This setup is made for serious fifth-wheel hauling. With a gross towing weight rating of 20,000 lbs and a vertical load limit of 5,000 lbs, it gives you the strength to pull heavy campers or toy haulers with confidence. The wide-stance base and gray powder coated steel frame add stability and corrosion resistance for dependable performance trip after trip.
The 1" thick dual jaws wrap completely around the king pin to give 360-degree contact that cuts down on rattle and movement compared to slide-bar jaws. Polyurethane bushings sit between the pivot arms and the hitch head to absorb road vibration. Together, they deliver a smoother, quieter ride that limits chucking and makes long hauls more comfortable.
The cam-action handle is designed to latch and release smoothly without binding, even when you’re parked on uneven ground. Once locked, it holds securely with a pin and clip, or you can replace the clip with a padlock (5/16" shackle diameter, 3" height, 2-1/4" width) for added peace of mind. When it’s time to unhook, just pull the handle—if there’s pressure on the jaws, easing the truck forward releases them cleanly.
Three height settings and two fore/aft mounting positions make it easy to dial in your trailer level and cab clearance. The pivot arms bolt into place so you can position the head exactly where it needs to be over the axle. The fully articulating head pivots front to back and side to side for smoother transitions over bumps and grades.
When you’re done towing, pull the head off the base and lift out the assembly for complete bed access. The Turnoverball gooseneck hitch that comes with it doubles as the mounting point for the fifth wheel and lets you switch between hitch types without extra parts. Flip the 2-5/16" ball over in its socket when not towing to leave your bed open and ready for work or gear hauling.
This fifth-wheel trailer hitch is not compatible with Sidewinder or Revolution king pins. Do not use any device that changes the pivot point of your trailer's king pin with this hitch.

Today we're going to review part number BWGNRC959. This is the B & W Turnoverball Underbed Gooseneck Trailer Hitch with a thirty thousand pound weight capacity. This heavy duty underbed hitch will let you tow your gooseneck trailer. When you turn the ball over it'll give you complete truck bed access when you're not towing. Basically what you can do is pull the handle, lock it open, pull the ball out, flip it over, drop it back into place, and then release the handle and the pin will lock it into place. With it flipped upside down then you'll have the full truck bed access.
It does have a five-eighths inch diameter spring loaded steel locking pin on the end of this handle which will go all the way through the ball to secure it into place. Right now, with it released, the pin goes through it. It's locked into place. When you want to remove it just pull out, lock it open. You can see the hole where it slides through.
It doesn't matter which side you put it in. When you're ready to tow, drop this, again, release the pin, and that pin will go all the way across and hold it into place. Very secure. This access handle right here will be at your rear driver's side wheel well to access it. The ball itself is a single piece machined ball socket. Pull it out so you can see here.
It provides rugged durability, has a square ball base that prevents the ball from turning in the hitch during hook up, and if you look at the corners they sort of beveled them off. This is a corners only fit so when you drop it in the stow position it prevents any grime from building up in the corners inside of the hitch. Now we do offer some special specifically designed accessories. We sell them separately on our website, usually listed as related products, that make it easy to customize this hitch to fit your needs. You can also get ...
We offer a B & W companion hitch adapter. What that does, it will drop, it has a post on it. It's a fifth wheel hitch. It can drop in to there and lock into place and you'll be able to also tow a fifth wheel. They also make a ladder rack by B & W that you can also . It has a post on it that drops in there. This ladder rack will leave your truck bed side rails free and you can still carry ladders on it. This gooseneck hitch, you can see it has the spring loaded safety chain hook ups, which are built in. When you go to attach your safety chain just pull up, hook it in, and it holds it into place. This is a very simple installation. To install this it does require a custom installation kit. We do sell those separately. They are vehicle specific. What you need to do is go on our website, go to our fit guide, type in the year and model vehicle, and then it'll show you what installation kit you need for this gooseneck to install on your vehicle. The only thing is on your truck bed you would need to cut a four inch diameter hole so this would come through and you'd have access to the opening. The finish on this is a powder coated steel which is very sturdy and corrosion resistant. This part is made in the USA. A few specs on it, again, the gross towing weight capacity is thirty thousand pounds. The tongue weight or pin weight capacity is seventy-five hundred pounds. The ball size is an industry standard two and five-sixteenths gooseneck ball. It does come with a limited lifetime warranty. Again, just to show you, if you're ready to tow with it you just drop the ball into the opening, release the pin, and it will lock it right into place. When you're wanting to stow the ball you just pull it, twist it, and you'll see on top there's a slot that'll open and then a cutout, and it shows you where you can just lock it open, pull up on the ball, there's a little handle here you can hold on to, turn it over, drop it down, release that pin, and it's locked into the stowed position, you have the full truck bed access then. That should do it for the review on part number BWGNRC959. This is the B & W Turnoverball Underbed Gooseneck Trailer Hitch with the thirty thousand pound weight capacity. .

Thanks for your kind words, Stephen! We do our best and are always happy to hear when we do it right! ^___^ And I agree about B&W parts. They are beefy and can last a lifetime. Plus they are American made! Always a plus in my book. What are you going to be towing?

One year later and zero complaints. The hitch operates smoothly with no signs of wear. Still very pleased! My 5th wheel weighs in around 15,500lbs loaded and we even pull a golf cart trailer behind occasionally. I have no reservations using this hitch.

This is by far the best fifth wheel hitch I have ever used and I have used several. It’s very easy to hitch and unhitch and I don’t have to be perfectly lined up to hitch and unhitch. I highly recommend this product.
