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 3-1/2" 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).

Installation in 4 hours might be realistic for a shop, but my old tired bones required a bit more time. Everything lined up and fit my 2015 Ram 2500. The quality of the components are far superior to anything Chinese. I suggest air tools if you have them, and something to lift the 5th Wheel base into your truck bed unless you feel like a baddass today. I didn't run into any problems because I read the instructions BEFORE I started. Everything I needed to know was right there! 181544

  • B&W Turnoverball Gooseneck Hitch Compatibility with 2018 Ram 2500 with OEM Air Suspension
    Thanks for your question. I reached out to my contact at B&W and they said that they used to say it wasn't a fit with the air suspension and now they have changed that. They have confirmed the B&W Turnoverball Underbed Gooseneck Trailer Hitch w/ Custom Installation Kit # BWGNRK1384-5W is compatible with the OEM Air Suspension. They simply suggest being careful to pay special attention to the air lines when installing the gooseneck so you don't damage an air hose. I also recommend...

    The B&W Turnoverball gooseneck # BWGNRK1384-5W and Companion 5th Wheel hitch # BWRVK3500-5W are an excellent option and are extremely popular. This will fit your truck and will give you the clean bed as they stated. I love this option and recommend it often. They only restriction is that this hitch is not compatible with rotating pin boxes so if you have a Sidewinder, Revolution, or Turning Point Pin box of your trailer this wouldn't be compatible.

Either way, since you mentioned the B&W Companion, that's the match for the sliding fifth wheel hitch for your truck. If you have the factory prep package with the gooseneck hole and pucks, the hitch that fits is the B&W Companion OEM 5th Wheel Trailer Hitch with Slider for Ram Towing Prep Package # BWRVK3670. If...

    The B and W Companion gooseneck hitches like the # BWGNRK1384-5W that you referenced are an excellent rail system for adding a Companion fifth wheel like the Slider # BWRVK3400. The Companion hitches are one of the nicest hitch setups on the market. If you look anywhere online this is one of the highest recommended hitches from the guys who tow a lot.

  • Fifth Wheel Hitch Recommendation for 2014 Ram 2500 Short Bed That Leaves Bed Empty
    What would serve you best is an under-bed style fifth wheel rail kit. That way you'll get the free truck bed when the hitch isn't installed and you'll get the turning clearance when needed as well. Best option we have for your 2014 Ram 2500 is the B and W Companion Slider part # BWRVK3500-5W and then the rail kit part # BWGNRK1384-5W. When you remove the hitch from the bed you would get a totally empty truck bed.

  • Recommended Hitch for Towing a Camper with a 2018 Ram 2500 6-1/2' Bed
    Generally speaking, 5th wheel towing is more comfortable than gooseneck towing because it has a different connection system and 5th wheel hitches typically have something built in to help reduce the chucking and jarring you can get when towing with an in-bed hitch. The advantage of a gooseneck system is that you don't have to mess with carrying a heavy hitch which means less things you have to be concerned about when getting ready for your camping trip. Since you have a 6-1/2' bed on...

Half ton trucks could work but are not nearly as capable as the larger trucks. A long bed for sure is something you will...
