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).

Solid platform. The slides need to be lubed often or they grab and scratch the slide bars. Once it is in, in performs well and is very solid. The base is solidly built and easy to install. The B&W sliding hitch is another story. Very heavy and difficult to remove as it has to be pulled straight out of the Reciever without binding. Since it's a slider, it is not balanced and wants to bind. I've even had to pry up one corner at a time and wedge it in place while I pry the opposite side. I'm not a small man either. 6'3" and 215 lbs. Pretty athletic build. I love not having rails in the truck, but it almost isn't worth it to me. 395048

  • The Difference Between the B and W Gooseneck Hitches for the 2012 Ram 3500
  • The main difference between the B and W gooseneck hitch part # BWGNRK1313-5W and the part # BWGNRK1308-5W is the installation kits are designed for different engine configurations. The # BWGNRK1313 is designed for diesel engine models, whereas the # BWGNRK1308 is designed for gasoline engines. There are also some other bed length and cab design application differences between the two that if you wanted to email me back with your bed length, engine configuration, whether you have the...

  • Recommended Sliding 5th Wheel Hitch for 2013 Ram 2500 Short Bed
  • Either the Curt # C16536 Q20 Fifth Wheel Hitch w/ Slider with its 20K capacity or the 20K Capacity B&W BWRVK3270 Patriot Sliding Fifth wheel hitch would be a great choice. Both hitches are high quality, and would offer you a secure, relatively smooth ride. For the Curt hitch, use the # C16426-204 rail kit or for the B&W Patriot, use # BWRVK2601. My only issue with bed rail mounted hitches is the fact that the rails remain in the bed when you're not using the hitch. If you don't use...

  • Comparing The B&W Underbed Gooseneck Hitch For Companion 5th Wheel On 2013 Ram 2500
  • For your 2013 Ram 2500, the B&W Companion 5th Wheel Trailer Hitch - Dual Jaw - 20,000 lbs # BWRVK3500-5W is the same in both comparisons so the difference is in the gooseneck underbed rails. The Custom Underbed Installation Kit for B&W Companion 5th Wheel Trailer Hitches # BWGNRK1313-5W is a fit for DIESEL models only, and the # BWGNRK1308-5W is the fit for GAS models only on a 2013 Ram 2500.

  • Availability of a B&W Slider Hitch to Fit a 2007 Dodge Ram 2500 w/ 6 Foot Bed and Mega Cab
  • Yes, the B&W Companion 5th Wheel Slider Hitch, # BWRVK3400-5W, will work in your 2007 Dodge Ram 2500 w/ 6 foot bed. The Companion slider 5th wheel hitch will use your B&W gooseneck hitch to mount to the bed of your Ram. The hitch head is adjustable height from 17 to 19 inches and the slider travel is 12 inches from front to back. I have attached two videos that on the B&W Companion hitch for you to review.

  • 5th Wheel Trailer Hitch and Install Kit for a 2013 Ram 2500 Diesel Short Bed
  • I measured some Curt rails, the same as those used in installation kit # C16426-204 and they are 1-1/4 inches tall if you measure from the top of the bed corrugations. The bolts do go through the outer parts of the rails so the bolt head height would not be an issue. I have linked a video showing installation of this kit on a 2013 Ram. The Reese options for your truck are the new taller rails that would not work for you. On short bed trucks it is recommended to use a slider hitch...

  • Fifth Wheel Hitch and Rail Kit Recommendation for a 2013 Ram 2500 Mega Cab
  • Since the Convert-A-Ball Cushioned 5th-Wheel-to-Gooseneck Adapter # CAB-C5GX1216 that you referenced does not move the pivot point further back you really do not gain much clearance for tight turns with a short bed truck. Also, if you use an offset adapter like this you can not use an additional offset adapter like the B and W extender you referenced. This would cause too much leverage on the trailer. Do you have a hitch in the bed of your truck? If not I would recommend you install...

  • Best Fifth Wheel Hitch Recommendation for a 2006 Dodge Ram 2500 Short Bed
  • Since you have a short bed truck you will need a slider hitch to allow you to make tight turns without cab interference. The best fifth wheel hitch setup we can recommend is the B and W Slider Companion hitch part # BWRVK3400-5W. The Companion hitches are often referred to as the nicest fifth wheel hitches around and what's great about this setup is that the rail kit part # BWGNRK1308-5W that has been confirmed as a fit for your truck also doubles as a gooseneck hitch.

