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).

well worth the money. this hitch is the best that money can buy, best ratings, best safety, best performance hands down. I now have two ways to tow, gooseneck and traditional 5th wheel receiver, and a third if you count the class III rear receiver hitch under the rear bumper. all bases have been covered for me.

its been a year and still going strong. Ive taken many trips and the hitch has held strong and reliable. I couldnt ask for more, except... it is heavy, so removing the base unit to utilize the bed is troublesome if youre removing it yourself like I have to. Simple solution though, I bought a gantry crane so now all i do is drive under the crane, hook up to the hitch and remove with a winch. Easy peasy!



by:

Easy to install and nice to have it hidden under the truck bed. Converted 5th wheel over to a gooseneck and couldn't be happier with the ride now.

I will update once we open up the boxes but the one box is damaged. Hoping everythin is there. Will update but once my husband opens the box.

Have you had a chance to check out the product to see if there is any damage?



by:

A one person install was a challenge, but everything matched up perfectly! Love the final look and performance! Instructions were great and detailed, videos were definatly necessary.



by:

This was a perfect bolt on for my 04 F350 6.0 CCLB I have duals on mine and I had to unbolt the exhaust the whole way up to the transmission crossmember so I had room to drill etc over the driver side tailpipe



by:

I have received this package, but have not yet installed it. It was recommended by a reliable friend, and I anticipate it will perform as advertised.

Adam at E-Trailer did an outstanding job confirming the correct package for my truck, arranging delivery, and specifying the other equipment I will need to tow my new trailer. Thank you Adam!

2009 Ford F-250 Super Duty

This is an excellent product. It was recommended to me by more than one person who were both huge fans of it. Installation is a lengthy process. and I had a little trouble with interference with a brake line, but that is nothing against the product itself. Very high quality, and very good instructions for installation. Love how it has so little impact on the usability of the truck bed.



by:

One year later, still as solid as when I put it in, no creaks or odd noises. Would recommend if you're on the fence about it.

2003 Ford F-250 Super Duty

I had a short box 2003 F250 with a Hidden Hitch. I wanted to purchase a B&W Companion Sliding Hitch to accommodate the clearance issue between the front of our first 5th wheel camper which was a Palamino Puma 5th wheel and the cab of the truck. The truck had come with a Hidden Hitch goose ball system which I had never used. The salesperson at etrailer informed me that the B&W Companion Slider Hitch would not work with the Hidded Hitch Gooseball set up. I was disappointed to hear this, but I really had no other options. After removing the old Hidden Hitch system and installing the new B&W Gooseball hitch I could not believe how much heavier and substantial this hitch was! I then received and installed the new B&W Companion Slider Hitch. This sliding hitch was the only real option for me and after looking around at other brands of 5th wheel hitches, I know that B&W hitches Made in the USA with their Lifetime Warranty are simply the Best!



by:
2007 Ford F-250 and F-350 Super Duty

Excellent products. Both hitches (goose and 5th) came as described and were built very well! B&W does not skimp on materials. At first, thinking about how the companion secures to the gooseneck I was skeptical about the strength of the to two working in tandem. Both work flawlessly, are easy to use and the companion comes apart to reduce weight when putting in and out of truck. Timely shipping from e trailer. Best price I could find. Easy install.



by:

Excellent hitch. Use it with the companion 5th wheel hitch for a rock solid platform. Install was easy, fit finish was great. Awesome American made product.



by:
2006 Ford F-250 and F-350 Super Duty

Ordered on a Thursday and received it the following Tuesday so the shipping is fast. The instructions are short and to the point with only 2 or 3 pictures so you have to use your head to install it. Very easy installation.

Works well, easy to install, very well built, have had absolutely no problem. I would recommend this setup for anyone wanting complete use of the bed when not towing.



by:

  • 5th wheel puck/goose neck system for 2000 f350- WHAT KIND OF AIRBAGS?
    I have a solution for you, but unfortunately there is not an aftermarket combination Gooseneck hitch and puck system mounting kit available for your 2000 Ford F-350. Additionally, without knowing which air bag system you have installed, it's tough to confirm what will be compatible. With that being said, the best way to tow a 5th wheel and also have a gooseneck hitch available in your truck is by using the B&W Custom Underbed Installation Kit # BWGNRK1108-5W paired with the B&W Companion...

