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).

This is a great item for those who want a clean flat bed when not towing a 5th wheel or goose neck trailer. It took about 4 hours to install the below bed and above bed parts by my son, grandson, and me(I supervised). We pretty much followed the online video except we did not loosen the exhaust flange nuts (we didn't need to). When it came to bolting the center piece to the cross members, we had one person standing in the bed with a rope holding the piece up through the hole while the other person installed the bolts in it. Everything lined up well when things were squared up. we did not have any problems with the installation.

Product has worked fine. Ive towed over 5,000 miles this year with no issues whatsoever.

I love it! It was easy to install and works great. I still want to add the fifth wheel attachment maybe this summer

Package was on time. Boxes were beat up, but no hardware was lost. B&W hitches are very well made. Installation was straightforward. I will buy the Companion 5th wheel hitch next.

etrailer followed through with the best customer service for me. I had placed an order but knew I would be out of town so Matt scheduled truck freight delivery for my B&W slider hitch assy 400 lb to be shipped and delivered when I would return. Timing was great, product is best quality and with etrailer videos I installed with no issues. UPS truck driver was happy as I was waiting with skid steer with forks to unload. Picked up new 14k+ lb 5th wheel same day I completed install and even made it home. Also used a etrailer coupon to get best pricing nationwide. Thanks Matt

See what our Experts say about this B and W 5th Wheel Hitch Rails

  • Under-Bed Installation Kit for 2007 GMC 2500HD Classic with 8 Ft Bed
    That is correct, the Custom Underbed Installation Kit, # BWGNRK1067-5W, installs by using existing holes in the frame of your 2007 GMC 2500HD Classic so there is no drilling required to install the frame brackets. This installation kit is designed for use with the B&W Companion 5th Wheel Trailer Hitch, # BWRVK3500 and # BWRVK3400.

  • Fifth Wheel Install Kit For A 2007 Chevy Silverado 2500 HD
    We do carry fifth wheel install/rail kits for your 2007 Chevy Silverado 2500 HD. For that I recommend the B&W Custom Installation Kit w/ Base Rails # BWRVK2500. This kit comes with all of the underbed install kit, as well as the above bed rails. I prefer this kit over others because it will be a no-drill install. Also the B&W products are made here in the USA. This kit includes industry standard fifth wheel rails, which will be compatible with virtually any fifth wheel hitch like the B&W...

  • What are the Weights of the Individual Components in the B&W 5th Wheel Hitch # BWRVK3400-5W
    I checked with my contact at B&W for the weights of the individual component parts in their under-bed 5th wheel hitch kit consisting of parts # BWRVK3400-5W and # BWGNRK1067-5W. The weight of the head unit is 75-lbs; the base weighs 207-lbs and the under-bed assembly weighs 112-lbs. For reference I have linked both the written instructions and an installation video showing this hitch being installed in a Silverado.

  • Will B&W Companion Work With Blue Ox Gooseneck on 2007 GMC Sierra 2500?
    The B&W Companion Gooseneck-to-5th-Wheel Trailer Hitch Adapter # BWRVK3500 would not work with a Blue Ox gooseneck on your 2007 GMC Sierra 2500. In order to use the Companion you would need to install the Custom Underbed Installation Kit for B&W Companion 5th Wheel Trailer Hitches # BWGNRK1067-5W. This install kit also serves as a gooseneck hitch and is a confirmed fit for your '07 Sierra New Body Style. I've added links to video reviews and installs of both parts for you to check out.

  • Recommendation For 5th Wheel Hitch For 2009 Chevrolet Silverado HD
    Depending on the total loaded weight of the fifth wheel you get, your 2009 Chevrolet Silverado 2500 HD should work for you. I did some research and found that GM has given the 2500 HD a maximum fifth wheel towing capacity of 16,700-lbs. What exactly are your limits will be determined by your vehicle model. Make sure to check your owner's manual for capacities and recommendations. If you have a 6-1/2 foot bed, I recommend the Demco Fifth Wheel Sliding Hitch, Item # DM8550034. You will...

  • B&W Companion 5th Wheel Hitch And In-Bed Wiring For A 2003 Chevrolet Silverado 2500 HD
    Yes that is correct, the Custom Underbed Installation Kit for B&W Companion 5th Wheel Trailer Hitches # BWGNRK1067-5W will work wonderfully with your 2003 Chevrolet Silverado 2500, and since you already have the B&W Companion Slider Gooseneck-to-5th-Wheel Trailer Hitch Adapter # BWRVK3400 these two will mate perfectly. Incase you don't already, I recommend also adding the Hopkins Endurance 5th Wheel/Gooseneck 90-Degree Wiring Harness with 7-Pole Plug # 41157. This kit will tee off of your...

