This custom underbed installation kit keeps the entire bed open when you’re not towing. The setup installs beneath the bed and only requires a single 4" diameter opening for the hitch ball, so you still have a clean, usable bed surface. When you’re ready to haul, the included 2-5/16" Turnoverball pops into place, giving you a secure connection rated for 30,000 lbs gross towing weight and 7,500 lbs vertical load. When the ball is turned over and stowed, you’ve got full bed access again without bulky rails in the way.
The built-in Turnoverball gooseneck hitch doubles as the base for a B&W Companion fifth-wheel hitch, letting you switch between gooseneck and fifth-wheel towing without extra drilling or new hardware. The same center ball hole serves as the mounting point for either setup—just drop in the Companion’s post or the gooseneck ball and lock it with the handle. It’s an easy way to tow gooseneck trailers one weekend and a fifth-wheel the next using the same strong, dependable foundation.

The custom mounting brackets bolt to existing holes in the frame, so there’s no need for welding or frame drilling. You only drill for the 4" bed opening and safety chain loops. The handle is positioned near the driver-side wheel well so you can easily release or lock the hitch pin from outside the truck. All components are made from powder-coated steel for corrosion resistance and long-term durability, giving you a solid and lasting underbed towing setup.

Whole system still working well, no rusting or seizing of components. Only issue I have had was one of the bolts on the exhaust lowering bracket came loose, needs a Nylock nut. Other than that, very happy with purchase.
Do you have a question about this 5th Wheel Hitch Rail?
