th Wheel Hitches below are nearly identical except for their mounting methods. Both have a 20,000 lbs capacity and offer 12" of travel for clearance. The Companion has a dual jaw design that allows for less rattle and more security...

  • Recommended 5th Wheel Hitch for 2019 Ram 2500 w/ a Short Bed
    Due to the fact that the truck has the shorter bed, you'll want to go with a sliding fifth wheel hitch to provide enough clearance between the truck cab and the front of your fifth wheel. I recommend the Curt Q20 fifth wheel hitch, part # C16541 as well as the # RP50054-58 installation kit. The Q20 features a fully articulating hitch head and a two piece jaw mechanism that holds the king pin very tightly, which provides good ride quality. The slider mechanism will give you 12" of travel. For...

  • Is There Difference Between BWGNRK1320 and BWGNRK1320-5W for 2020 Ram 2500
    There is no difference between the Turnoverball rail kits part # BWGNRK1320 and # BWGNRK1320-5W. The part number is only different so we can organize it in two places on our site. In a gooseneck fitguide and in the fifth wheel fit guide since it works for both. Then to convert to a fifth wheel hitch you'd just need the # BWRVK3500 for a fixed hitch if you have a long bed truck or part # BWRVK3400 for if you have a short bed truck and need a slider.

    Yes, you can fit the B and W Companion slider hitch part # BWRVK3400-5W in the bed of your 2019 Ram 2500 that does not have the OEM rail kit. All you need is the Turnoverball rail kit # BWGNRK1320-5W and you'd be set! This rail kit also doubles as a gooseneck hitch too which is nice. I attached an install video for the rail kit and a review video for the hitch for you to check out as well.

  • What Fifth Wheel do you Recommend for my 2020 Ram 3500 with 6.5' bed?
    By far the way to go is the B&W Companion 5th Wheel Trailer Hitch w/ Slider part # BWRVK3400-5W that you checked out. This offers a 20,000 lbs. capacity so it will handle your trailer weight with no issues. The Companion is the easiest to use slider out there with the best fit and finish available. It uses a dual jaw design and completely wraps around the king pin which eliminates most of the chucking often experienced during hauling a fifth wheel. As an added bonus this can be completely...

  • Placement of B&W Companion and Turnover Ball Hitch in Bed of 2019 Ram 3500
    Because your Ram has the built-in gooseneck crossmember under the bed, the # BWGNRK1320-5W Turnover Ball that will act at the mount for the # BWRVK3500-5W companion 5th wheel hitch will mount directly centered over the rear axle. The pivot arms for the Companion hitch will place the fifth wheel king pin one inch forward of the axle when installed in one of the three orientations shown in the provided diagram.

    The new Rhino Box from Lippert currently has no replacements so you won't be able to swap out this pin box with a Sidewinder to add more turning clearance. Because of this you'll have to use a sliding 5th wheel hitch in your 6.5' bed to help prevent the nose your 5th wheel from coming into contact with the cab of your 2021 Ram 3500.

I am not sure if you have the 5th wheel Load & Towing Groups package or if you have the Ram 1500, so I will recommend two 5th wheel hitches.