  • Can Fifth Wheel Rails Install on 2007 Chevy Silverado With Curt Gooseneck?
    The #gooseneck you referenced is only a fit for certain year Ford Super Duty trucks and there is not a Quick Goose 2 Gooseneck that fits a 2007 Chevy Silverado. The only thing you can do is remove it and install the B&W Turnoverball Gooseneck # BWGNRK1059-5W for a Silverado 1500, # BWGNRK1067-5W for a 2500, or # BWGNRK1062-5W for a 3500 8 foot bed. You would then add the B&W Companion # BWRVK3400-5W for the sliding fifth wheel hitch or # BWRVK3500-5W for the fixed fifth wheel hitch.

  • Will the Under-Bed Rail and Installation Kit for Reese Elite Fit a 2005 Chevy Silverado 8' Bed
    The Under-Bed Rail and Installation Kit for Reese Elite Series 5th Wheel Trailer Hitches part # RP30061 which is a fit for a 2005 Chevrolet Silverado will not work on models with an 8' bed.

  • Is Demco Auto-Slide 5th Wheel Hitch Compatible with B&W Installation Kit
    The design of the B&W under-bed gooseneck install kit # BWGNRK1067-5W that accepts their Companion hitch # BWRVK3400-5W in your 2008 Chevy 2500HD short-bed does not allow use of another slider hitch, nor use of any type of adapter to allow an industry-standard type hitch to mount. You will need to completely remove the entire B&W system in order to install a Demco kit. For a Demco under-bed installation kit you will use kit # DM8551004 and either 18K slider hitch # DM8550022 or 21K hitch...

  • Will a Reese Signature Series Hitch Fit a 2009 GMC Sierra 3500 Long Bed
    There isn't an under bed installation kit that will fit the Signature Series hitch and your 2009 GMC Sierra. If you want an under bed set up you would have to replace the hitch as well. I know that isn't the best news. Your options are: B&W Companion # BWRVK3500-5W with install kit # BWGNRK1067-5W (doubles as gooseneck hitch) Demco hitch # DM8550032 with installation kit # DM8551004 Draw-Tite hitch # 9480-5W with install kit # 9465-34-5W (doubles as gooseneck hitch)

  • 5th Wheel Hitch With Underbed Base Rails for 2008 Chevy Silverado 3500 With 8 Foot Long Bed
    There are a couple of options to add a 5th wheel hitch that mounts to underbed base rails on your 2008 Chevy Silverado 3500 long bed, which I'll go over for you. In regards to towing capacity, you will want to verify this yourself in your owner's manual, but according to the online manual an '08 Silverado 3500 Crew Cab 4WD long bed with single rear wheels has a maximum towing capacity of 9,300 lbs if you have a 3.73 axle ratio or 11,800 lbs if you have a 4.10 axle ratio.

  • Best 5th Wheel Hitch with Compatible Underbed Install Kits for 2003 Silverado 2500 and 2012 Ram 2500
    The Reese Elite and the Reese Signature Series Fifth Wheel Hitches both only mount to underbed kits designed specifically for their respective hitch. Unfortunately there aren't any adapter kits or underbed systems available for your 2003 Chevy Silverado with the 8ft bed, so there isn't going to be a way to use those hitches on that vehicle. For this reason I think the best solution is using a different hitch that provides you with the ability to switch trucks and allow you to use underbed...

  • Underbed Fifth Wheel Hitch Rail Kit Recommendation for 2005 GMC Sierra 2500HD
    Surprisingly Reese does not have an under-bed Elite hitch rail kit for your 2005 GMC Sierra 2500HD. B and W does though and for that you would want the Turnoverball kit part # BWGNRK1067-5W. Then for a hitch the Companion part # BWRVK3500 is a confirmed fit that would work well.

    Those two part numbers are the same. The # BWGNRK1067 and the # BWGNRK1067-5W represent the exact same product. Since this kit is in our fifth wheel and gooseneck hitch fitguide we change the part number slightly to organize it in our systems. Ordering either number gets you the same B and W Turnoverball gooseneck hitch that fits your 2002 Chevy Silverado.

    If your Silverado 2500 is a 6-1/2-foot bed you will need a slider 5th wheel hitch; if it is a 5-1/2-foot bed you will need more turning clearance than a slider can provide and in this case you'll use a standard fixed 5th wheel hitch along with a replacement trailer pin box called a Sidewinder (also called a Revolution on the OEM side) that changes the truck/trailer pivot point from the king pin to the rotating turret on the rear of the Sidewinder.

  • B&W Companion Hitch to Fit 2009 Chevrolet 2500 HD with 6-1/2 Foot Bed and Tool Box
    The B&W Companion # BWRVK3500 is a fixed hitch and for your 2009 Chevrolet 2500 with a 6-1/2 foot bed you're going to need a sliding hitch to have enough turning clearance. The sliding Companion is # BWRVK3400-5W which will give you an 12 inches of travel to help you make sharp turns. To determine if this will be enough for you to make sharp turns you can do a little math.
