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).

  • Best 5th Wheel Hitch For a 2020 Chevy Silverado 2500HD LTZ Short Bed
    The best fifth wheel hitch for your 2020 Chevy Silverado 2500HD LTZ Short Bed is the sliding version of the B&W Companion because of its powerful jaws and cushioned bushings which combine to give you the quietest, more enjoyable towing experience available. You did not say if you had the factory 5th wheel prep package from GM or not, so here is what you need depending on if you have that: - 2020 Silverado 2500HD WITH Factory Pucks: B&W Companion OEM 5th Wheel Sliding Hitch for Chevy/GMC...

    I do have an option for you but there is not an aftermarket under bed 4 puck system like what you are wanting for the 2020 GMC 2500 6-3/4 ft bed. I recommend to use the B&W Companion 5th Wheel Trailer Hitch w/ Slider part # BWRVK3400-5W with the Custom Under Bed Installation Kit part # BWGNRK1020-5W. The B&W under bed installation kit doubles as a goose neck hitch so it gives you a single hole in the bed for the B&W Companion to attach. When you are not using the Companion you can...

    We have just what you're looking for. For the underbed installation kit I recommend using the B&W Turnoverball # BWGNRK1020-5W, which I really like because it also allows you to tow gooseneck trailers. With the Turnoverball system, you'll then need to use the B&W Companion Slider Hitch # BWRVK3400-5W. The Companion hitch is well known for it's durability and the 1" thick jaw provides great security and 360 degrees of jaw to kingpin contact. Additionally, the fully articulating hitch head...

  • Recommended 5th Wheel Rail Kit That Leaves Clean Bed When Hitch Is Not Installed
    I have a solution for you, but installing and then removing the bed rails after each use is going to cause undue stress on the hardware components on the bed rails; these components are designed to be installed once and discarded after installation, so there isn't going to be a rail kit that can be used in this manner. For this reason, I can't recommend using a kit with above bed rails like the B&W # BWRVK2505, which provides industry standard 5th wheel rails to mount a hitch in and instead...

    The only option that I can offer you now (September 2019) to obtain above bed industry standard base rails on a 2020 Chevrolet Silverado 2500HD is by using the Custom Underbed Installation Kit part # BWGNRK1020-5W with the Curt X5 5th Wheel Base Rails Adapter part # 16310. That said, this is not a bad option by any means as it allows for you to tow a gooseneck trailer if needed and you would have a clean truck bed with the adapter removed.

    The factory puck system is not a standard feature that is included on trucks, and would be an option that is added on to certain trucks. If your truck does not have the pucks in the bed, then it's not going to have the components needed available. The good news is that there are underbed mounting systems that will give you the same clear truck bed as the puck system would. You can add an underbed system like the B&W Turnoverball # BWGNRK1020-5W that will put a gooseneck hitch in your...

  • How to Choose Correct 5th Wheel Hitch to Clear Bed Sides of 2020 Chevy Silverado 3500
    You are correct that some newer pickups have taller bed sides that make it a little more complicated to ensure that your trailer remains level while you have enough clearance between the bed rails and your 5th wheel trailer. While I can't tell you exactly what you need to ensure proper clearance all around for your 5th wheel trailer and your 2020 Chevy Silverado 3500, I do have some tips for you to follow so you can be confident with your towing rig.

The B&W Companion line of hitches are considered by many to be the absolute best on the market.

    I have a solution for you, but if you've got a Demco Hijacker Auto-slide 5th wheel hitch, those are not compatible with the B&W Turnoverball. Instead you will need a new slider hitch; I recommend using the B&W Companion Slider Hitch # BWRVK3400-5W that fits in the B&W Turnoverball # BWGNRK1020-5W for your 2020 Chevrolet Silverado 2500. If you've got a non-autosliding Demco 5th wheel hitch you can use the Demco 5th Wheel Base Rails Adapter for B&W Turnoverball Gooseneck Hitches # DM6140. I've...

  • Are B and W Turnoverball Gooseneck Part # BWGNRK1020 and # BWGNRK1020-5W the Same
    The part numbers # BWGNRK1020 and # BWGNRK1020-5W are the exact same Turnoverball gooseneck hitch. We have two part numbers for it though as it shows up in two parts of vehicle fitguides as it works as a gooseneck hitch by itself or as the base rails for a Companion fifth wheel hitch. Our pricing sometimes fluctuates based on how certain part numbers are selling. Best solution I can recommend is go with the one that costs less!

  • Do I Need a Fifth Wheel Slider for Towing a Grand Design Reflection 31MB with a 2020 Silverado 2500?
    There are a lot of great options for fifth-wheel hitches for your 2020 Silverado 2500. You might be able to get away with using a fifth-wheel hitch without the slider option, but for vehicles with a short bed, it is almost always recommended. Without it, you could have difficulty maneuvering the trailer on tight corners and could even damage your truck and camper if not careful. The B&W Fifth Wheel Hitch # BWRVK3770 you were looking at actually does not fit your vehicle. Instead, I...

  • Can Base of Sliding 5th Wheel Hitch be Swapped Out for Long Bed of 2020 GMC Sierra 3500
    In general you can definitely swap out the base of a 5th wheel hitch so that you can change it from a stationary option to a sliding hitch. There are a handful of options for your 2020 GMC Sierra 3500 that hinge on whether you have the OEM prep package or not. I personally really like the B&W Companion 5th wheel hitches because they feature 1" dual jaws and a cam-action latching handle which combined ensures that your king pin sits solid in the hitch head but also allows you to easily release...

    Congrats on the new vehicle purchase! The main differences between the A25 # C16180 and Q25 # C16265 are that the A25 has a fully articulating torsion head and a 2-jaw system that overlaps while the Q25 had a spherical axial bearing for 360 degree head movement and an older 2-jaw system where there is a little space between the jaws. I recommend going with the A25 as it is the upgraded Q25 and the overlapping jaws provide a much more secure connection to the king pin. Please note that...