  • The below-the-bed Draw-Tite Gooseneck hitch kit that fits the 2007 Dodge Ram 1500 6-foot-bed Mega Cab is part # 9464-35 which is one of the three Draw-Tite options for that specific truck. Long beds can use adapter # 9480 but since you have a short bed you cannot use this adapter since you will not have enough turning clearance. To keep gooseneck towing capability, add 5th wheel towing and keep a rail-free truck bed you will have to use the B&W Companion Slider 5th wheel along with their...

  • Fifth Wheel Hitch and Rail Kit Recommendation for 2008 Dodge Ram Shortbed 2500
  • Since you have a short bed truck you will have to use a fifth wheel hitch setup since otherwise you wouldn't have the clearance to make tight turns. Since you don't really like the idea of a fifth wheel hitch or rails left in the bed of your truck at all times your best option would be a underbed rail kit like the B and W Companion kit part # BWGNRK1308-5W and then the Companion Slider hitch part # BWRVK3400-5W that would fit the rail kit. When not in use you could remove the hitch...

  • Fifth Wheel Hitch Recommendation for a 2009 Dodge Ram 3500 with Turnover Ball Gooseneck
  • There isn't an adapter available that can give you the same rails you have with the factory rail kit of your 2014 Ram 3500. Since you already have a hitch that fits that truck you would need a hitch to fit the 2009 Dodge Ram 3500 short bed. For that you would want the part # BWRVK3400 that will fit the Turnover ball hitch you have and since it's a slider hitch it would give you the clearance needed to make tight turns when slid back. While this is your only option it is a great one....

  • Gooseneck to Fifth Wheel Adapter for 2010 Ram 3500
  • There is a way for you to tow a fifth wheel trailer with a gooseneck hitch but the Curt Q25 # C16265 you referenced is not compatible with the Draw-Tite gooseneck hitch in your 2010 Ram 3500. If that hitch is the Hide-A-Goose # 9464-57 you could use the Draw-Tite Hi-Rise Gooseneck-to-5th-Wheel Trailer Hitch Adapter # 9480. This hitch has a capacity of 18,000 lbs along with a 9" king pin funnel width. I've added a link to a video review of this product for you to take a look at as well.

  • B and W 5th Wheel Hitch Compatibility with 2005 Dodge Ram 2500 Diesel
  • If your 2006 Dodge Ram 2500 diesel has an 8-foot bed you will use B and W 5th wheel # BWRVK3500-5W along with Installation Kit # BWGNRK1313-5W. This hitch carries a 20K rating. If your Ram has the 6-foot bed with Mega Cab you will instead use hitch # BWRVK3400-5W and installation kit # BWGNRK1308-5W. If you have the 6-foot bed without Mega Cab you will use the same hitch but you'll need instead install kit # BWGNRK1313-5W. I have linked an install video for your reference.

  • Having a slider enables your vehicle to make normal turns during low-speed maneuvers and in narrow spaces without fear of your trailer's contacting the cab of your vehicle. Other sliders require you to get out and manually operate the slider which be somewhat of a hassle. You're correct that the B&W Patriot # BWRVK3270, is a great fifth wheel hitch. It uses a dual jaw and has a maximum capacity up to 18,000 pounds. to use the Patriot in your Ram you need an install bracket kit like#...

  • Correct B&W Companion Fifth Wheel Hitch for 2012 Dodge Ram 3500

For a 6-1/2 foot bed you need the B&W Companion 5th Wheel Trailer Hitch w/ Slider # BWRVK3400-5W. For an 8 foot bed you need the B&W Companion 5th Wheel Trailer Hitch # BWRVK3500-5W.

The Companions are considered by many to be the best available hitches on the market because of their 1 inch thick dual jaws that provide a great connection to the trailer and a fully articulating head that will ease hookup and limit chucking.

  • Best Hitch Setup for a 2012 Ram 3500 for a Gooseneck and a Fifth Wheel Hitch
  • The B and W Companion hitch like part # BWRVK3500 would be the best option for you. To install this hitch you will need the correct rail kit though, (this doubles as the gooseneck hitch), for that you would want the part # BWGNRK1313-5W if you have a diesel engine or part # BWGNRK1308-5W if you have a gas engine. The spray-in bed liner you have in the bed of your truck will work well with the Companion hitch. The hitch won't damage the liner, nor would the liner need to get removed.
