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!

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:
2004 Ford F-250 and F-350 Super Duty

The install is pretty easy if you have a friend to help. I'm a very mechanically inclined guy and it still took a couple of hours to get this part of the install done but my end result is perfect.

  • Can BandW Underbed 5th Wheel Install Kit # BWGNRK1108-5W Fit 2010 F-350 Dually with OEM Bedliner
    If your F-350 OEM bed liner is the drop-in type, then it will have to be trimmed to allow for any 5th wheel installation. Your tonneau cover should pose no issue, however. Spray-on bed liners are compatible with 5th wheel installations but the drop-in type has to be trimmed for installing the BandW Companion hitch # BWRVK3400-5W. Metal-to-metal contact is necessary for safe installation of a 5th wheel. This is covered in the written instructions from BandW, which are attached. This hitch...

  • 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.

  • Recommended Underbed Rail System For A 2002 Ford F-350
    There currently isn't an aftermarket puck system available for a 2002 Ford F-350 so your options for a below bed rail system are pretty limited. The best option is going to be getting a B&W Turnoverball hitch # BWGNRK1108-5W and using a B&W Companion # BWRVK3500-5W. This will give you a clear bed when not towing and you'll have the option to also tow any gooseneck trailers. B&W is known for quality and is 100% American made.

  • 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.

    We do have an option for you to use your Curt Q24 # C16245 with an underbed rail kit on your 2008 Ford F-450.

You can then use the Reese Elite Series Adapter # RP30156 which makes the puck system compatible with 5th wheel hitches that use standard base rails.

  • Will Reese Revolution Pin Box Work with B&W Companion Hitch for a 2000 Ford F-250
    The B&W Companion hitches that fit only in the gooseneck ball hole cannot be used with Reese Revolution/Sidewinder pin boxes because the pivot point is locked out at the hitch head. When using a Reese Revolution or Sidewinder style pin box the pivot point is required to be locked out due to the lateral force exerted on the hitch, like the one your referenced # BWGNRK1108-5W, would cause it to rotate in the bed damaging the hitch and install kit.
