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).

The B&W under bed hitch along with the Fifth wheel companion hitch took the better part of the morning to assembly & install but was a great fit and great quality. Thank you etrailer for your help with my order and your fast shipping.
Thanks again

I pull a 19,000 Fuzion 429 toy hauler &amp it works great

The hitch came in like promised installed, took me about four hours. Instructions were really great. These guys at etrailer.com really helps. You decide which one to get for your vehicle. Prices were really good. Give these guys a try.

Definitely like this setup. Granted for a 65 year old it was little tough getting to putting in all the bolts. Having a car lift would have helped, but did not have one in my shop . Installed totally by myself, lost a washed down by fuel take and they were able to send another one out to me. Great with the Companion Fifth wheel hitch. Have been pulling my 43ft and 18,000lbs fifth wheel for a year now. No problems encountered with this set up. Would go with this set-up time and time again!! Highly recommend.

I couldn’t be more happy with this hitch, it works perfect each and every time. The installation was not bad either for my 2013 Chevrolet 2500. I would definitely recommend this hitch to anyone who’s looking. I recently installed a different brand hitch in a friend of mines 2017 f350, as I’m working on this I’m thinking to myself I’m so glad I didn’t buy this kind. Overall b&w in my opinion is the best choice on the market today.



by:
Chevrolet Silverado 2500

Excellent product installed my self in a chevy 2500 hd. Instruction were easy to follow and precise. Really like the fact that when I take my rail out you gain the whole bed of your truck back. No pins sticking up just a flat bed won't know you were able to put a 5 th whelk hick and rain in there. Only complaint is because the hitch that attached to this frame is rated at 2k its is heavy to lift when removing. But if you have a chain host and a couple straps and can back under, the problem is solved and can be done by one man.



by:

Have always depended on B&W hitches. Is a bit technical on self install, but if you have the tools and time, it can be done.



by:

Installed quickly and the instructions were easy to follow. Definitely satisfied with my purchase.

Received the the product ahead of schedule. Installation was simple with the provided instructions. Hardest part was raising my fuel transfer tank.

    The best way to have both a gooseneck and fifth wheel hitch in your 2015 GMC Sierra 2500 is a B&W Companion. The Companion installs using an underbed gooseneck hitch # BWGNRK1012-5W that has a turnoverball so you'll have a clear truck bed. In addition the Companion # BWRVK3400-5W is a fifth wheel trailer hitch that fits into the gooseneck so you can tow a fifth wheel trailer.

This will tell you where the center of the hitch will be once installed. Companion hitch # BWRVK3400-5W and # BWRVK3400 are sliders.

If you check out the install video that I attached around the 1:15 mark we show how to remove the fender liner so that the hitch can be installed.

  • How to Eliminate Chucking with a 2013 Silverado 3500 and a Sierra 346RET using a Curt E16 Hitch
    Since you already have the Trailair Tri-Glide pin box on your Sierra 346RET, I would definitely fault the Curt E16 hitch for any additional chucking your are experiencing. The E16 hitch uses a slide-bar jaw which provides a fairly loose grip around the king pin frequently creating chucking and a noisy ride. Upgrading your fifth wheel hitch will would be my recommendation for a smoother ride. The B and W Companion, BWRVK3500-5W, is an excellent hitch, but you will have to remove your current...