  • 5th Wheel Install Kit & Hitch for a 2018 Ford F-150 w/5-1/2 Foot Bed & Trailer w/Revolution Pin Box
    You would need to go with an above bed rail system because there are no compatible under bed 5th wheel mounts for the 2018 Ford F-150 with 5-1/2 Foot bed. For an installation kit I recommend Reese custom kit # RP56034-53. This kit is the easiest to install because the connections between the rails and frame brackets are all on the outboards sides of the frame where they are easier to reach. For a 5th wheel hitch the Reese 16K # RP30047 is the tried and true workhorse. It has been around...

  • Will Demco Recon Gooseneck to Fifth Wheel Adapter Work with B and W Gooseneck Hitch
    Yes, the Demco Recon Gooseneck-to-5th Wheel Trailer Hitch Adapter # DM8550045 will work for you as it is designed to attach to the gooseneck ball of your hitch when securing so it will work great with a B and W Turnoverball part # BWGNRK1108-5W you have installed in your 2008 Ford F-250. Another option is the B and W Companion hitch that is designed to specifically work with this rail kit which if part # BWRVK3500.

The Companion is considered by many to be the highest-quality fifth wheel hitch available. With nearly 400 reviews from customers who have purchased it, the Companion has gotten a nearly unanimous 5-star rating. It features dual jaws...

  • Difference Between B&W BWGNRK1108 and BWGNRK1108-5W Turnover Ball Gooseneck Hitch
    There is no difference between the two. We have two similar but different part numbers because we market the # BWGNRK1108 as a gooseneck hitch and the # BWGNRK1108-5W as the mount for the # BWRVK3400 sliding version of the B&W Companion 5th wheel hitch for short bed trucks or # BWRVK3500 for long bed trucks. By having two different part numbers for the identical part, the hitch is easier to Google search for. If you'd like to install a 7-way trailer connector in the truck bed so you...

  • Recommended 5th Wheel Hitch for 15K KZ Durango 5th Wheel and 2008 Ford F-350 Diesel
    Your KZ Durango Gold 384RLT 5th wheel trailer has a GVWR of 14,995-lbs so for a hitch I recommend at least an 18K rating. Safety margin in any item, whether a 5th wheel hitch, winch or jack, tends to mean a longer working life for that item since operating a product below its absolute maximum capacity will usually mean it will operate with less wear and stress. The 6.8L F-350 SRW pickup has plenty of towing capacity for this trailer. Since you have a long bed F-350 you do not need to bother...

  • Is B&W Companion Compatible With Other Gooseneck Hitches?
    The B&W Companion mounts in the B&W Turnoverball that doubles as a gooseneck hitch and will not mount on other goosenecks. B&W is a very high-quality hitch and you are right to prefer them but the only way to install a Companion is to remove your current gooseneck and put in the Custom Underbed Installation Kit for B&W Companion # BWGNRK1108-5W and add the Companion Slider # BWRVK3400-5W.

    There is an underbed mounting system for a B&W Companion 5th wheel hitch that fits your 2008 Ford F-450 Super Duty long bed, but only for the 20,000 lb Companion, as there isn't a system that will work with the 25,000 lb OEM versions that fit in pucks.

    Yes, you can put both a 5th wheel hitch and gooseneck hitch in your 1999 Ford Super Duty. If you have a short bed you will need gooseneck hitch and installation kit # BWGNRK1108-5W.

  • Recommended B&W Companion 5th Wheel Hitch Setup for 2008 Ford F-350 Long Bed DRW
    You can indeed use the B&W Companion in your 2008 F350 DRW. You'd first need to install the B&W # BWGNRK1108-5W Turnover Ball Gooseneck hitch which would provide the attachment point of the # BWRVK3500-5W Companion 5th wheel hitch. The # RVB3500 you referred to is just the replacement base, and not the entire hitch.

  • Is There a Difference Between B&W Gooseneck Hitches BWGNRK1108-5W and BWGNRK1108
    There is no difference between those two part numbers on your end. If you ordered either part number you'd get the same B and W Turnoverball Gooseneck Hitch part # BWGNRK1108. We have two part numbers though as this hitch shows up in the gooseneck and fifth wheel fitguides since Companion hitches like the part # BWRVK3400 fit it directly. The two part numbers allow us to organize them in our system and fitguides easier.

If it has a drop-in plastic liner then the liner will have to be trimmed out to allow the hitch base's "feet" to reach down to the actual truck bed itself. You may also need to trim around the gooseneck ball. The B&W Companion is among the most versatile hitch systems available and I have linked for you an installation video showing its use in a 2004 F-350.
