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).

Custom Underbed Installation Kit for B&W Companion 5th Wheel Trailer Hitches - BWGNRK1100-5W

by:

I'm using it with the B&W 20K fifth wheel. It works fine, but in retrospect, I should have skipped the fifth wheel and changed the pinbox on the trailer to a goose neck. The fifth wheel hitch is a little cumbersome to get in and out of the truck bed.

  • Determining if 5th Wheel Trailer Hitch Head Can Be Lowered to Allow Trailer to Ride Level
    When measuring for the proper clearance for your 5th wheel, you will want to measure the space between the top of the truck bed side rails and the underside of the camper when the truck is parked on level ground. Taking this measurement on level ground helps ensure you will still have enough clearance between the truck and camper when the hitch head does pivot. For sufficient clearance, you will want to have 6 inches between the truck bed sides and the trailer. The B&W Companion 5th Wheel...
